Spent ten days in Gloucestershire-Cheltenham area last spring. Got LOTS of real ale inside me. No hangovers or big heads involved, maybe because of the real ale, maybe because of the surprisingly superb food served alongside. Here in USA I brew my own, but there's lots of good micro ales available. Mass market American beer is actually brewed to very exacting standards. Being mass market, though, they can't get too heavily onto distinctive flavors. After years of homebrew, the MM beers just taste light and sweet to me, but they're great cold quenchers when you're hot and sweaty.
