Whiskey is a broad category of distilled spirits made from fermented grain mash, including barley, corn, rye, and wheat. It encompasses several styles, such as Scotch, Bourbon, Rye, and Irish whiskey, each with its distinct flavor profile. In the context of alcohol and cocktails, whiskey is celebrated for its complexity and depth of flavor. It can be enjoyed neat, on the rocks, or as a key ingredient in classic cocktails like the Old Fashioned, Manhattan, and Whiskey Sour. Whiskey's rich, nuanced flavors can range from smoky and peaty to sweet and caramel-like, allowing it to pair well with a wide variety of mixers and other ingredients, including bitters, citrus, and sweeteners.
