Draft systems are methods used to transport liquids, such as beer or soda, from a storage container to a serving tap. These systems typically consist of a keg, a series of tubes, and a tap, allowing for efficient dispensing while maintaining the beverage's quality and carbonation. In commercial settings, draft systems are popular because they reduce waste and provide a fresh product. They can be found in bars and restaurants, where kegs are connected to taps for easy access. Proper maintenance of these systems is essential to ensure optimal performance and taste.
