A whisky distillery is a facility where whisky is produced through a series of processes that include mashing, fermentation, distillation, and aging. The main ingredients used are water, grains (such as barley, corn, rye, or wheat), and yeast. Each distillery often has its unique methods and recipes, contributing to the distinct flavors and characteristics of the whisky. After distillation, the spirit is typically aged in wooden barrels, which can be made from oak. This aging process allows the whisky to develop its flavor and color over time. Distilleries may also offer tours and tastings, providing visitors with insights into the whisky-making process and the history of the distillery.
