Pub draught is a type of beer that is served from a keg or cask. It is usually unfiltered and unpasteurized, which gives it a unique flavor and texture. Pub draught is also known as cask ALE, real ALE, or cellar beer. It is typically served at room temperature and is often served with a hand pump. Pub draught is popular in the United Kingdom and is becoming increasingly popular in other parts of the world.
