Welcome the Most Most Premium, an 11.5% Imperial Stout that is rich, heavy and thick. This roasty, toasty, chocolatey, bourbony, woody, and delicious brew is one to save for a rainy dayIn their words: Blacker than the uncaring hearts of the Czars of Russia, richer than their estates, more decadent than their palaces, and larger than their empire, this bourbon barrel aged imperial stout is truly MOST Most Premium.
