Sour Mix

Sour mix is a liquid ingredient used in many cocktails, particularly ones like margaritas and margarita-style drinks. It combines citrus juice—mostly lemon and lime—with sugar or simple syrup to create a balanced, tangy, and sweet flavor. Commercial sour mix is typically pre-made, offering convenience, but it can also be made fresh at home. It enhances beverages by adding acidity and sweetness, helping to brighten other flavors in the cocktail. The mixture is stored refrigerated and is an essential component for bartenders to quickly prepare a variety of sour-style drinks.
