Berkshire Samuel Adams Cask Finished Bourbon, 43%

One of a series of Berkshire bottlings done in barrels used to age craft beers; this one aged the massive (29%!) and complex Samuel Adams Utopias. The beer barrel adds a depth to Berkshire's usually brighter character, a rounded and full sweetness with rum and fruit notes. There's heat and youthful sweetness, and a pleasing fullness that grows toward the warming finish. A nice twist on the usual bottling. (Massachusetts only)
