Dear God, a thread on beer without my input? Beer is possibly my passion (yet I haven't touched a drop since Jan, so hold the alcoholic comments thanks).
There are so many varieties of beer you can't possibly say, 'I don't like beer'. You just haven't found the right one!
English ales should be served at cellar temperature, as whoever copied the CAMRA guidelines said. And yes that makes them a bit warm. However have you noticed that if you go in an English pub and ask for a bottle of traditional ale, it will more often than not come out of a fridge.
Lagers should be served cold here though. I don't recall ever being served a pint of warm lager (apart from when some dozy bar maid puts it in a warm glass).
America, contrary to popular belief, produces some really interesting beers. If you just manage to think past their more prolific brands (that whilst being 'American' are more often than not brewed in the country they're sold in), the country has a thriving micro-brewery sector, producing some popular brews that are very unlike what we would think of as American beers.
Novella, if you still care - yes I have made beer in the past. Lots. And wine (and no, I'm not an alcoholic!). Oh and the guy who edits the CAMRA bible also wrote a book - The Complete Guide to World Beer (Roger Protz). A very interesting read, takes you through the brewing process, the world's beers, the culture of drinking and the history of the brewing industry.
