Tun is a traditional container used for storing liquids, particularly in the production of alcoholic beverages like beer and wine. Typically made from wood, metal, or plastic, tun can vary in size and shape, depending on its intended use. In the brewing process, a tun is essential for mashing grains, allowing enzymes to convert starches into sugars. This step is crucial for creating the base for fermentation, where yeast transforms sugars into alcohol. Tuns are also used in distillation processes for spirits, highlighting their importance in the beverage industry.
