Double Barrel Derivation - Mizunara Oak
Side Project Brewing

Double Barrel Derivation Mizunara Oak is our first foray into some of the more exotic woods available to age spirits and now beer in. As most of you know, we have a great friend in Drew Kulsveen from Willett, and he offered up his only 2 barrels of this Japanese oak for us to double barrel-age Derivation in. Mizunara oak is one of the rarest and most expensive oaks in the world. Drew used this Japanese oak barrel to finish a special project, then allowed us to have them. We chose 2 oak barrels of our O.W.K. recipe which were laid in Willett 6 year Family Estate bourbon barrels on June 10th of 2020. On December 6th of 2021, we double barreled the 18 month old imperial stout into the Willett Mizunara oak casks for their second aging and finishing.
