draft beer?

Tomeka Hameen: The headache

Chanda Wittwer: Draft or draught beer is drawn directly from a keg. Other than that, there is no difference. Bars and taverns will usually sell it for less than a bottle or can because they buy it cheaper. I have had issues with draft beer in the past because some pubs do not clean their lines well and this usually leads to a lousy tasting brew and/or a hangover.

Emerita Sciandra: Draft beer is any beer served from or conditioned in a cask or pressurized keg...this includes cask ale, keg beer, bottled and canned beer. "regular beer" is none of the above :)

Luke Creitz: Draft beer unlike bottled or canned beer is not pasteurized and in canned or bottled beer no further fermentation takes place, where as in draft beer fermentation continues and left without refrigeration spoils faster.
