Homonym: Sours (Fermentation)
Sours are a category of cocktails known for their tart and tangy flavor profile, typically made with a base spirit, citrus juice, and a sweetener. The most common base spirits used in sours include whiskey, rum, and vodka. The addition of citrus, usually lemon or lime juice, provides the signature sour taste, while sweeteners like simple syrup or agave nectar balance the acidity.
One of the most famous examples of a sour cocktail is the Whiskey Sour, which combines bourbon, lemon juice, and sugar. Sours can also be served shaken or blended, and they often include a frothy texture when egg whites are added, creating a smooth finish.
