Whisky is a distilled alcoholic beverage made from fermented grain mash. The grains used can include barley, corn, rye, and wheat. The production process involves mashing the grains, fermenting the mash, distilling the liquid, and aging it in wooden casks, typically made of oak. The aging process contributes to the flavor and character of the whisky. There are several types of whisky, including Scotch, Irish whiskey, bourbon, and rye whiskey. Each type has its own unique production methods and flavor profiles. The alcohol content of whisky usually ranges from 40% to 50% by volume, making it a strong spirit enjoyed in various ways, including neat, on the rocks, or in cocktails.
