A golden, smooth ale from Strangeways Brewery in Manchester, England. The cans contain a small plastic device (which they call the "Draughtflow System") that floats in the ale. This widget mixes air into the ale when the can is opened, giving it a creamy head when poured and allowing the brewery to reduce the level of carbonation. It's not quite the same as drinking a hand-pulled beer but it's close.
From my experience, this beer is best served chilled but not ice-cold, and always in a glass. Recommended background music: Strangeways, Here We Come by the Smiths.
