Sour

A sour is essentially a simplified Punch, consisting of usually just three ingredients:

• Spirit
• Sweetener
• Sour

The sweetener can take the form of sugar or simple syrup, or it can be a liqueur of some sort which has a prominently sweet flavor.

The sour is usually either lemon or lime juice, but can technically be any high-acid ingredient which would lend the same character.

While at one time considered a mixed drink category all of it's own, in more recent times it appears to be seen as a sub-category of the Cocktail. Some common sour style drinks are:

• Cosmopolitan
• Daiquiri
• Margarita
• Sidecar
• Whiskey Sour
