Draft beer, often referred to as draught beer, is beer served from a keg rather than a bottle or can. It is typically dispensed using a tap system, which allows for a fresh and carbonated pour. Draft beer is popular in bars and restaurants because it can be more economical and environmentally friendly, reducing packaging waste. The flavor of draft beer can be influenced by factors such as the type of keg, the tap system, and the glassware used. Many breweries offer a variety of draft options, allowing consumers to enjoy different styles, including lagers, ales, and stouts.
