I like a pint at about 4% alcohol by volume, pretty well standard for most of the local drinkable Bitters here in Manchester. As I understand it after prohibition (agued fore by the Kennedys, who then proceeded to buy up as many of the breweries as they could get their hands on, and then argued for its abolition) the maximum strength of beer was set at the weakest level (3.2% I think). As I understand it, things have changed with imported and local micro-brewed stronger beers available. In continental Europe it's hard to find a beer bellow 4.7%.
