Single Bourbon Barrel Aged 2 Tun is their Ale of the 2 Tun Imperial Stout aged in a bourbon barrel since 2012. The beer will be available in draft only and could be all gone within days after the initial release.
From Head Brewer Greg Filippi's tasting notes:
The whiskey character is strong up front and dominates the aroma, but beneath it lie the familiar chocolate and espresso notes of the stout. Whiskey shines through again as the beer crosses the palate, but quickly gives way to smooth, silky chocolate. That chocolate lingers in the finish, dancing with the sweet bourbon in perfect form, the way only years together can produce.For the fortunate few who have sampled the beer, the excited reactions have been unanimous, and the Hermitage team is looking forward to having the public have their opportunity to come out and try the beer.
