With an abv of 32%, Tactical Nuclear Penguin beats the previous record of 31% held by German beer brand Schorschbraer.

The beer began as a 10% imperial stout 18 months ago. The beer was aged for eight months in an Isle of Arran whisky cask and eight months in an Islay cask. The beer was then stored at -20 degrees for three weeks to get it to 32%.
