All independent breweries are invited to submit, with the resultant data supporting advocacy on both state and federal levels. 
This week I take a look at fermentation considerations when brewing a very high gravity beer such as an Imperial Stout or Barley Wine. Last week in Part 1, I covered several methods for achieving a very high starting gravity. Selecting Your Yeast Now that you have a high gravity wort, you need to consider […]

From a "sales" standpoint it is also easier to explain the difference between beers with fruit, than those with subtle differences in grain bill or microbes. Most people know they like cherries, plums, and raspberries... they may not know they enjoy horse blanket, minerality, or rubbery notes.
This is the third in a series of posts updating my thoughts from American Sour Beers ten years ago. The two beers featured below (Jammiest Bit and Fruit of Many Uses) were both part of the first shipment of the Sapwood Cellars Out of State Shipping Club. Memberships for that shipment are closed, but you can still sign-up now for the next shipment fall 2024 ($146/shipment including shipping). Bottles of both are still available at the tasting room!
I would almost always rather use fresh in-season local fruit over a puree, juice, freeze-dried, concentrate, and especially natural extract. Local produce tastes unique, meaning a beer that doesn't taste the same as one brewed on the other side of the country or by a larger brewery. You'll get a more complex character from having beer in contact with the stems, skins, pits etc. Working with farms, orchards, and vineyards "fits" the narrative of an artisanal product... making it look good on social media too! Not to mention our fruiting tanks (without conical and glycol jackets) work best with whole fruit rather than purees.
Talking directly to farms and orchards at farmer's markets is a great place to start. Tasting things, chatting about what sort of capacity (and excess) they might have. Sometimes you can get a good deal on seconds... but for me these often aren't worth it since it can take a lot of time and effort to sort them (going rotten before they are all ripe) and cut-out mold etc.
We've used IQF (Individual Quick Frozen) fruits several times with great results. For smaller batches I've just gone to supermarkets, found a product I like the flavor of... and bought out a couple locations. Online specialty purveyors like Northwest Wild Foods have weird things you might not find locally, like honeyberries. For lager batches we've ordered from Coloma Frozen Foods, but don't do it regularly as refrigerated shipping is expensive. Recently we've been getting our raspberries from Twin Springs Fruit Farm (which freezes their own). Using high-quality frozen fruit is something great lambic breweries do, and it allows to extend the fruiting season so you don't have to have enough tanks for all of your fruit beer at once!
That said, not all fruits are available locally. You can certainly source whole fruits from a good local produce supplier (and we have), but purees have their place too... especially in "smoothie" type sour beers. That said, there is no magic bullet on sourcing them. We've used Oregon Fruit, Greenwood Associates, Kerr/Ingredion, Asceptic Fruit Purees, Hop Havoc, Boiron, FruitGuild, and Araza. None of them are "always good" and none of them are always bad. It's often about preference. For example, Oregon Pineapple is thin, closer to juice, great for an IPA where you'll drop out the solids. Araza Pineapple is much thicker, perfect for a smoothie sour. Both taste great.
Frozen wine grapes are another great option, either juice or must. Again, I love working with local vineyards (Crow Vineyard and Winery has been especially nice to work with), but that isn't always an option! We've had good luck with Grapes for Wine and Wine Grapes Direct.
The only concentrates I've enjoyed are "freeze" concentrates (the wild blueberry and raspberry from Greenwood Associates are great). I've disliked the flavor of all of the standard high-concentration "boiled" concentrates which end up tasting like caramel, and are so thick that they are difficult to mix with beer. Granted, after an early batch with concentrates from Kerr we really haven't tried any more. On the other hand, Kerr's NFC (Not From Concentrate) raspberry juice was terrific, so I suspect the issue was the concentration.
Freeze-dried fruit can be a pretty good option for tropical fruits like mango. I've yet to find a mango puree that didn't taste cooked. The freeze-dried stuff tends to have a brighter "mango popsicle" flavor. It can be pricy, but there is a lot of flavor pound-for-pound. North Bay Trading generally seems to have the best bulk pricing.
We have a chest freezer at the brewery so we can keg fruit when it is ready, but not necessarily have to go onto it immediately. Freezing the fruit also helps break the cell walls allowing better/quicker contact and refermentation. Just make sure to line your freezer with cardboard so the bags don't stick to the interior. That's all we do for berries. Freeze them, let them thaw in the tank, then transfer beer on the next day.
When it comes to larger fruits (e.g., stone fruit like peaches and nectarines) we'll manually quarter them and discard the seeds/pits. In an ideal world we'd selectively process and freeze the fruit on a flow basis as it reached peak ripeness.
I've never had good luck with fermented citrus, so for limes, lemons, oranges, and grapefruit we use the zest. We use a Starfrit Electric Rotato Express. It struggles a bit on really large grapefruits, and we go through a couple a year as they just aren't sturdy enough for a "production" environment.
There is some science that cherry stems have glycosides that Brett can work on to free fruity aromatics... but in practice I find they add a "stemmy" flavor that reminds me of dried leaves. I like the pits though. Obviously nice to find a source that has your preferred processing so you don't have to do it!
However you process the fruit, purge the tank with CO2 thoroughly before transferring beer in. This will help ensure the brightest, freshest, fruit expression possible!
We usually repitch rehydrated (with StartUp/GoFerm) wine yeast along with the fruit to ensure a rapid refermentation, scavenge oxygen, and enhance the fruit character. While our sour beer production area has "light" HVAC, we don't have jackets for our fruiting totes (Flextanks). As a result, we'll change our yeast depending on the seasonal temperature. Usually using more heat-tolerant red wine strains in the summer, and cool-loving whites in the winter.
We also add a small amount (5-7 PPM) of hop extract to prevent additional acidification if the beer is already sour enough for our tastes. See my article on hopping sours for more details.
I've slowly come to be an advocate for relatively short contact time, enough to ferment out the sugars, but not much more. This is especially true of raspberries (which develop a "seedy" flavor from extended contact). I've also heard strawberries as a quick-contact to reduce the phenolic "plastic" flavor they can develop. Although I've also read that can be varietal specific, and others claim freeze-drying can help mitigate.
If I'm aging a beer on raspberries and another fruit that I prefer longer contact, I'll do that separately in two totes. That way we can keg off the raspberry after 10-14 days, while the cherries, wine grapes etc. have a little more contact time (1-2 months). They we blend them together. This could also be accomplished sequentially by racking the beer off of the raspberries and then onto the cherries.
Our Flextanks have stainless steel filters from Utah Biodiesel Supply fitted over the racking arms with stoppers. A false bottom would likely work even better, but with a slow transfer we haven't had many issues with whole/pieces of fruit. The lone one I remember causing havoc with chunks of frozen mango that totally disintegrated.
With all the time and effort of getting the fruit and processing it, we often try to get a second beer out of it. Second use fruit is more subtle, allowing a more "beer-forward" balance. You could likely get similar results from ~25% of the fruiting rate, but second use fruit is easier (and free)!
We'll often just push in a single keg of sour beer onto the fruit from a whole batch to "rinse" it. This gets a big fruit character and it's an easy way to make a unique one-off
We'll do a whole new batch onto especially high fruiting rate beers. For example when we did 4 lbs/gal of raspberries in Throwing Hearts with Other Half, we went onto the fruit with a sour red along with vanilla beans to make Galactic Swirl.
For Fruit of Many Uses, we racked the beer sequentially into each tote after a previous beer. Getting Chardonnay grapes (from Field Learning, our Bissell Brothers collab) before going into barrel, followed by raspberries, then cherries (both from Jammiest Bit), and white nectarines (Polite Company).
We haven't tried it, but I know some brewers who will knock-out fresh wort onto spent fruit as a way to get fruit flavor along with a strong house culture.
No matter your technique, be extra mindful of limiting oxygen exposure as you won't have refermentation to scavenge oxygen.
Barrel #71 Golden Strong #3 (Pils, 2-row, Chit, Wheat malt, and Flaked Wheat to 1.056 with aged Celia and Lemondrop pellets). Primary fermentation with 58W3 and some microbes from a blend of older barrels that was primarily Yeast Bay Mélange (but also various dregs from Oxbow, Jester King, and Backacre). Then aged 17 months in a second-use Malbec barrel. The culture in the barrel itself was originally derived from a De Garde bottle.
Barrel #36 Marylambic #7 (Weyermann Barke Pilsner, Flaked Wheat, and Chit to 1.044 with .5 lbs/bbl aged East Kent Goldings). Primary fermentation T58. Then aged 13 months in a third-use Pinot Noir barrel. The microbes in the oak were originally from dregs from two Floodlands bottles.
Racked into two totes one with 150 lbs Twin Springs Raspberries and the other with 150 Baugher's Orchard Sour Cherries. Both frozen and thawed. Each received 10 g of HopSteiner Alpha Extract, and fresh 71B for refermentation.
Smell - Mix of fresh berries, raspberries more than cherries. Not a hugely complex funky or "Brett-forward" beer, but there is a little lemon and hay Barrel character is hidden behind the fruit as well.
Appearance - Crystal clear, brilliant red-purple. Light-pink head fizzles quickly, but stays as a thin covering.
Taste - Cherries come through more on the palate. Good fruit intensity, still really fresh/vibrant. Firm acidity, slight sharpness from the malic acid of the cherries? Again not an especially complex or funky beer, but it’s a showcase for good fruit. The Baugher's cherries without stems seems to have been a good choice. A bit sweet which lends a more Flemish Red lean rather than Lambic or Saison.
Mouthfeel - Medium-high carbonation. Medium-light body.
Drinkability - It grows on me as I drink it and my palate gets used to the acidity. Good blend of fruit, bright flavor, I just wish the base beer was a little more interesting.
Changes for Next Time - Wouldn’t mind depitted cherries to make sure we are getting good extraction.
Base Beer: Belgian Pale #3
78% Murphy & Rude Virginia Pilsner
18% Murphy & Rude Wheat Malt
4% Murphy & Rude Vienna Malt
OG 1.047
.5 lbs/bbl 5-year-old Australian Summer Hop Pellets
Primary Yeast Lalvin 71-B
Microbes from Chardonnay Grape tote (originally a Bissell Brothers house souring culture they sent for the collab).
Then aged in a third-use Cabernet Sauvignon (microbes originally from Modern Times House of Sand) and Barrel #41 fourth-use merlot barrel for 11 months (microbes in barrel included East Coast Yeast Senne Valley, Bokkereyder dregs, Mad Fermentationist Saison, Casey, and Afterthought dregs)
Racked sequentially onto 150 lbs Twin Springs Raspberries, 150 Baugher's Orchard Sour Cherries, and 250 Twin Springs White Jade Nectarines.
Smell - The berry leads, more cherry than raspberry. Earthy hay, candied fruit salad. The nectarines and grapes don’t shine in the aroma, but they help to send it in a direction that isn’t one-note “berry.” Almost apricot brandy as it warms. I don’t taste anything off from the pits, seeds etc.
Appearance - Carbonation seems a little low. A hard pour results in only a two-finger white head. A few bubbles rising through the pale body. Good clarity.
Taste - Pleasantly tart lemony acidity, without being harsh. The nectarine comes through more distinctly on the palate. Finish is berry again, but light, bright, and juicy finish. Non bitterness.
Mouthfeel - Medium carbonation, could be spritzier. Smooth, no astringency. Light body, without being thin.
Drinkability - Really complex with the different fruit notes coming in and out of awareness.
Changes for Next Time - The Chardonnay is mostly lost, would be a better feature in a plain beer or maybe light dry hopping.
This week I cover the topic of osmotic shock in yeast, and how it can impact the fermentation performance of very high gravity beers, meads, wines, and concentrated seltzers. Osmotic Shock in Yeast Cells I had never heard of the term osmotic shock until I started making very high gravity meads. Some of my large […] 
The longer I brew mixed-fermentation beers, the more I appreciate just how important the hopping rate is. Controlling lactic acid production by inhibiting lactobacillus is hops' most well-appreciated function in sour beers. Hop compounds become more effective at inhibiting Lactobacillus as the pH drops, creating a natural "limit" on their lactic acid production. What it took me a long time to appreciate was how much hop compounds (beyond IBUs) lead to a greater expression of what I think of as classic Brett "funk."
When Scott and I began the mixed-fermentation program in 2018-2019, generally our issue was beers not souring enough. I started pulling levers (lower hopping rates, higher mash temps, less attenuative primary strains etc.) By 2020-2021, we were having excessive acid production... Most non-fruited beers were dropping to a firmly-acidic 3.1-3.3 pH, while fruited beers were often difficult to drink in quantity at 3.0-3.1 pH with some dipping to "obnoxiously acidic" high-2s.
Fruit contributes simple sugars, which Lactobacillus love, and at the same time dilute the hop compounds in the beer. This can cause a precipitous pH drop. With so much beer already in barrels, my first maneuver was to begin dosing alpha acids into the beer along with fruit when there was already enough acid. We started with reduced iso-alpha-acids (e.g. tetralone/hexalone), but have moved onto Hopsteiner Alpha Extract 20% since it doesn't add perceived bitterness. About .1-.2 g per gallon stops acid production for our bacteria. These products don't significantly change the flavor or add additional aromatic complexity. As a side benefit, they enhance head retention. A small dry hop at this stage would be another option if you wanted stop acidification and add hop aromatics.
At this point we started upping the aged hop rate, or aiming for higher IBU targets when using fresh hops (~15-20 IBUs). At the same time (~2021) Scott and Ken (our head brewer) wanted to try barrel-aging more aromatically hoppy beers... I was resistant. I love hoppy-sour beers, I did a whole talk about them at the 2016 National Homebrewers Conference. Generally my approach had been to make sure the hops go into the beer as close to serving as possible (e.g., dry hop a barrel-aged sour after aging, brew a quick-turn hoppy Brett saison, add a whirlpool addition after kettle souring). I'd tasted too many barrel-soured IPAs and pale ales from great breweries that smelled like "old hoppy beer." That said, Ken and Scott convinced me! At our scale it is a relatively low risk to divert a few barrels of pale ale to see what happens.
We're already "aggressive" with our measures against oxygen pick-up (purging barrels with carbon dioxide before filling, purging the barrel-tool between each fill, purging the bottles before filling etc.), but when we fill barrels with pale ale wort we pull out all the tricks. Most importantly, we selected barrels that could be refilled without rinsing, leaving several gallons of "house culture" at the bottom of each. Our goal was to start the secondary fermentation as quickly as possible to protect the delicate hop compounds. I was amazed how good the resulting beer tasted!
What has really intrigued me is that the hoppier bases have almost universally produced finished beers I'd describe as more Brett-forward (earthy, funky, fruity, horse blanket). What I don't know is why! In American Sour Beers I cited research that Brett can free glycosides in hops, so that could explain the fruity. Maybe hops are just inhibiting Lactobacillus, giving the Brett a healthier environment (in lambics Brett tends to thrive before Pediococcus dramatically lowers the pH). Maybe I'm just being fooled and higher hopping rates (aged or fresh) are adding key compounds that I associate with the "funk" in a Cantillon, Orval (and many of my favorite American mixed-ferms)! These days our typical hopping rate is .5 lbs/bbl of aged hops at the start of the boil, and .5 lbs/bbl or fresh low alpha-acid hops in the whirlpool.
Barrels of Rings is one of the bottles included with the first shipment of the Sapwood Cellars Shipping Club. It started as Rings of Light, brewed summer 2022, racked into barrels after primary fermentation, but before dry hopping. After 10 months of aging, we transfer directly from the two wine barrels into our blending tank (purged with 5.5 pounds of our selected Citra Cryo already in there). We agitated/roused and allowed to settle for a couple days, dropping the hops. Then we primed with sugar and rehydrated wine yeast (as we do for most of our barrel-aged sours) and partially carbonated the beer. As with the barrel fill, we're relying on CO2 purging of the bottles and the rapid refermentation to scavenge oxygen and preserve hop aromatics.

Tasting Notes: Barrels of Rings
(My personal notes from a few months ago)
Smell - Nice blend of citrus (orange) and earthy-Bretty-funk. Still really fresh, no oxidative or old-hop aromatics. Really varied nose with a little pine sap, hay, and melon. Another hoppy base that got funkier than most of our bases.
Appearance - Big dense white head, good retention. Light haze, very pale yellow. Attractive.
Taste - Light lemony tartness, but not sour-sour. Very saison-y. Some bitterness, but it doesn’t clash with the light bitterness.
Mouthfeel - A touch of astringency. Great sptrizy carbonation. Medium-light body.
Drinkability - Really nice. The bitterness does give it a different impression than a classic low-bitterness sour base. More saison-like.
Changes for Next Time - Really good, not much to change on this one. Gin barrels would be fun.
When visiting Epochal Barrel Fermented Ales in Scotland last year I was blown-away by how by how good (owner/brewer) Gareth Young's wild ales were aged on whole hops in the barrels for the entire secondary fermentation. I really enjoyed the first beer we did with it, Violet You're Turning Violet (Mosaic in the barrel, finished with a blend of wild and cultivated blueberries). It seems like a good option especially if you want variety in the hop intensity of a base, e.g., start with a more moderate hopped base and add hops to some barrels for blending options.
My book, American Sour Beers, is turning ten next month! I wrote it from the perspective (and experience) of a homebrewer. I wanted to experiment and learn. I really didn't know much about brewing commercially, creating consistent blends, adapting recipes as a barrel program matured, developing flavors that would sell etc. Looking back I have to ask, did my book help launch 1,000 barrel programs, without providing the knowledge brewers actually needed to succeed?
Over the last decade American craft brewing had an explosion of breweries ramping up barrel-aged sour production, followed by a pretty rapid decline (including multiple mid-sized breweries closing their programs and sour-focused breweries closing). Part of that is the inherently less-predictable nature of mixed-fermentation (when you order a cherry sour beer, what are you expecting? Kriek, cherry juice, cherry vinegar etc.). Compare that to a bourbon-barrel vanilla-bean stout where you have a pretty good idea of what the intent was. I suspect at least part of it was the oversaturation of the market combined with the high prices.
Despite brewing my first sour beer in 2006, becoming a brewery consultant in 2011, writing a book in 2014, and opening a brewery in 2018... I haven't been consistently happy with the barrel-aged mixed-fermentations I made until the last couple years. I certainly never released a beer that I thought was bad, but there were certainly had batches that were too sour, muddled, under/over carbonated, or just didn't "pop." During that time we've also released some amazing beers that I still love!
At Sapwood Cellars we've relied on our local club members, and the people who walk in the door to buy ~10,000 bottles of barrel-aged sour beer a year. That may sound like a lot, but it's less than 5% of our production (and we're a pretty small brewery). There really hasn't been much interest in barrel-aged sour bottles in our limited distribution range. They tend to be beers that sell best when you can explain them directly to the drinker, rather than just have them sitting on a shelf! If only there was a way I could talk directly to beer drinkers interested in sour beer...
The first installment of the club is $146 (including shipping) for one 500 mL bottle each of six beers:
Growth Rings 2023: Three-year-blend of barrel-aged Sours, essentially our cuvee of bases, barrels, and microbes showing off our house character. This one isn't refermented with wine yeast, so the dregs would be a good option if you are looking for microbes! It was the second highest-rated "Gueuze" on Untappd in 2023!
Barrels of Rings: Our pale ale base, mixed-fermented in wine barrels and then dry hopped right before bottling. Citrusy-funky with restrained acidity.
Jammiest Bit: Our homage to Hommage, a barrel-aged sour on loads of sour pie cherries and red raspberries. Fruity, funky, tart etc.
Botanicia: A blend of pale sours aged in gin barrels that we then infused with dried limes and quinine. A weird play on a gin-and-tonic... but with a lot more acidity and funk!
Elliptical Orbit 2023: A continuation of the "Dark Funky Saison" series still with my original collaborator and homebrew buddy Alex. For this one he roasted Geisha coffee beans and we infused the barrel-aged dark sour with Geisha cascara (dried coffee cherries).
Fruit of Many Uses: We sequentially racked the same barrel-aged tart/funky base onto second-use Chardonnay wine grapes, cherries, raspberries, and white nectarines. All of the fruit was whole/local.
Over the next couple weeks I'll be posting my detailed tasting notes on each of the beers, along with recipes, lessons learned, and suggestions for brewing something similar at home! I'll repeat for each club release, assuming enough people sign-up for the club to make it viable.
Over the last five years it isn't "one simple trick" we learned that improved our beer. It's the accumulation of 100 little things from ingredient selection, to blending, to process refinement, to equipment that we've figured out. It's sitting down with each beer, drinking, thinking, taking detailed notes, and iterating. So much of it is not doing it by myself, having Scott, Ken, and Spencer to push to do things I wouldn't have (Botanica was Ken's baby, and Barrels of Rings was Scott's). Both are delicious, and they are certainly beers I would not have brewed if it was all up to me!
We are joined by co-founder of Human Robot Beer out of Philadelphia, PA, Ken Correll. We discuss many items including: Ken’s rapid fire history in the beer business leading up […]

This July marks five years since I left my day job with the federal government to brew full-time. We filled our first barrel with mixed-fermentation saison before opening the tasting room at Sapwood Cellars. Since then, we are up to 80 oak barrels with a dedicated suite for mixed-fermentation. So, I thought it would be a good time to sit down and reflect on the lessons that Scott and I have learned over the years! The things we got right, the things we got wrong, and where we are going from here!
Luckily, we've had a pretty good run so far! We've cultivated a great group of supporters in our Wood Club. Neologism (gin-barrel-aged Cascade/Simcoe Cryo dry-hopped pale sour) was named one of Craft Beer & Brewing's Top-20 beers of 2022 by way of winning a massive blind tasting. Despite the pandemic we've been able to modestly expand (production, staff, and space)! We're even shipping beers around the US through Tavour!
I recently realized that Google discontinued Feedburner in 2021... which is why you haven't gotten an email from me in a while. I've changed The Mad Fermentationist over to a new email service, so if you've signed up you should get emails for new posts going forward! If you want more emails from me, I write the near-weekly Sapwood Newsletter (with details on new beers often including info on ingredients, process, and equipment)!
Diverse Microflora - It is certainly simpler to have a single "house" culture. It allows for relatively worry-free blending, but doesn't leave as much room for unique flavors. Maintaining multiple cultures, we have to worry about the microbes from one barrel over-attenuating in the bottle if they are more attenuative than others in the blend. However, the variety of flavors expressed and the options for blending is worth the effort at our scale. We've been even happier since we started selecting our favorite barrels and using them to inoculate subsequent batches. Now we can select which character fits a pale sour vs. a sour red.
Last week we blended our second batch of Growth Rings (three year blend). To ensure all the microbes have time to get to know each other, we blended the four barrels (all different pale base beers) into a tote. They'll sit there for a couple months to ensure the gravity is stable before priming and bottling.
Balancing Planning and Creativity - We started 2023 with a rough timeline of the 20 or so barrel-aged mixed-ferm we'll release. However, when we fill barrels there generally isn't a specific plan for which barrel will be in which beer. Pale, wine-barrel-aged beer can be delightful on it's own, or serve as a great base of fruit, herbs, or dry hopping. When we taste them, we get to decide what will make the best possible beer. However, it's also nice to have unique bases/barrels earmarked for a particular purpose. Some examples of those include Opulence (sour red with dried sour cherries in the bourbon and red wine barrels), a Brett'd Belgian Tripel in Calvados (apple brandy), or Port barrels for There Are No Edges (Vin de Céréale).

Tracking Barrels - Using Google Sheets has worked out well for us. I can sort based on fill date, final gravity, base beer etc. It allows me to sit on my couch at home and look at what beers we have in need of fruit, blending, packaging etc. Barrels still fall through the cracks (nothing is more heartbreaking than tasting a barrel that is old/stale and seeing a note about how good it was six months ago). Sometimes a beer is delicious, it just doesn't fit into a blend.
Blending with Others - Whether it is our tasting room manager (Spencer), Lead Brewer (Ken), homebrewing friends, fellow brewers (e.g., the brewers from Other Half for a collab) etc. Tasting barrels with other people helps improve your palate, riff on ideas, and make more broadly appealing results. We all have flavor "blind spots" and it is a good idea to have other people looking too. It's fun to riff off other people's ideas and come up with flavor combinations that neither of you would have made on your own.
Packaging - Our general approach to packaging has been a big success... once we started measuring the dissolved CO2 in the beer rather than relying on time/temperature/pressure. We blend barrels or transfer fruited beers to our blending tank and cold crash. The day before bottling we'll push in sugar (boiled in water) along with Premier Cuvee champagne yeast (rehydrated with a small amount of Start-Up/GoFerm nutrient). We then carbonate the beer to ~2 vol of CO2, with the sugar and yeast taking the beer the rest of the way. We fill on a bottler (XpressFill) that purges and counter-pressure fills. So far it's resulted in relatively quick/clean refermentations with reliable carbonation.
Not Allocating Time - It is easy to put-off barrel-aged beers for more pressing concerns. When there are DIPAs to dry hop, Pilsners to can, and excises taxes to exercise the sour beers are often pushed to the side. It's rare that a week or two of aging in one direction or another makes a dramatic difference... but it's hard to get the most out of a barrel program if it is always at the bottom of the priority list. We're getting better at it, but I still wish from the start I'd blocked off a specific time/day each week to taste barrels, trial blends, source ingredients, prop microbes etc.
Over-Correcting - Initially we weren't getting enough acidity in some of our beers, so we started pulling levers... colder rinsing barrels, lower hopping rates etc. Then our beers started becoming too sour, so we started veering back in the other direction. Managing a barrel program is like driving a cruise ship, it is difficult to pivot quickly! It's difficult to step back and tell if there is something causing one specific batch from being too sour (or not sour enough) or if there is a systemic issue.
I think we would have been well served to do a better mix starting early (some barrels cold or no-rise, more with just Brett etc.). This would have given us more options when it came to blending over- or under-soured beers.
Appreciating the Impact of Fruit On Acidity - Early on to help out some of those under-acidified beers, we went onto fruit. I was surprised how little additional acidity they picked up from refermentation. Sure adding a really acidic fruit (e.g., black currants for Fellow Feeling) contributed acidity, but just refermenting on wine grapes or peaches did not. However, as our cultures "matured" we suddenly had beers dropping from a tart pH of 3.5 to an obnoxiously-acidic 3.0 after going onto the fruit (2.8 pH was the lowest I measured). That's despite pitching rehydrated wine yeast to ensure a healthy and quick refermentation.
I thought maybe our resident lactic acid bacteria were becoming more hop tolerant, and the dilution of the beer with fruit was allowing them to kick into action. To test this we began adding a small amount of hop extract with the fruit (we use a 20% alpha extract from Hopsteiner). Our fruited beers stopped dropping pH nearly as much, and as an added benefit the head retention improved considerably.
Hot Side Hopping - I didn't appreciate how much of the classic funky lambic/saison profile originates with the hops. While we've always used a "restrained" dose of aged hops at the start of the boil (~.5 lbs/bbl), that just wasn't enough to give the beers the aromatic depth I was looking for. Recently we've been experimenting with a similar size whirlpool addition of cold-stored hops. So far the results are promising! I should have noticed that many of my favorite homebrewed Brett Saisons had big whirlpool additions and/or dry hopping... but those were all relatively quick turn-around and not barrel-aged. I'm glad Scott and Ken pushed to age some of our pale ales (pre-dry hopping) in barrels, an idea I wasn't excited about... but the results have been really delicious!
Barrel-aged sour beer seems to be a wide/shallow market at the moment. The people who love them are still searching them out, but the average beer drinker seems to have moved on to less "challenging" more "reliable" styles. It's hard to know how much the rapid expansion of the segment played into this loss of interest. I've heard of quite a few breweries down-sizing or eliminating barrel-aged sour beers... Luckily we still have 150 people in our Wood Club, which is a great way for us to get these beers into the hands of our biggest supporters and a base-level of sales for eight releases a year. We're aiming to make our mixed-ferm beers more "delicious" the sorts of beers that people want to drink a whole bottle of, not just drink an ounce or two at a share.
However, as we've ramped up the mixed-ferm bottle release schedule (2019 - 8, 2020 -11, 2021 - 13, 2022 - 16, and hopefully ~20 in 2023) we occasionally have bottles to spare. Rather than distribute them locally, we've partnered with Tavour (which ships to many states). They just released Homegrown Rule, a "Marylanbic" base with homegrown lemon verbena (from my yard) and pineapple sage (from Ken's garden). It's tart and snappy, with plenty of our house microbe character, augmented by the citrusy-green notes of the herbs.
