Lager.

Johan Almenberg and his wife Anna Dreber, of the Stockholm School of Economics, and Robin Goldstein, author of 'The Beer Trials' and the upcoming book 'Blind Taste' have analysed 'lager tastes' only to discover, that by and large, lager drinkers are unable to distinguish between brands.
Who can be surprised? Lager, to me, always tastes of wet bread. Although I drink very little beer - I must admit to being 'a bitter man.'
