Last night I enjoyed my yearly bottle of 120 Minute Imperial IPA from Dogfish Head Craft Brewery. Each year I somehow manage to find one or two bottles of the limited release beer. The beer totally assaults the senses (in a good way). Clocking in at an IBU of 120 and an alcohol by volume level of 15-20% (probably 18%, according to the brewers website), this beer leaves an great impression. The warmth created by the alcohol is more similar to drinking a brandy than to drinking a beer. Highly recommended.
