What is a draft beer and how does it differ from other types of beer?

A draft beer is beer that is served from a keg or cask, typically at a bar or restaurant. It is dispensed using a tap system that delivers the beer directly to the glass. Draft beer differs from other types of beer, such as bottled or canned beer, in that it is typically fresher and has a smoother, creamier texture due to the carbonation process.
