What is "whiskey"?

Whiskey, also known as whisky, is a distilled spirit that is made from fermented grains, such as barley, corn, rye, or wheat. The grains are mashed, fermented, and then distilled to create a clear, high-proof spirit that is then aged in oak barrels. The aging process gives whiskey its distinct color and flavor, with notes of caramel, vanilla, and wood. Whiskey is produced in many countries around the world, including Scotland, Ireland, the United States, Canada, and Japan, and comes in a wide range of styles and flavors. Single malt whiskey, made from 100% malted barley and distilled in a single distillery, is highly prized by connoisseurs, while blended whiskey, made by blending different whiskies, is more common and widely available. Whiskey is often consumed neat or on the rocks, but can also be used in cocktails and mixed drinks.
