My favourite beer by a country mile is Augustiner Munchen, used to be about a €1 a bottle back in 1998 when I spent a summer in Munich. You can drink this stuff all day and night without fear of a hangover. If you ever hit the Oktoberfest, check their tent out.
Had the pleasure of drinking it again recently in the Bull & Castle up by Christchurch during their Oktoberfest. Hoping to pick up a tray of it soon.
