please name this "British Beer"
You're talking complete and utter shite :D
The average joe in this country goes to the pub and drinks a pint of stella, carlsberg, fosters.
Most popular bottled beers - things like becks, budweiser.
The only "true" British beers are the proper brown ales, like Fullers London Pride. Or Boddingtons. Not very popular at all except with old people.
Stella Artois has been the best selling lager in Britain for a while now but recently Carlsberg overtook it
