Style: American Imperial Stout

Alcohol by volume (ABV): 20.59%

Availability: Limited (brewed once)

Notes / Commercial Description:
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.

4.32/5  rDev -2.3%
look: 4.25 | smell: 4.75 | taste: 4 | feel: 4.25 | overall: 4.5

500 mL bottle poured into a snifter.

Pours black with a fairly aggressively carbonated half-inch head dissipating quickly into a thin dark brown lacing.

Nose: Incredibly decadent. Rich layers of vanilla and bourbon along with a strong dark fruit presence. A bit boozy at the end.

Taste: Boozy bourbon up front followed by a ton of vanilla. Quite a bit of heat in the finish - WAY more bourbon forward than fundamental observation. This could definitely use a good amount of time in the bottle to calm down, but has incredible potential.

Feel: Full-bodied, pretty high carbonation for the style.

Sampled on 4-6-19. Pours a very dark brown/black with minimal head. Not a lot going on in the smell department, maybe a hint of vanilla and booze. Initial sip and the booze hit my throat really hard. Was not expected Black Tuesday. Following tastes were better, as my body must've been ready for the high alcohol and it wasn't prevalent. Faint vanilla on the back end, but other than that, not really impressed. I'd take the regular any time.

Very boozy. I think even more so as it warms up. Def get multiple barrels out of the taste. I def rec. letting it age a little and going back at it again down the line.
