What a find ..

[freddie]

warm beer versus cold beer i think has much to do with the color of the beer being consumed, probably like wines.
The darker ones can be served at warmer temps...the lighter the color the cooler the better i find

As a general rule you've got it spot on. However, just to confuse things, there are some light coloured British 'real ales' which look just like lager (Badger's Tanglefoot is a good one) but shouldn't be served too cold. On the other hand a dark beer which wouldn't have been served cold years ago is Guinness, but now it's served through a chiller, and if that wasn't cold enough they even do a version called 'Extra Cold'. I love Guiness, but don't like it too cold, so I always used to buy a bottle off the shelf, (or a bottle of light ale, pale ale or brown ale.) But now those days have gone, and the only bottled beers you can buy in a pub are lagers and alcopops served from a fridge. I'm shivering just thinking about it !
