Rye whisky is a whisky distilled from a mash containing rye. It is mainly produced in North America. In the United States law requires that the grain mash contains at least 51 % rye in order to be labelled as rye whisky. In recent decades with the advent of single malts and the whisky market becoming more diverse rye whisky has also made a comeback. In the original recipes of many classic whisky cocktails, such as the Manhattan Cocktail, rye is used as ingredient in the form of whisky.
