This yearâs release of B-Bomb is aged in 8â12-year-old American Oak bourbon barrels and is a blend of 9, 12, and 24-month old barrel-aged Winter Ale. B-Bomb achieves distinct bourbon, oak, cacao, leather, toffee, and dark coffee notes from its extended barrel aging and barrel blending. Each barrel contributes a different note, and combining each barrel to create a coherent tone is a distinct art and true pleasure. Please do enjoy this unique barrel-aged ale today but know that B-Bomb will age gracefully for at least another 5 years. Donât Be Afraid To Be Abominable.
