The Presbyterian is a whiskey-based highball American cocktail, likely originating in the mid-20th century. It is made with a base spirit of whisky – which could be Scotch, bourbon, or rye whiskey – combined with equal amounts of ginger ale and club soda.
The Presbyterian resembles other highballs such as the Moscow Mule and the Dark 'n' Stormy, but with whiskey as the defining ingredient.
The drink’s name may allude to temperance influences in Presbyterian church communities, suggesting its popularity as a lighter, more refreshing way to enjoy whiskey.
The cocktail is typically built in a tall highball or Collins glass with a large ice cube, and garnished with citrus.
Note: The Presbyterian is sometimes suggested to be the namesake of the Brandy Old Fashioned Press, a Wisconsin cocktail that lightens its flavor profile with club soda.
