No beer is meant to be served at room temperature (70 degrees). But many English-style ales are meant to be served at cellar temperature, which is 50-55 degrees. This might seem warm to Americans who are used to drinking their beer ice cold (30-40 degrees). Cold beer is an American invention to mask the fact that American macros have no flavour! When you serve beer that cold it numbs your taste buds, and you can't taste anything. Do yourself a favour and drink your ales at cellar temperature. You might be amazed at what you're missing!
