I think Peter is being a 'real ale snob', red. He's probably a member of CAMRA as well
And unless I misunderstand, all beer in Germany (like everywhere in the world other than England, I think) is carbonated and therefore would be considered 'lager' by the real ale snobs in England.
Nothing wrong with real ale, of course. Had 3 lovely pints of the stuff down the Jolly Farmer last night. But lager is equally tasty and I don't really get being snobby about beer.
