We’re thrilled to share the extraordinary details of our first Level III #StasisProject release, #FundamentalTheorem.
In our perpetual search for knowledge and near-fanatical drive to explore and experiment, for our Fifth Anniversary we sought to create a colossal, bourbon-soaked rendition of #FundamentalObservation — the lightning rod Bourbon Barrel Aged Imperial Vanilla Stout which has defined our first five years.
Where #FundamentalForces was a study in altering the base recipe with mountains of additional fermentable sugars to achieve an imposing ABV, Fundamental Theorem remains faithful to the FO recipe and instead becomes a testament of time, of spirit, and of the barrels themselves.
Fundamental Theorem began as a small reservation of the best tasting barrels from the third batch of Fundamental Observation. Over the last two years this same initial liquid has been guided through four successive sets of bourbon barrels, soaking in the bold bourbon spirit and pulling the charred caramel-vanilla essence from the oak as the liquid expanded and condensed throughout the seasons.
At an otherworldly 20.59% ABV, this beer is not for everyone. It’s all bourbon, all barrel, and all elegantly aged and finished with a blend of velvety Madagascar and soft, floral Tahitian vanilla beans.

Pours black, no head. Scent is full, boozy. Sharp. Taste is full, boozy, grainy, quite rediculous on the boozyness and alcohol - sure, it's high, but other beers of this ABV aren't nearly as boozy . Roastuy, has a good essence, but is quite honestly been ruined by the stupid amount of boozyness.

Bottle thanks to BillyT. It pours darkest brown to black with a minimal head. The aroma is slick, oily, intense, dark roasted malt, charred, chocolate cake, vanilla, bourbon, toasted coconut, some umami, toffee and vanilla fudge. The taste is slick, oily, boozey, punchy, dark roasted, rubbing alcohol, bourbon soaked oak, chocolate, nutty, praline, hazelnut, tannin, rawness, chocolate bourbons, spicy and leathery tannin with a drying finish. Fulsome body and fine carbonation and drying feel. Intense and pretty intense.

Still a maaaaasive booze bomb, that nose is like at least a double cask strength rubbing alcohol killer, flavor is pretty good actually but it attacks you like a moonshine burner. Maybe for you Art D.

Glad I was warned about this one. Ridiculously boozy and alcoholic. Undermeath it just traces of vanilla, but it's so hot and bourbony that you really have to look for it. Sweet chocolatey flavours, bourbon and bourbon. Not really that good.

Powerful tasting at Salesforce, bottle; 2019; 20.59% ABV
Still and thick pour, black colour with no head. Huge aroma, dark malts, leather, chocolate, tar. The mouthfeel is very syrupy; lots of dark sugars, but also a lot of booze; dark chocolate flavour, nut, loads of bourbon, with very warm final.
Respect to the unique exercise in brewing.

500ml at Sales Force (thx, Robert B.!). Appearance: almost black with a weak dark brown head. Aroma: bourbon, dark cherries, booze. Taste: along the same lines, very boozy, but the ABV is quite nicely integrated. Overall: good one.
