Description
Sours are one of the late 19th century foundational cocktails from which hundreds of others have been developed. The basic form of a sour is a spirit combined with sugar or sweet liqueur and a citrus juice instead of the bitters employed in the Basic Cocktail.
The basic sours are named simply for their base spirit: whiskey sour, gin sour, rum sour, et cetera. From this sturdy base, great heights of sophistication are possible. It's important to master the foundation first.
