Even though the entire world is filled with beer lovers, one thing is universal, many beer lovers prefer draft beers. Draft beers are beer that are held in a keg, and dispensed through beer taps. Beer taps work like a sink's faucet. In fact, depending on location, a "tap" may be a "faucet", "valve" or "spigot". Many people prefer draft beers because pouring from a beer tap provides a fresher taste, and the right amount of head. The beer from the drafts are generally held in a keg, or in a kegerator.
A keg is a metal barrel container used to hold drinks. Generally bought for beer, kegs are a mainstay of many drinking parties and bars. It is generally the most cost effective and environmentally friendly way to get lots of people drunk. Kegs have a two way valve in the center of the top of the container that is used for filling, cleaning and tapping the insides. A kegerator is a special fridge, outfited to hold both a keg and beer tap so you can despense cold, fresh beer.
