Bootleg Biology: Mad Fermentationist Saison Blend

Bootleg Biology Mad Fermentationist Saison Blend logo.I love my House Brett-Saison culture, and for $10 now you can try Bootleg Biology's The Mad Fermentationist Saison Blend at your house (or brewery)! It's a good deal for me as I get a small cut, and the knowledge that if I kill my mother culture I have off-site backup: Order

I met Jeff Mello (Bootleg Biology's founder) while he was living in the Arlington, VA. Shortly after, he moved to Nashville where he moved his small yeast lab to a commercial space. Jeff sent me a few isolates to grow for the Modern Times souring program. In 2014 he floated the idea of isolating and packaging a blend for me, but at the time I didn't have any microbes that I thought of as mine. We could have pulled something out of a solera barrel, but honestly I never loved the fermentation character of either of them. After running a cobbled together saison blend through my sour gear 10 times over two years, sometimes harvesting from kicked-kegs, I don't know which yeast and bacteria thrived or mutated, but it makes great beer!

It has been interesting to have Bootleg Biology pull out the component microbes and put them back together. I've brewed a couple test batches with pre-release cultures with promising results (see below), that were good enough to release it and see what other brewers think! If you do buy a pack, please leave a comment here to let me know what you brewed, fermentation temperature, and the results!

You can use the blend in any saison recipe, but here are my three of my favorite batches to get you started:

Saison 'Merican
Nu Zuland
Alsatian Saison

Culture streaked on a plate.Bootleg Biology is proud to announce: The First Official Mad Fermentationist Culture!

Fine tuned over two years, this blend morphed over time to become an elegant powerhouse of classic Saison spice, stone-fruit Brett, lactic tartness and a dry but well-rounded body. The final master blend consists of Saison yeast, wild Saccharomyces, rare Brettanomyces and an opportunistic Lactobacillus culture.

At temperatures as low as 68F (20C) The Mad Fermentationist Saison Blend exhibits a relatively clean primary fermentation profile and high attenuation. Traditional saison temperatures (around 80F/27C) bring out citrus and elevated phenols (pepper and clove). The Brett character shifts depending on wort composition, as maltier beers emphasize cherry and stone fruit qualities.

This blend integrates beautifully with fruity and tropical hops, with the unique Brett culture keeping hop aromatics crisp and bright for an extended time. For best results use a highly fermentable wort, dry hopping during the tail of active fermentation, and carbonating naturally.

----------

Here are the tasting notes and recipe from the batch I brewed with the second test-pitch from Bootleg Biology. I bottled it more than three months ago, just three weeks after brewing. One of my favorite things about this blend is that it dries out beers quickly, leaving little for the low-attenuating Brett to ferment. The result is a beer that you can bottle young and enjoy as it morphs from bright saison into wild ale!

This batch was actually Audrey's first on the big system after a couple 2.5 gallon batches. I acted as assistant brewer. She was aiming for, "a dark Belgian wheat, with maltiness between a dunkelweiss and an English dark mild." She used an experimental hop supplied by Yakima Valley, ADHA-527, which they describe as: "floral, citrus, huge mint, herbal, mellow spice, thyme, Saaz-like, cucumber, sage, touch of lemon." Seemed like some good and bad, a nice pairing with funk!

Finished beer, on my microbe shelf.Europa Lander

Smell – Fermentation leads with toasty malt following. Still has some underlying Belgian spice and pear, but Brett is beginning to takeover. It is a really approachable leather-cherry funk though. Nothing over-the-top or too animalistic. Maybe a hint of anise and a little clay, hard to place the source.

Appearance – Clear, perfectly not a hint of haze. Pretty light-brown beer-bottle color. White head exhibits solid retention.

Taste – The caramel malt plays with the funk. Chocolate rye provides more toasted bready than harsh roast. Still a fresh maltiness despite the layer of leather and cherry from the Brett. No acidity thanks to the hint of hop bitterness. Dry, but with enough left to support the malt. Subdued hop bitterness.

Mouthfeel – Firm carbonation, nothing excessive. Glad this blend retained the ability to dry out a beer quickly and stabilize. Doesn’t taste as thin as the FG would suggest, but it’s no milkshake!

Drinkability & Notes – I can’t think of a beer to compare this to. Really balanced between malt, hops, and fermentation in a Belgian sort-of-way, but not in a combination I’ve tasted from a Belgian or Belgian-style beer.

Changes for Next Time – Not a blow-you-away beer, but I can’t think of a tweak to suggest that wouldn’t changing what it is: a unique malty, funky, subtle, drinkable beer!

That is one clear beer.Recipe

Extract Lambic Tasting (Plus Peaches)

Drinking malt-extract-based lambic outside.Over my first 10 years of brewing "lambic-inspired" pale sours, I found that the more authentic my process became, the more authentic the flavors produced. The balance and aromatics improved as I turbid mashedaged hops, introduced local wild microbes with gueuze bottle dregs, etc. I wondered what the beer would be like if I stripped back the sugar-extraction to the basics? I'd brewed sour beers from malt extact before (but with beach plums, blackberries, and dark malts). This lambic recipe was nothing but dry malt extract (Pils and wheat) and maltodextrin to provide carbohydrates brewer's yeast is unable to ferment.

Brewed the day of Super Bowl 49, I opened the last bottle of the base lambic right before kickoff of Super Bowl 51. Didn't look like it had much luck in it for Tom Brady until a couple hours later... I served most of the batch at the BYO Burlington Boot Camp, the folks at the Santa Rosa edition in two weeks will be tasting and blending homebrewed dark sours. Not sure what beers we'll be using in Indianapolis this fall!

Golden Boy Lambic

Tom Brady deserves a beer.Smell – Overripe fruit, mild Brett funk comes across as hay (or is that the aged hops?). Overall mellow, but nothing off (e.g., vinegar, nail polish). At two-years-old it is still bright and vibrant.

Appearance – Crystal clear gold. Towards the darker end of gueuze, but not outside the range. White head stays around for a couple minutes, before falling completely.

Taste – Nice little lemon brightness. Mellow lactic acidity. Brett is similar to the nose, hay, mineral, and fresh soil. Relatively clean and approachable. Not much depth.

Mouthfeel – Medium carbonation, mouthfeel is fuller than usual, maybe the lack of oak tannins.

Drinkability & Notes – A lambic with training wheels both in terms of production and flavor. Not convinced those two are correlated.

Changes for Next Time – One of the nicer straight lambic blends I’ve used. Closest to Lindemans Gueuze CuvĂ©e RenĂ©, very approachable. Like many other blends Yeast Bay MĂ©lange would benefit from some dregs from whatever “fresh” lambic you enjoy.

I love splitting batches, so when the above was ready to bottle summer 2016, I racked 2.5 gallons onto peaches... lots of local white peaches from the farmer's market. They were "ugly," so I was able to get 8 lbs for $8. There is something about peaches that translates so perfectly to sour beer (as I've found previously). While the aroma is delicate compared to most berries, peaches doesn't require nearly the rate I used to shine through.

White Peach Lambic on my new 24mm lens.White Peach Lambic

Smell – White peaches, unsurprisingly. Bold, fresh, juicy. Little hits of lemon and hay underneath, but stonefruit is first, second, and third.

Appearance – Similar color to the base beer, but not as clear. A few particles of peach flesh in the glass. Head is low and doesn’t last long, a sign of lacking carbonation in this case.

Taste – Snappier acidity than the base, thanks to the acids and nutritive sugars contributed by the fruit. Has a malic acidity, brighter and sharper than lactic. Lingering in the finish are the clearest signs of lambic, earthy, citrus, mild yeastiness, and maybe a hint of vanilla.

Mouthfeel – Light body, carbonation is low even for my preferences. It allows the peach to linger though. Glad it's gotten here, I was considering reyeasting the bottles a few months ago.

Drinkability & Notes – It is amazing that peaches purchased last summer and allowed a controlled rot rather than preserved (canned or frozen) can still taste so fresh! Fantastic true-peach flavor and aroma, but the base beer wasn’t up to the challenge in assertiveness. Delicious as a peach beer, a letdown as a peach lambic. Still a good fruit choice over cherry or raspberry that would have completely dominated the delicate Brett character.

Changes for Next Time – This one didn't carbonate as quickly as I would have liked, my fault for reyeasting with ale yeast rather than wine yeast. Similar to the notes on the base beer, a more assertive culture would create potent flavors to poke through the peaches.

Not as ugly as you’d expect for $1/lb at the farmer’s market!

Gose: NEIPA Principles for Coriander

Hot-dog-water, celery, hammy… these are all descriptors I’ve heard for coriander-flavored beers. Nearly essential for wits, sometimes an accent in other Belgian beers (like those from Rochefort). Coriander, the seeds of cilantro, sometimes seem more at home in a taco than a beer, but there are two things brewers can do to ensure it imparts more pleasant aromatics like lemon, lime, and floral.

Close-up of Indian coriander.First is one I’ve touched on in previous gose recipes, use Indian coriander. It has a slightly oblong (i.e., more football than basketball) shape than the typical supermarket variety and a much fruitier aroma – Fruity Pebbles. Indian markets are also inexpensive compared to supermarkets and specialty spice stores, a 7 oz bag set me back $1.99 (compared to Amazon for $10).

Second allow coriander-yeast interaction. Glycosides and biotransformation are hot topics in hoppy beers, but they may be even more interesting for beers with fruit and spice. Coriander contains linalool and geraniol, compounds also found in hops. While unexciting in its standard form (floral and rose), yeast activity converts geraniol to B-citronellol which provides a flavor similar to lemon or lime.

"From the screening of various hop cultivars, Citra hop was selected as a geraniol-rich cultivar. In addition, it was observed that coriander seed, which can be used in beer production as a flavourant, contained not only linalool but also geraniol at high levels." The Contribution of Geraniol Metabolism to the Citrus Flavour of Beer

Wellfleet Smoked Sea Salt In the past I’ve added crushed coriander near the end of the boil or to the whirlpool, allowing it to infuse into the hot wort. That is also what was done in the study linked above. However, for this batch I drew off wort for this beer pre-boil, adding the coriander directly to the fermentor at the same time as the yeast. The rest of this batch became Loral-Hopped Funky Saison. I've found that dry hopping during fermentation is essential to the "NEIPA" character. I was hoping the same might apply to coriander!

I pitched the Right Proper house lactic culture harvested from my Quinoa Grapefruit Hoppy Sour. I didn’t have access to the high temperatures (October vs. July), and as a result sourness didn’t kick in until keg conditioning. I was recently at Right Proper brewing a collaborative smoked, juniper-infused, Norwegian farmhouse ale with Modern Times! More on that batch later...

Sodium chloride is sodium chloride, but there is nothing wrong with a story. I grew up spending summers on Cape Cod (where I still have a crate of Cranberry-Orange mead buried). Originally I’d planned to make the trip to collect bay water to dose in for salinity… but the timing didn’t work out. I had a jar of smoked sea salt from Wellfleet from my mother, close enough! Between the low dosage and low smoke-intensity I wasn’t expecting a perceptible smoke character in the beer, but sub-threshold complexity can’t hurt.

Golden Gose

Smell – Bright zesty citrus aroma. Mild graininess. Slight sulfur. I don't detect anything I would identify as coriander.

Appearance – Cloudy golden yellow. White head disperses rapidly. Not intentional, but it could pass for a NEIPA (other than the poor head retention).

Taste – Zippy lactic acidity, without the funkiness of Brett. Lots of bright fresh citrus, especially lemon (without being artificial or furniture polish). The finish has a little no-boil grainy-wortiness that I don’t mind, but it may not be for everyone. Maltiness from the Munich isn't as pronounced as I expected.

Mouthfeel – Slightly fuller than the classic versions thanks to the oats.

Drinkability & Notes – The best gose I've brewed! Refreshing and unique. The citrus from the coriander is outstanding! Sulfur aroma is the only detractor.

Changes for Next Time – Seems like this mixed culture really benefits the warmer fermentation temperature. The acidity hit its mark with extra time, but the fermentation wasn't vigorous enough to blow-off the sulfur. With the maltier grist the no-boil flavor was more assertive when young than similar all Pils/wheat beers that I've brewed - I might go for a 60 minute boil.

LODO Festbier: Split Batch Experiment

Running off the HighDO wort.My first attempt at low dissolved oxygen (LODO) brewing was lackluster... generously (I dumped the last gallon of that Pilsner). I wanted to try the intensive process again, replicating both wort production and fermentation as close as I could to what is prescribed in the second version of On Brewing Bavarian Helles. Rather than brew ten gallons of LODO festbier, I split the batch pre-boil aerating half of the wort as a control. I boiled this "HighDO" wort harder and with a copper immersion chiller. The LODO half I gently simmered and then chilled through a stainless-steel Blichmann plate chiller (although it was brazed with copper). Post-chilling I treated the beers identically from cold fermentation through spunding.

At the start of the January meeting I roped 20 members of DC Homebrewers into a blind triangle tasting of these two beers (poured from growlers I had counter-pressure filled 90 minutes prior). Only 7 of 20 (P=.52) correctly selected the odd (LODO) beer out of the three samples. That is a number perfectly consistent with random chance, suggesting that my LODO and HighDO beers were indistinguishable to the average beer nerd. Of the seven who correctly identified the aberrant sample, only one preferred it (four preferred the HighDO, and two had no preference).

After a month of drinking the two beers, I was able to select and identify the beers in my single attempted triangle test. They are similar, but the LODO does have an ever-so-slightly maltier aroma to my nose. Flavors are nearly identical.

As a disclaimer, I intended this test to explore whether my kluged-process LODO made an incremental improvement to this pale lager. I'll say "yes" if you know what to look for, but in the barest of terms. What I’d love to see is someone with a dialed-in system try the same experiment!

A single experiment can’t prove or disprove anything. That's why replication is an essential (if unsexy) part of science. Even under rigorously controlled conditions statistics like this only provide a confidence interval that suggests that the results are not due to chance. Compound this with variability introduced by brewer, brew house, tasters, conditions etc. and you sometimes produce false positive and negatives. That said, blind taste tests are the best way to insulate results from expectation and bias. Triangle tests are a pain to conduct, and put a target on you from people who can swear they can taste the difference. I have a lot of respect for what the Brulosophy folks put themselves through for data (especially after participating a couple times)! Looking forward to hanging out with Marshall in New Zealand in a couple months between talks at NZHC 2017!

Tube ringer for White Labs.As a side note, Audrey got me this tube wringer for toothpaste, but it works perfectly to extract the last few billion cells from PurePitch packages. White Labs should probably license it and sell an official version!

LODO Festbier

Smell – Clean bready malt aroma. Pleasant waft of sulfur, although a few tasters felt it considerably stronger than I do. Faint grassiness of noble hops.

Appearance – Slightly-hazy deep yellow. Dense white head sticks around until the bottom leaving patches of lacing down the sides of the glass.

Taste – Malt flavor is well rounded. Crisp, but the 5% crystal malt adds a mild honey-like sweetness. Pleasant herbal hop flavor in the finish. Clean balancing bitterness. Retro-nasal brings the appropriate lager-light-egginess back. It had a flavor that reminded me of the doughiness of a no-boil Berliner weisse when it was young, but that has faded.

Mouthfeel – Medium body with moderately prickly carbonation.

Drinkability & Notes – One of the better lagers I’ve brewed. Malty without being heavy. The sulfur is at the top of the my range, likely a result of the cold fermentation and spunding rather than the sulfite.

Changes for Next Time – Unlike my first attempt where the primary issue was double-dosing metabisulfite, this is a pleasant beer! Next time I’d reduce or eliminate the Carahell, and save the effort and brew it with the standard wort production (and warm up the fermentation towards the end)!

Brewed 11/14/16

Recipe above is the ingredients for the entire 10 gallon batch.

Made a 5L stir-plate starter. Fermented at room temperature for 36 hours, then crash chilled.

Boiled 18 gallons of water (8 distilled, 10 filtered DC) added 12 g of CaCl. Preboiled water, then added 7 crushed sodium campden tablets. Underlet mash after purging with CO2.

Mash pH 5.28.

Collected 7.5 gallons of wort as is, 4.5 aerated and left in an aluminum pot until the remainder came to a boil.

Adjusted 2.4% AA hop pellets down to 2%. Bagged.

LODO, 2.75 oz @ 60 min. 1 oz @ 10 min. Plate chiller. 1.056. Slightly sweeter, maybe could pass for maltier. A shade lighter.

Aerated, 1.65 oz @ 60 min. .6 oz @ 10 min. Immersion chiller. 1.054.

Chilled both to 46F, shook to aerate, pitched the decanted starter. Left at 48F to ferment.

11/20/16 Down to 1.032 (43% AA).

11/21/16 Started dropping 1F per day. Until it reached 43F.

11/24/16 1.024, still pretty yeasty with a small krausen.

11/27/16 1.019 (66% AA). Kegged into quadruple-purged kegs. Purged and pressurized head space. Left at 48F to carbonate. Both have some sweetness, so hopefully drops below 1.015 (73% AA).

12/3/16 Good pressure on both, 15 PSI. Removed spunding valve and began dropping 2F per day.

12/18/16 Attached to gas and dumped yeast from both. FG 1.013 (76.8% attenuation) on the LODO, 1.012 (77.8%) on the HighDO.

Borrowed Wort: Commonwealth Sour Brown

When I set out to visit Commonwealth Brewing Co. in Virginia Beach to collaborate on a sour brown, I tossed a sanitized carboy in the trunk. I brought home three gallons of wort and pitched my own microbes (Omega Lacto Blend and bottle dregs) in addition to their house ale yeast.

With all of the effort many brewers put into wort production for sour beers, I thought it was worth noting how little my "version" has in common with the wort that stayed at Commonwealth. Especially for sour beers, so much of the final character is dependent on the microbes, barrels, blending, and in this case (lack of) fruit! I'm not saying wort production is irrelevant, but getting the right fermentation is much more important than whether the beer is 10% or 20% wheat!

Home-Fermented Commonwealth Sour Brown AleThere are still a few bottles of both variants (Penthesilia and Hippolyta) available at the brewery's tasting room if you want to taste the beer (or steal the microbes)!

Home-Fermented Sour Brown

Smell – Red fruit, dusty Brett, and caramel malt. Vibrant, no oxidation. Faint alcohol as it warms.

Appearance – Deep clear brown with red highlights. The off-white head displays impressive retention for a sour beer.

Taste – Bright lactic acidity. Cherry and blue cheese funk from the Brett. Slight grape Fruit Roll-Up. Minimal sweetness, but some caramel malty-depth.

Mouthfeel – Light without being tannic or desiccant. I like a bit more heft.

Drinkability & Notes – Not hugely interesting, but a pleasantly drinkable dark sour that showcases a variety of classic Brett funk with balancing acidity.

Changes for Next Time – Shouldn’t come as much surprise, but I think this is a good illustration of why trying to “clone” commercial sour beers is a fool’s errand. Even with literally identical wort you can't do it without the other pieces of the process!

Staff of Ra (Sour Brown with Coffee)

Given the less-than-exciting trajectory of this batch as it approached packaging, I diverted a gallon to try a coffee-infused version. I know, listening to the so-called expert of American Sour Beers this might seem like a bad idea:

“The bold coffee and chocolate additions that work so well in big sweet stouts do not succeed when combined with a dry and sour base.”

My opinion softened after I split a glass of Lervig CafĂ© Sur, a unique sour pale with coffee while in Norway. I only risked a gallon, adding .5 oz of uncrushed Ceremony Thesis coffee beans (the same I used for this Hoppy Blonde) for less than a day…

Home-Fermented Commonwealth Sour Brown Ale with CoffeeSmell – The coffee adds a fresh toasty-roasty aroma that combines with the fruitiness, covering the majority of the funk (leaving just a bit of dust). Slight “green bell pepper” of oxidized coffee, it has faded from where it was a few months ago.

Appearance – Some light really brings out the red! Head retention is slightly less, but that may be thanks more to reusing the glass rather than the coffee beans.

Taste – The coffee is a good match for this beer, although they aren’t a fresh as I would have liked. It reduces the perception of the Brett. Acidity is similar. Coffee would be a waste of a more interesting base beer. I'd put it in the same category as dry hops for a sour, not what I would add to my favorite base beer.

Mouthfeel – Similar to the straight version.

Drinkability & Notes – The coffee adds some interest to what is an otherwise unremarkable base beer. This isn't exactly the right combination, but it is something I'll experiment more with in the future.

Changes for Next Time – A paler base beer might work better given the additive power of the dark malts and beans. Alternatively, a coffee with more dark fruit might have been a better match for a dark sour.

Courage RIS (No Brett): Tasting

Courage Russian Imperial Stout Clone: No Brett or Oak.
The continuation of my Christmas eve tradition of drinking homebrewed Courage Russian Imperial Stout was beginning to look in doubt. After 2015 I was down to three bottles, so February 2016 I rebrewed a tweaked 10 gallon batch (recipe). Originally the plan was to give half the wort to my friend Scott, but when his plans changed at the last minute I split the batch with myself instead: half clean, half with White Labs Brett claussenii and oak spheres.

The funky-oaky half is ready to bottle this week. As with the original batch from 2007, once the gravity reached 1.020 I transferred the beer to a clean fermentor with one campden tablet (sodium metabisulfite) per gallon. This additional 20% apparent attenuation from Brett isn't guaranteed. Mike Karnowski, the brewer/founder of Zebulon Artisan Ales (and author of Homebrew Beyond the Basics), homebrewed a similar recipe a couple years ago and split it between five commercial Brett strains, but didn't see significant attenuation from any of them (not a bad thing) - I got to taste a sample of each at a bottle share while I was in town for the Asheville Homebrewers Conference!

Courage RIS 2016: Base

Smell – Expressive clean roasted nose. Charred cocoa, fresh bready malt, a hint of ethanol. There is a subtle dark fruitiness from the candi syrup, but not nearly the intense-raisin that many year-old dark-crystal-malt dependent imperial stouts fall. No noticeable oxidation. No hop aroma, unsurprising given the single early Columbus addition.

Appearance – Beautiful, opaque, black body. Voluminous mocha head (bigger than I like to see on what should be a low-carbed beer). Great retention despite the snow landing on it.

No better day than a snowy day for Imperial Stout!Taste – Flavor is a delicious blend of 85% cocoa chocolate bar, richly toasted malt, and subtle English ale fruitiness. Enough bitterness (hop, roast, alcohol) to balance the plum-sweetness in the mid-palate. It doesn’t taste like a 1.040 FG beer, but then it may grow sweeter as the bitterness drops off with time.

Mouthfeel – Thick, coating, rich. Carbonation is elevated from my preference (and the 2.1 volumes I targeted), but I wouldn’t call it over-carbonated in general beer terms.

Drinkability & Notes – Surprisingly drinkable for a beer this big in alcohol and sweetness. It maintains a fresh malt flavor from the Maris Otter and amber malts that plays off the firm Black Patent roast wonderfully. Without Brett the malt is much more in focus.

Changes for Next Time – This is it for me other than the carbonation (which is easy enough to swirl out). As big as it needs to be, with an intense maltiness that I don't think would be possible in a smaller stout. At 9% a 12 oz bottle is a reasonable serving, something I can't say for the many commercial stouts that don't achieve this flavor-saturation with 12-16% ABV!

Hopefully the next few years are kind to the remaining case and a half!

I drank my third-to-last bottle of the original on Christmas eve. Not much had changed since last year so it didn't seem worth writing up the full tasting notes. Carbonation was still pleasantly low, big dark fruit, gentle funkiness, no sign of impending oxidized-doom for the last couple bottles!

One of the last glasses of one of my favorite beers.
