Your browser […] There are so many reviews of homebrewing gear online, but when it comes to craft brewing equipment you're lucky if you can find a forum post or two. It makes sense as there are so many more homebrewers than craft brewers... I also had more time to write before I started making beer 60+ hours a week. Now that we're a year into brewing at Sapwood Cellars, it seemed like a good time to step back and get my thoughts down about the equipment we purchased. Hopefully what follows will help a brewer starting out, looking to add something, or just wanting a sense of what things cost.
Forgeworks 10 bbl Brewhouse - $71,306
The Good: Reasonable price, solid build quality, gets the wort production job done.
The Bad: A few design head-scratchers on the mash tun. It has a huge volume below the false bottom (~90 gallons/3 bbl). The under-screen spray balls spray directly into the supports making them useless (the connection for them is also around back making it difficult to access). The torsion ring on the rakes wasn't adequately tightened when we received it causing the rakes fell off mid-mash a few batches in. No issues since properly tightening. Originally the pickup arm in the kettle extended into the center (right into the trub cone), but they swapped us our for a shorter one that is now standard.
Verdict: Satisfied with it so far, but not thrilled given things like having to pull the false bottom to clean underneath/between after the last brew of the week (the plates can be annoying to remove, but not bad compared to some other systems).
MidCo EC300 Burner - $1,070
The Good: Plenty of heat to have the kettle close to a boil by the time run-off is finished.
The Bad: The burner's control board is incredibly sensitive to moisture, just a few drops and it is fried. A fact that it would have been nice to have a warning about from Forgeworks (they said some breweries have had it happen multiple times). Otherwise it has just been a learning curve to wait longer to turn it on and throttle the gas to avoid boil-overs. Our beers are 1-2 SRM darker than predicted thanks to direct fire, but not really the burner's fault.
Verdict: Steam would have been great, but wasn't in our budget. We haven't had issues since covering the control board with a plastic baggie (we've got a spare controller too). We were told that MidCo had a waterproof housing almost complete last fall, but haven't heard an update since.
Thermaline Heat Exchanger - $4,198.72
The Good: Their website allow you to input the parameters (volume, desired chilling rate, ground water/glycol temperature) and they build a unit to accommodate. That seemed to work for us as the chill times seem to line up reasonably.
The Bad: Nothing major to complain about. In the summer we do have to slow run-off as the second stage (glycol) doesn't lower the temperature compared to ground water by more than a degree or two at full blast.
Verdict: Might have been worth it to go a bit more over-sized, but no issues with the build-quality, durability etc.
Apex 10/20 bbl Fermenters - $7,500/10,700
The Good: The price is reasonable. We've got the "new style" 10 bbls that have an easy-rotate racking. The 2 inch dumps at the bottom rarely get clogged with hops, and the 4 inch dry hop ports work well, especially with our hop doser (below).
The Bad: The 20 bbl tank is the "old style" meaning the racking arm is just a tri-clamp. Not ideal, but it works fine especially after switching to a Teflon gasket. The big issue on that tank is with the hop port, the literature said it was a 6 inch, but it turned out to be a DIN150 (European fitting). Apex had been aware of this for 6 months and it took me ordering a gasket (to confirm the size), a custom reducer, and a new clamp all from Sanitary Fittings to resolve the issue.
There is a minor issue with one of the 10 bbl fermenters as well, the sparyball arm is just a little short which makes reassembly a two person operation (one to push, one to clamp).
Verdict: Given the issues and poor service with the 20 bbl, I'm hesitant to order more tanks from them when the time for expansion comes. Especially as they don't manufacture the tanks, the only advantage of going with them rather than directly from a Chinese manufacturer would be service.
Colorado Brewing Double Keg Washer - $6,370
The Good: Great price for an semi-automated keg washer. It rinses, washes, sanitizes, and purges two kegs at a time without intervention. As long as everything is connected and the reservoirs are filled, we rarely have an issue (other than hops in the occasional keg plugging up). The cycles are customizable, so we've tweaked them. We run a double cycle on our sour kegs, and no issues so far sharing them with clean beers.
The Bad: It's been a bit of a chore to deal with the issues that have arisen in one year of use: casters fell off, weld on one of the pots failed, software "disappeared", gas solenoid failed etc.
Verdict: The company has been great at dealing with these issues as they've occurred, shipping us replacement parts, paying for a welder etc. That said, I'd rather have not spent so much time dealing with it.
Marks Mini-Hop Doser - $495
The Good: Allows us to add hops with minimal oxygen pick-up. Safer than dry hopping loose (no risk of foam-up). Ability to add hops to a tank without venting the head pressure.
The Bad: Nothing big, although expect to double the cost of the unit itself in fittings. We have 4 inch butterfly valves on our tanks and move the doser between them as needed.
Verdict: Not sure what we'd do without it... oh I do because we we're able to use it on our 20 bbl because of the wonky port size (run CO2 and hope you don't get a face full of beer).
Navien Tankless Water Heater Standard Model - $1,260
The Good: Outputs up to 180F, plenty hot for collecting water for the mash and sparge or pasteurizing a line. Relatively inexpensive to buy and operate compared to a traditional always-on HLT.
The Bad: In the winter 180F output runs at 3 gallons/min. Helps to have a tank with an electric element to speed things up, or pre-collect water the night before.
Verdict: At our scale, and without steam this made the most sense and we're still happy with it. Two units can be daisy-chained together if we want to speed things up (e.g., first heats to 140F, second to 180F).
FlexTanks - $460-$1,190
The Good: They are inexpensive compared to stainless steel totes, while being easier to use than IBCs (international bulk containers). They have standard 1.5" tri-clamp fittings and sample ports. We mainly use the 300 gallon ones to hold bulk sour beer waiting for barrels, or to dilute barrel-aged beer that is too oaky (especially with so many first-use barrels). The 80 gallon FlexTanks are for fruit additions, where the large opening makes them easier to fill and empty than a barrel.
The Bad: They can only take ~1 PSI, so most of the movement has to be from gravity. The gasket on the lids is round and doesn't have a grove to sit in. This makes it is difficult to align without dropping in.
Verdict: They were a good place to start thanks to the price, but stainless would be more versatile and foolproof if you have the money.
EuroTransport Container Dimple Jacketed - $6,595
The Good: It's a movable, stainless-steel, temperature-controlled tank. We use it as our blending tank for sour barrel-aged beers. The bottom port is for liquid in/out (with a T for the sample port), and the two side ports for the temperature probe and carbonation stone. We currently have it off the pad, so it is nice to be able to pallet-jack it onto the pad for cleaning.
The Bad: It's odd that a jacketed tank doesn't have a built-in thermowell for the temperature probe. We use corny fittings for some kegs anyway, but it is weird to have a tank like this with a gas poppet on top. While the tank is jacketed, it isn't double walled so it sweats like crazy in the summer, we need to insulate it.
Verdict: Reasonably happy with it, but it requires a bit of a unique situation (like ours) to justify this over a standard brite tank.
XpressFill XF4500 - $6,295
The Good: It's a reasonable price for a four-head counter-pressure bottle filler. Does four bottles a minute when everything is humming along.
The Bad: We had some issues early on with the fill sensor. One or two heads would indicate that the bottle was filled even when it was empty. Turned out it was a drop of condensation on the CO2 line "falsely" completing the circuit. Not a problem now that we know what to do. One of the switches won't stay in the off position, which can cause the pneumatic foot to rise unexpectedly.
Verdict: I'm happy with it. Worth the added cost over a gravity filler for us because it reduces oxygen exposure, and allows us to bottle partially (or fully) carbonated beer. Our general approach is to chill the beer in the blending tank, prime with sugar and rehydrated yeast, agitate the tank, then pump in CO2 through the stone to get to ~1.5 volumes of CO2. The yeast does its job to bring the carbonation to target in the bottle, and we don't have to worry about predicting residual CO2 in barrels stored in ambient conditions.
Update: We had to cut down the stoppers to lower the fill heights which were ~17.4 oz in our 16.9 oz bottles. That seemed to work well.
Forgeworks 10 bbl Brewhouse - $71,306
The Good: Reasonable price, solid build quality, gets the wort production job done.
The Bad: A few design head-scratchers on the mash tun. It has a huge volume below the false bottom (~90 gallons/3 bbl). The under-screen spray balls spray directly into the supports making them useless (the connection for them is also around back making it difficult to access). The torsion ring on the rakes wasn't adequately tightened when we received it causing the rakes fell off mid-mash a few batches in. No issues since properly tightening.

Uline Straddle Stacker: Semi-Electric - $3,245
The Good: It's considerably less expensive than even a used propane-powered forklift. It's good in tight spaces because it's human powered, and powerful enough to lift a rack with two barrels. Being electric, it doesn't produce fumes that could negatively effect barrel-aging beers.
The Bad: Given the legs in front, it can't get around larger pallets, or standard pallets the long way. It is propelled by pushing, and weights over 1,200 lbs (plus whatever you are moving up to 2,200 lbs more). Only one wheel turns with steering making direction changes difficult. It also needs additional height above it, which can be tricky in a building with HVAC, lights, doorways etc.
Verdict: With our relatively cramped space, a forklift doesn't make sense, this gets the job done.

My homebrewing frequency has taken a nosedive recently (surprise), but I still try to find time to brew a weird batch when I can. In August, when Scott and I drove to pick-up our first hop order in western Maryland, I noticed that Staghorn Sumac was in full bloom along I-270 . I’d read about flavoring beer with it in The Homebrewer’s Almanac, but never actually tasted a beer brewed with it. Sumac is tart and fruity, traditionally used in a tart lemonade-like beverage.
I pulled over and harvested about a pound. The range I’d read was 1-5 lbs per 5 gallon batch. Without a beer ready for them, I took the clusters of dusty berries off of the central twig, vacuum sealed them, and froze. That was enough of an excuse to brew a batch of Berliner weisse (fermented with US-05 and Omega Lacto Blend - similar otherwise to this recipe). After primary fermentation I racked 1 gallon onto the resulting .75 lbs of sumac, and another onto .5 oz of dried Turkish sumac from Penzeys for a month. Obviously if the dried version is just as good, it certainly would be easier!
Dried Turkish Sumac Berliner
Smell – Aroma is light, doughy-grain, lightly citrus and roasted pear. An odd note of cinnamon as well.
Appearance – Clear pale yellow. It’s almost so pale that yellow isn’t the right word, it looks washed out, faded. Retention isn’t great, but the tight, white head sticks around for much longer than the other half of the batch.
Taste – Bright acid without being obnoxious. The finish has an odd fall-spice note as in the nose that I suspect is from the sumac. Dry without being a desert.
Mouthfeel – Classic Berliner, light and spritzy.
Drinkability & Notes – The not-entirely-pleasant musty-herbal flavor the dried sumac provided when the beer was young seems to have mostly faded to a light spiciness. I’m not sure I’d even pick it out if I didn’t know it was in there.
Changes for Next Time – Maybe a different/fresher source of dried sumac would provide a better flavor and aroma?
Staghorn Sumac Berliner
Smell – Aroma has the generic fruitiness of Hawaiian Punch, or Hi-C, but with an herbal hint of a Ricola cough drop. I don’t get any of the base beer, at this elevated rate it is all sumac. Certainly in the same sort of flavor-family as hibiscus.
Appearance – To go along with the aroma, it has the color of Hawaiian Punch. Similar head retention too…
Taste – The same fruit flavor from the nose, but more pronounced cherry candy. It’s a really fun flavor, that doesn’t stray into cloying. Acidity is snappy, sort of Vitamin-C, quick and punchy. No sweetness, finally breaks the comparison to "fruit" beverages.
Mouthfeel – Light, medium+ carbonation, but not excessively thin or harsh.
Drinkability & Notes – Staghorn sumac is a foraged ingredient that has a real chance for broader appeal. The flavor is fun, quenching, and somewhat familiar. The color certainly doesn’t hurt either. With how much it took, a mild base beer like this makes the most sense.
Changes for Next Time – I was sort of hoping this one wouldn’t be delicious so that I didn’t have to source a couple hundred pounds to put into a beer next summer. Likely could drop down closer to .5 lbs/gallon for a more balanced beer, but it is delicious as is!

I’m hopeful I can get this formula approved by the TTB for Sapwood, as there are already a few commercial beers from the likes Sumac Sour from Four Quarters, Backroads from Suarez Family, and of course several sours and saisons from Scratch. That said, it seems like they are clamping down as I had both acorns and Eastern Red Cedar rejected already. I’ve had several brewers tell me that the step isn’t necessary unless you are getting label approval (not true) or that it is better to ask forgiveness than permission…
I'll be making the trip down to Asheville, NC March 22-23 for another round of BYO Boot Camps! As usual I'll be talking about Wood/Barrels one day and Sour Beers the other. I said it before, but this really is looking like the last one of these for me given how much time running a brewery takes!

Brewers often joke that they spend more time cleaning than on any other aspect of the job. That isn't quite true at Sapwood Cellars, but the cleaning aspect has been the biggest change from homebrewing. By comparison, wort production hasn't been that difficult or different. Sure it took a few batches to acclimate to the efficiency and losses on our 10 bbl Forgeworks brewhouse (as with any new brewing system), made more challenging by an unreliable flow meter. Even 15 batches in despite hitting our target mash temps, wort fermentability seems to be lower than expected. We're also still dialing in hop utilization given the thermodynamics involved with large wort volumes. Still, the concepts, ingredients, and techniques are all pretty similar to homebrewing.
When it comes to cleaning and sanitizing though, we've had to relearn the entire process. You really can't fill a fermentor with 360 gallon of Oxiclean Free and soak overnight or swirl and scrub... I miss those days. First, let's talk about chemicals and what they do. Our main supplier is AFCO, but Berko, Five-Star, and Loeffler all have fans. Prices seemed similar, we just didn't think about ordering until a couple weeks before we started brewing and picked the one with the quickest turnaround time. We buy most of the chemicals in 5 gallon jugs, and pump them into beakers to measure and dose.
Chemicals
Caustic (5229 Caustic) - Caustic is the primary cleaner used by most breweries. Usually sodium hydroxide based and heavily alkaline. It is ideal for breaking down and removing organic deposits (e.g., krausen rings). You can do a bit of trading-off between time, temperature, pressure, and concentration. That said, 2-3% caustic at ~150F (66C) for 20-30 minutes through the sprayball has been a pretty good place to start for us. Caustic is dangerous because it is capable of breaking down your skin (the lye used in soap making is similar). We started with a powdered caustic (Wash-It), but given the price and efficacy we transitioned to liquid.
Phosphoric-Nitric Acid Blend (5397 Microlex Special 30) - Acid helps to remove inorganic deposits, i.e., beerstone (calcium oxalate). It also helps to neutralize any residual caustic (not that there should be any with adequate rinsing) and to passivate stainless steel. Acid blend is used at similar temperatures and cycle lengths as caustic, although slightly cooler, ~130F (54C).
Five Star Peroxyacetic Acid (PAA) - While there are many sanitizers available, PAA is the most popular for breweries. At the right concentrations it is a robust sanitizer with high effectiveness. It breaks down to acetic acid, so it can be used no-rinse. It is a powerful oxidizer, which makes it important to drain any residual before fermented beer enters a tank or keg. Our bucket was leftover from the old brewery in our space, so we bought a pack of test strips and it still reads the expected concentration after dilution.
Five Star PBW - We have a bucket of this alkaline powered cleaner for soaking hot-side equipment and other gear where we don't want to have to be as careful as we would with caustic. We both used it at home, so were more comfortable with it than the Chlorinated Manual Cleaner we started with.
Iodophor (4330 Spark I2) - Similar to the PBW, it is nice to have a less hazardous sanitizer for spraying ports or soaking fittings. It is only effective on clean surfaces, so it is important to remove of detritus before expecting it to work.
Grain Alcohol - Given its quick kill times and evaporation ethanol is the ideal sanitizer for spray bottles and any surfaces that are highly sensitive (e.g., yeast culturing). Isopropyl alcohol is another option.
General Concepts
Pre-Heating - At this scale a tank has so much thermal mass that you can't simply put 15 gallons (57 L) of hot water to a tank and expect it to still be hot after circulating. As a result if you want the caustic or acid to stay hot, you need to pray hot water into the tank. A tank with an electric element (like our keg washer has) helps too.
Sprayball - Most tanks have a port that leads to a sprayball, a small metal orb that spins and sprays when liquid is forced through. These aren't always perfect, and can have blind spots, especially in ports and above it. In addition, it isn't effective at cleaning its own exterior.
Passivation - This is what makes stainless steel stainless, a thin layer of chromium atoms at the surface that prevents iron from rusting or leeching into the beer (which weakens the equipment and shortens its lifespan). With a pristinely clean surface, the oxygen in the atmosphere is enough to accomplish this, but acids (especially nitric) are more effective.
Safety
These chemicals aren't anything to joke about. Many brewers have scars gained from caustic or acid dripping onto their skin . Safety glasses, long gloves, chemical resistant boots and pants are a must when handling them. Read the safety data sheet for each chemical you are using and know what to do if some gets on your skin or in your eyes. I don't get to drink as much beer as I used to because the end of the day is usually the most dangerous time.
Scott and I prefer to have all of the tank's arms connected from the start, allowing us to use valves to direct the flow of the cleaning and sanitizing solutions. We started off using a manifold coming off the pump, but have changed to daisy-chained T's between the arms. Many brewers prefer to simply move a single output line from the pump between the arms. This requires less setup time, but more active effort once cleaning begins (moving the hose from arm to arm ~10 times through the process). It also carries additional risks if you move the hose without closing a valve.
Our Fermentor CIP Process
1. Once the beer is out of a tank, we turn off the glycol jackets and open the dump valve. We then shoot high-pressure cold water through the sprayball to remove most of the hops/yeast struck to the sides and bottom.
2. We use our on-demand hot water heater to generate 130F (54C) water to spray through the sprayball and manually through a hose to dislodge the bulk of the crud stuck to the sides/top of the fermentor. We'll run it through the pump to get good coverage.
3. We briefly remove the lower fittings on the tanks (including manway, racking arm, thermometer, sample port) to spray out the trub caught in them.
4. We blow compressed air through the sprayball at ~30 PSI with the bottom valve open for 30 minutes. CO2 neutralizes caustic, so best to remove as much as possible before proceeding. This long is likely overkill for a 10 bbl tank, but can't hurt.
5. We assemble our cleaning rig, usually a pump running to the sprayball, with a T to connect it to the racking arm and another to the blow-off.
5. We preheat the tank for a couple minutes by spraying 160F (71C) water in and letting it drain. We hook the water line in right before the pump so we can immediately go to cleaning once it is preheated. Our goal is to get the tank to read ~130F (54C).
6. We then use the hot water heater's built-in meter to send 10-15 gallons of 160F (71C) water into the tank. We dose in 3 oz of caustic per gallon (2.3%) using a stainless steel elbow on one of the ports (chasing the caustic with water to ensure it get in). We then turn the elbow down to allow that port to equalize the pressure inside the tank, while preventing caustic from spitting out.
7. I like to send a little flow through the blow-off and racking arm first to soak them during the 20-25 minutes sprayball at full pressure (60 hz on our pump - or a bit slower if it cavitates). Then five minutes through the other arms, before a final five through the sprayball.
6. Dump the caustic. Rinse each arm with hot water, then burst rinse 10 times for 10 seconds at 130F (54C) through the sprayball, allowing it to drain before each successive rinse. I'll often put 10-15 gallons (38-57 L) into the tank once or twice and recirculate at the end to make sure there is enough pressure to spray all the surfaces. You can check the pH of the drained rinse water to ensure it has returned close normal before proceeding.
2. We then take off all of the fittings (including the sprayball itself), soak them in PBW or caustic. We inspect the fittings and gaskets, rinse and put into a bucket of iodophor. For the ports we spray, scrub and spritz with iodophor before reassembling. We also take the chance to inspect the interior with a flashlight to ensure there are no deposits.
7. We run acid blend at 2 oz per gallon (1.5% by volume) using roughly the same process and times as the caustic. Significantly higher concentrations should be used on new equipment and once a year to ensure adequate passivation.
8. Usually we'll air-dry at this point unless we need the tank the following day. In that case we'll rinse and then sanitize with peroxyacetic acid in cool water at 200 PPM using the same rig, and pressurize the tank to 4 PSI of CO2 to ensure it holds. The next morning we'll dump any residual sanitizer from each port before running wort or beer in.
The whole process including sanitation takes three hours, but most of that time isn't active (just waiting for a purge, or cycle). Going longer on any of the times isn't a big deal, so it is easy to run while working on other things if you keep track of your progress and don't miss a step.
We haven't gotten a CIP cart with dedicated vessels and pump, so our biggest issue currently is that it is difficult for one of us to clean a tank while the other person brews because they require some of the same equipment. Luckily our current schedule of two batches a week doesn't make that too much of an issue.
I am by no means holding this up as a perfect or ideal process. It'll likely be viewed as overkill by some, and inadequate by others. But if you have constructive suggestions, I'd love to hear them! I'd rather err towards overkill because we're dealing with several yeast strains (including killer wine yeast, Saccharomyces cerevisiae var. diastaticus, not to mention Brettanomyces and Pediococcus in a dedicated tank), although we do have the advantage of only dealing with kegs stored cold.
Other Pieces
We addition we'll pump the same chemicals through our heat exchanger and carbonation stone. For the heat exchanger we also heat pasteurize by running 180F (82C) water for 20 minutes inline once we assemble our knock-out rig (we discard the water until we see wort before sending to the fermentor). Our keg cleaner automatically does the same process on our sanke kegs, including air and CO2 purges to recapture the caustic and sanitizer.
When it comes to cleaning and sanitizing though, we've had to relearn the entire process. You really can't fill a fermentor with 360 gallon of Oxiclean Free and soak overnight or swirl and scrub... I miss those days. First, let's talk about chemicals and what they do. Our main supplier is AFCO, but Berko, Five-Star, and Loeffler all have fans. Prices seemed similar, we just didn't think about ordering until a couple weeks before we started brewing and picked the one with the quickest turnaround time. We buy most of the chemicals in 5 gallon jugs, and pump them into beakers to measure and dose.
Chemicals
Caustic (5229 Caustic) - Caustic is the primary cleaner used by most breweries. Usually sodium hydroxide based and heavily alkaline. It is ideal for breaking down and removing organic deposits (e.g., krausen rings). You can do a bit of trading-off between time, temperature, pressure, and concentration. That said, 2-3% caustic at ~150F (66C) for 20-30 minutes through the sprayball has been a pretty good place to start for us. Caustic is dangerous because it is capable of breaking down your skin (the lye used in soap making is similar). We started with a powdered caustic (Wash-It), but given the price and efficacy we transitioned to liquid.
Phosphoric-Nitric Acid Blend (5397 Microlex Special 30) - Acid helps to remove inorganic deposits, i.e., beerstone (calcium oxalate). It also helps to neutralize any residual caustic (not that there should be any with adequate rinsing) and to passivate stainless steel. Acid blend is used at similar temperatures and cycle lengths as caustic, although slightly cooler, ~130F (54C).
Five Star Peroxyacetic Acid (PAA) - While there are many sanitizers available, PAA is the most popular for breweries. At the right concentrations it is a robust sanitizer with high effectiveness. It breaks down to acetic acid, so it can be used no-rinse. It is a powerful oxidizer, which makes it important to drain any residual before fermented beer enters a tank or keg. Our bucket was leftover from the old brewery in our space, so we bought a pack of test strips and it still reads the expected concentration after dilution.
Five Star PBW - We have a bucket of this alkaline powered cleaner for soaking hot-side equipment and other gear where we don't want to have to be as careful as we would with caustic. We both used it at home, so were more comfortable with it than the Chlorinated Manual Cleaner we started with.
Iodophor (4330 Spark I2) - Similar to the PBW, it is nice to have a less hazardous sanitizer for spraying ports or soaking fittings. It is only effective on clean surfaces, so it is important to remove of detritus before expecting it to work.
Grain Alcohol - Given its quick kill times and evaporation ethanol is the ideal sanitizer for spray bottles and any surfaces that are highly sensitive (e.g., yeast culturing). Isopropyl alcohol is another option.
General Concepts
Pre-Heating - At this scale a tank has so much thermal mass that you can't simply put 15 gallons (57 L) of hot water to a tank and expect it to still be hot after circulating. As a result if you want the caustic or acid to stay hot, you need to pray hot water into the tank. A tank with an electric element (like our keg washer has) helps too.
Sprayball - Most tanks have a port that leads to a sprayball, a small metal orb that spins and sprays when liquid is forced through. These aren't always perfect, and can have blind spots, especially in ports and above it. In addition, it isn't effective at cleaning its own exterior.
Passivation - This is what makes stainless steel stainless, a thin layer of chromium atoms at the surface that prevents iron from rusting or leeching into the beer (which weakens the equipment and shortens its lifespan). With a pristinely clean surface, the oxygen in the atmosphere is enough to accomplish this, but acids (especially nitric) are more effective.
Safety
These chemicals aren't anything to joke about. Many brewers have scars gained from caustic or acid dripping onto their skin . Safety glasses, long gloves, chemical resistant boots and pants are a must when handling them. Read the safety data sheet for each chemical you are using and know what to do if some gets on your skin or in your eyes. I don't get to drink as much beer as I used to because the end of the day is usually the most dangerous time.
Scott and I prefer to have all of the tank's arms connected from the start, allowing us to use valves to direct the flow of the cleaning and sanitizing solutions. We started off using a manifold coming off the pump, but have changed to daisy-chained T's between the arms. Many brewers prefer to simply move a single output line from the pump between the arms. This requires less setup time, but more active effort once cleaning begins (moving the hose from arm to arm ~10 times through the process). It also carries additional risks if you move the hose without closing a valve.

I have nothing against brewing to-style. You can make magnificent and delicious beers by using ingredients from a single region with the goal of a classic balance. That isn't who I am as a brewer though. The recipe for Sapwood Cellars' False Dragon is the sort that I'm passionate about. We selected ingredients from all over the globe to create a flavors and aromas that aren't authentic to any one tradition. What I wanted was an earthy-crisp malt flavor, a white-winey hop aroma (for less money than Nelson Sauvin), and a subtle spicy and fruity-boost from the yeast without getting in the way. That required malts from America and England, hops from America and Germany, and yeast from England and Belgium.
I'd been experimenting with the hop bill for a few months to get the ratio right, and eventually settled on 2:1 in favor of Mosaic. After a few test batches, Scott and I have embraced adding less expensive hops on the hot-side (Cascade, Columbus, Chinook, Centennial etc.) with the more aromatic and expensive varieties saved for the fermentor. I wanted to split my homebrewed test batch to compare S-04 alone against S-04 with 8% T-58. As with Ziparillo, dry yeast is cost-effective especially if you can't repitch thanks to early or mid-fermentation dry hopping. Belgian strains have shown heightened biotranformation abilities is some studies, so it seemed like a good candidate for double dry-hopping.
For the 10 bbl batch we decided to fill-in a gap in our range when the first batch of Rings of Light (our Citra dry-hopped hazy pale ale) came in under-alcohol at 4.8% thanks to lower-than-expected efficiency. In effect the two recipes switched places with False Dragon becoming the "bigger" pale ale at 5.3% rather than the 4.7% of the test batch. Our attenuation has been lower than expected across the board for our first five batches too. We're still trying to figure out the cause given it has happened with multiple yeast strains - likely mash related. Luckily our hop flavor and aroma have both been wildly better than either Scott or I have been able to achieve at home, I'm sure surface-to-volume ratio plays a role.
Your first chance to try this beer is at the Sapwood Cellars grand opening, Noon-10 PM on Saturday 9/29. We'll be open Thursday-Friday 4-10 PM and Saturdays Noon-10 PM from then on. Stop in, drink a beer, say hello!
The name False Dragon come from The Wheel of Time series of books by Robert Jordan. My commute has gone from 20 minutes on the subway to my desk job to ~40 minutes by car. Audio books are my new friend. While I'm sure brewing podcasts would be a more productive use of my time, after 12 hours brewing it is nice to have a little escapism.
False Dragon S-04
Smell – Had to go for a fresh pour after taking photos as it had gone a hint skunky after five minutes in the sun… Nose is a fresh “true” hop aroma to the Mosaic and Hallertau Blanc. White wine, but also some blueberry and green/herbaceous. Certainly Nelson-reminiscent, but a unique character as well.
Appearance – Pale yellow, pleasantly hazy. Good head and lacing, but the foam itself feels airy on the tongue. I guess I’ve gotten used (and miss) to the contribution of chit malt.
Taste – A firm amount of bitterness in the finish, but it doesn’t linger. Light and bright with the tropical-fruity hops starring. Rye doesn’t really make a strong showing, although I’ve always found it more subtle than some others taste.
Mouthfeel – The rye helps prevent it from being watery, but it is a summery pale ale. Glad we ended up a little higher OG/FG on the big batch. Medium carbonation, nice for a lighter beer.
Drinkability & Notes – A pleasant session IPA. The Mosaic and Hallertau Blanc work better together than apart.
Changes for Next Time – 10% chit in place of the base malt wouldn’t hurt. Could certainly up the rye too for a bigger contribution.
S-04 and T-58
Smell – More rounded, less grassy-distinct hop aroma. Tropical, juicy, inviting. The green flavors are now more honeydew melon. Impossible to say how much of that is actual hop chemical reaction, or synergistic between the hops and esters. Lightly bready.
Appearance – Looks similar in terms of head, color, and clarity.
Taste – Lower perceived bitterness. A more saturated/integrated fruity hop flavor. Passionfruit especially. I think this is the more approachable and interesting beer, and distinct from the other English-only fermentation we are doing (using RVA Manchester). Slightly elevated phenols, but much lower than from the WB-06 in Ziparillo.
Mouthfeel – Slightly creamier (perhaps just the lower perceived bitterness?), identical carbonation.
Drinkability & Notes – I was able to identify these pretty easily in a blind tasting. It is amazing how much impact such a small amount of yeast can make.
Changes for Next Time – We decided to back down the T-58 4.4% of the blend to allow a bit more of that fresh/distinct hop character through. Other than the higher gravity, the recipe was otherwise unchanged for the 315 gallon batch! We’ll probably up the rye for batch #2 now that we know we can handle higher percentages of high beta-glucan huskless grains.

There are a lot of IPA drinkers out there, but I get the feeling that there are just as many people who would enjoy the fruity-tropical flavors in New England IPAs, but were scared off by the IBU-arms-race of earlier this decade. I wanted to develop a session beer for Sapwood Cellars that showcases fruit-salad hoppiness without assertive bitterness. Sort of a Belgian white, with hops instead of spices. The result is a beer we're brewing 10 bbls of today... Ziparillo!
Dry hopping mid-fermentation is a great technique for chasing away raw-green hop aromatics that turn-off some drinkers. The problem is that adding hops early makes harvesting yeast far more difficult. Our solution was to use dried yeast. For a fraction of the price of a liquid pitch (~$60 for 500 g dried) it means we don't feel bad not cropping and repitching. Dry yeast also allows for easy strain blending by weight. In this case the test batch was 85% S-04 and 15% WB-06. The goal was to support the fruity hops with a little banana from the hefeweizen strain. An idea I first tried in my American Oat Ale.
The grist is a callback to what we developed for Modern Times Fortunate Islands, still my favorite of their regular offerings. The grains were in turn inspired by Three Floyds Gumballhead. We decided to go a bit lighter on the wheat until we get used to how large amounts of huskless grains lauter on our Forgeworks brewhouse. Hot-side hopping is a single dose of Cascade in the whirlpool. A classic variety with a good blend of oils, but without excessive alpha acids (or cost). Despite that, for the up-scale we're going to lower the whirlpool temperature to ~195F with a barrel of cold water at flame-out to keep the IBUs under 20. Dry hopping with Amarillo for stonefruit aroma.
Hefeweizen yeast, CaraVienna, Cascade, and Amarillo is a combination I tried back in 2010 for this Hoppy Hefeweizen. Not the same intended balance on that batch, but a similar palate of flavors.
The wrinkle in this test batch was that I split it pre-boil. I've been editing Scott's draft for "The New IPA" and the research suggested that many hop oils peak very quickly at higher temperatures and then dissipate. So I split the batch, half with a 20 IBU addition at 60 minutes followed by a flame-out addition immediately after turning on the immersion chiller. The other half I added a hop-stand/whirlpool addition allowing it to sit for 45 minutes before starting the chill. I even left the heat on low to better replicate the slow cooling of a commercial-scale whirlpool.
Going in I was suspicious. I'd changed from quick-chilling to hop-stands a few years ago, and felt that my beers had gotten a better more saturated hop flavor. The beers came out surprisingly similar, but not exactly the same.
Ziparillo - Quick Chill
Smell – Clean yeasty-doughy nose. Banana. Cascade grapefruitiness shines through as the dominant hop character. Certainly reminds me most of hoppy hefeweizens that I’ve brewed previously. Surprising how much yeast character there is from a low percentage of WB-06.
Appearance – Pale-gold, mildly hazy of the standard hefeweizen type. Not milky-haze. Good head retention and cling.
Taste – Bitterness is present, a bit higher than 20 IBUs in my estimate. Crisp finish with some lingering hop resin. Amarillo comes in a bit towards the end, apricot. Odd that I get the kettle hops in the nose and the dry hops in the flavor. The quick chill seems to have imparted a more dry-hop like character. Dry, with a finish that reminds me of some sort of herbal spritzer?
Mouthfeel – Snappy, good firm carbonation, but not as high as a traditional hefe. Dry, slightly tannic finish.
Drinkability & Notes – A nice session beer. The polyphenols from the early-boil addition may be making the bitterness come-across higher than the calculated IBUs would suggest.
Changes for Next Time – Drop the bittering addition to 10 IBUs, and this would be much closer to the balance I was looking for. Nice as is, but likely too bitter for many hop-phobes. Yeast character is a bit distracting.
Ziparillo - Hop Stand
Smell – Similar, but the yeast character comes across as leaning more bubblegum than banana. Slightly more phenolic as well, peppery. Hops are better integrated into the yeast character or maybe just less assertive. I get honeydew melon.
Appearance – Identical. In this case the timing of the boil hops and speed of chilling doesn’t seem to have effected clarity.
Taste – Bitterness seems lower/smoother, and the finish rounder despite the same calculated IBUs. Like the nose the line between fruity yeast and hops is less distinct than the other version. There is more banana than in the nose, but it is still relatively subdued. Hops are bright and citrusy.
Mouthfeel – Smoother, less tannic. Coating compared to the other half. That isn’t a character that necessarily sounds beneficial to a session beer, but in this case it makes it easier and more pleasant to drink.
Drinkability & Notes – Closer to what I was looking for, the hops and yeast meld together into a pleasant fruit salad. Rather than a generic fruitiness throughout the effect is different flavors from nose and mouth, evolving as it warms. One friend noted that it has sort of an Allagash White thing going on, which was exactly my intent.
Changes for Next Time – We’ll be cutting the WB-06 from 15% to 7.5% in the big batch. The taller fermentor should suppress ester production as well. We’ll add a barrel of cold water at the end of the boil to lower the temperature and further smooth the hop bitterness contributed by the whirlpool addition.

So I split the batch, half with a 20 IBU addition at 60 minutes followed by a flame-out addition immediately after turning on the immersion chiller. The other half I added a hop-stand/whirlpool addition allowing it to sit for 45 minutes before starting the chill. I even left the heat on low to better replicate the slow cooling of a commercial-scale whirlpool.
Going in I was suspicious. I'd changed from quick-chilling to hop-stands a few years ago, and felt that my beers had gotten a better more saturated hop flavor. The beers came out surprisingly similar, but not exactly the same.
Ziparillo - Quick Chill
Smell – Clean yeasty-doughy nose. Banana. Cascade grapefruitiness shines through as the dominant hop character. Certainly reminds me most of hoppy hefeweizens that I’ve brewed previously. Surprising how much yeast character there is from a low percentage of WB-06.
Appearance – Pale-gold, mildly hazy of the standard hefeweizen type. Not milky-haze. Good head retention and cling.
Taste – Bitterness is present, a bit higher than 20 IBUs in my estimate. Crisp finish with some lingering hop resin. Amarillo comes in a bit towards the end, apricot. Odd that I get the kettle hops in the nose and the dry hops in the flavor. The quick chill seems to have imparted a more dry-hop like character. Dry, with a finish that reminds me of some sort of herbal spritzer?
Mouthfeel – Snappy, good firm carbonation, but not as high as a traditional hefe. Dry, slightly tannic finish.
Drinkability & Notes – A nice session beer. The polyphenols from the early-boil addition may be making the bitterness come-across higher than the calculated IBUs would suggest.
Changes for Next Time – Drop the bittering addition to 10 IBUs, and this would be much closer to the balance I was looking for. Nice as is, but likely too bitter for many hop-phobes. Yeast character is a bit distracting.
Ziparillo - Hop Stand
Smell – Similar, but the yeast character comes across as leaning more bubblegum than banana. Slightly more phenolic as well, peppery. Hops are better integrated into the yeast character or maybe just less assertive. I get honeydew melon.
Appearance – Identical. In this case the timing of the boil hops and speed of chilling doesn’t seem to have effected clarity.
Taste – Bitterness seems lower/smoother, and the finish rounder despite the same calculated IBUs. Like the nose the line between fruity yeast and hops is less distinct than the other version. There is more banana than in the nose, but it is still relatively subdued. Hops are bright and citrusy.
Mouthfeel – Smoother, less tannic. Coating compared to the other half. That isn’t a character that necessarily sounds beneficial to a session beer, but in this case it makes it easier and more pleasant to drink.
Drinkability & Notes – Closer to what I was looking for, the hops and yeast meld together into a pleasant fruit salad. Rather than a generic fruitiness throughout the effect is different flavors from nose and mouth, evolving as it warms. One friend noted that it has sort of an Allagash White thing going on, which was exactly my intent.
Changes for Next Time – We’ll be cutting the WB-06 from 15% to 7.5% in the big batch. The taller fermentor should suppress ester production as well. We’ll add a barrel of cold water at the end of the boil to lower the temperature and further smooth the hop bitterness contributed by the whirlpool addition.

5.28 at mash temperature after all additions (~5.5 corrected to room temperature).
Split between two boils:
1. 1 oz of Cascade @60 min, and 3.5 oz of Cascade with a quick chill at flame-out (added hops right after starting IC).
2. 3.5 oz of Cascade with a whirlpool at 212F (with heat) for 45 minutes... mostly stayed 190-200F.
Chilled to 68F, pitched 1 pack of S-04 and 2 g of WB-06 into each (no rehydration). Shook to aerate.
Same fermentation, beer temp 65F.
8/7/15 Dry hopped ~36 hours after pitching. Set beer temp to 68F to continue fermentation.

I've brewed a surprising number of beers with ingredients grown on our .1 acres of Washington, DC. Including hops, cherries, juniper, ground ivy, mulberries... and recently fermented acorns! Rather than showcase a single ingredient though, I wanted to brew an estate beer with five ingredients grown and harvested on our land!
The extent of the influence of aged hops on sour beer is still a bit underestimated. While the generally stated goal is preventing rapid souring by Lactobacillus in a traditionally fermented lambic, what they add to the flavor and what particular characteristics of the hops best serve this isn't widely studied. There are a few studies that oxidation can boost certain fruity aromatics. Which has lead Scott to threaten to use old hops on the hot-side for a NEIPA... he promised to do a test batch before brewing a 10 bbl batch on the new Sapwood Cellars brewhouse.
I thought it would be fun to brew with aged Cascades from the bines in my backyard, especially because fresh they didn't have a huge aroma. They'd been sitting open in my basement since they were dried a few years before.
I don't have the space or effort to grow or malt grain, so I took the easy way out and brewed with wheat malt extract (a blend of 65% wheat malt 35% barley). I'd had good results from extract lambics previously, but this time in addition to maltodextrin I added wheat flour slurry to the boil. Mixing the flour with cold water prevents it from clumping when it touches the boiling wort. A turbid mash pulls starch from the unmalted wheat into the boil, which eventually feeds the various microbes in the late-stages of fermentation. The microbes must have enjoyed it as the resulting beers are completely clear.
Fruit was provided by our four berry trees/bushes. Sour cherry, blackberry, raspberry, and mulberry. To keep things easy I added roughly equal amount of each (other than the raspberries). I briefly froze most of the fruit, but I added the raspberries a small handful at a time as they ripen slower than the rest. I only had enough of each for one gallon of beer, as most of the rest of the fruit was spoken for. The leftover beer went onto local plums!
Video Review
Backyard Berries
Smell – Cherry and raspberry lead, not surprising as they are more distinct than the blackberry and mulberry. There is an underlining wine-iness that likely comes from the rest of the fruit. The base beer behind the fruit doesn't make itself known other than a subtle maltiness.
Appearance – Clear garnet on the first pour, a little haze when I emptied the bottle into the glass. Alright head retention thanks to the wheat.
Taste – Reminds of the nose with raspberry up front and cherry jam into the finish. Not as bright and fresh as it once was, but still reasonably fresh. The malt and hops don’t add a huge amount of character, but they support the fruit. The Wyeast lambic blend similarly stays mostly out of the way, adding edge complexity without trying to fight through the fruit.
Mouthfeel – Not a thick beer given the relatively low OG, and all of the simple sugars from the fruit. Solid carbonation, CBC-1 did a good job despite the acidity.
Drinkability & Notes – The combination of four berries works surprisingly well to my palate. They play together without becoming generic fruitiness. The base beer is unremarkable, but that’s fine in a beer where the fruit is the star.
Changes for Next Time – Would be nice to brew more than a gallon, but otherwise my only real changes would be to go all-grain.
Plum-Bus
The rest of the batch went onto a two varieties of local plums. I've brewed with plums before in a dubbel. I wasn't sure about plums in a pale beer, but after trying spectacular examples from Tilquin and Casey I was convinced!
Smell – Clear it isn’t a kettle-soured fruit-bomb, lots of lemon pith and mineral along with the moderate fruit contribution. Plums aren’t nearly as aromatic as the more common sour beer fruits, but they add a depth without covering up the base beer.
Appearance – Beer is more rusty-gold than purple. Clear despite the flour. Thin white head, but this bottle appears less carbonated than the last few I’ve opened.
Taste – Tangy plum skin, apricot, and lemon. Beautiful blend of fruit and beer. Wyeast Lambic Blend with dreg-augmentation again does a really nice job. Strong lactic acid without any vinegar or nail polish. Finish is moderate funk, hay, and overripe stone fruit.
Mouthfeel – Light, but not thin. Carbonation is too low, maybe the cap-job on this one wasn’t perfect.
Drinkability & Notes – Delicious. The plum could be a little juicier and fresher, but it works well. Sad I didn’t leave any of this half unfruited for comparison.
Changes for Next Time – I’d like to keep experimenting with other plum varieties in beer. Glad the pale base worked out well. Despite “plum” being a common descriptor for darker Belgians, actual plums don’t shine with all of that malt.
