No Penguins were harmed in the making of this beer; some humans did get very, very cold though! Tactical Nuclear Penguin's name comes from the amount of time this beer spent exposed to extreme cold. This beer was initially double barrel aged for 14 months; maturing in the deep, rich oak of Scottish whisky casks. After this epic maturation the beer was then frozen, then frozen again, then frozen again.This is an extremely strong beer, it should be enjoyed in small servings and with an air of aristocratic nonchalance. The "Penguin" comes wonderfully adorned with an old-school bottle stopper that allows the stout aficionado to enjoy in moderation.
