What characterizes sour cocktails?

Sour cocktails are characterized by a balance of sour and sweet elements. This balance is typically achieved through the combination of a sour ingredient, such as fresh citrus juice (like lemon or lime), with a sweet component, which could be simple syrup, liqueurs, or sweet vermouth. This interplay creates a refreshing drink that is both tart and sweet, making it a popular choice in cocktail crafting. The balance between these elements is crucial in achieving the desired flavor profile and overall enjoyment of the cocktail.

In contrast to the other options, sour cocktails are not typically defined by high alcohol content or low sweetness, nor are they solely composed of sweet ingredients or focused solely on herbal flavors. Those characteristics speak to different styles of cocktails or drinks entirely, showing how the intricate balance of flavors makes sour cocktails unique and distinct.
