Rye whiskey, in the American sense, is a whiskey produced in the United States from a grain mash containing at least 51% rye. Under 27 CFR Part 5 it must be distilled at no more than 160 proof and entered into new charred oak at no more than 125 proof. 'Straight rye' requires at least two years of maturation. Canadian whisky is often colloquially called 'rye' in Canada, but the Canadian regulatory definition is different — Canadian whisky may contain little or no actual rye grain. Rye was the dominant American whiskey style before Prohibition (Monongahela and Maryland styles) and has experienced a 21st-century revival driven by classic cocktails.

Mash Bill and Flavour
American rye must contain at least 51% rye grain, typically alongside corn and malted barley. Rye contributes spice, dryness, and a peppery quality distinct from corn-led bourbon's sweetness. High-rye expressions (95% rye for MGP Indiana stocks, used by many craft brands) showcase the grain's character more aggressively than mid-fifties recipes such as Old Overholt.
Pre-Prohibition Heritage and Revival
Before Prohibition, rye whiskey from the Monongahela Valley (Pennsylvania) and from Maryland dominated American whiskey production. Prohibition (1920–1933) and subsequent industry consolidation reduced rye to a tiny share of the market by the late 20th century. The 2000s craft cocktail revival — emphasising rye's central role in the Manhattan, Sazerac, and Old Fashioned — drove a major resurgence in rye production from major and craft distilleries.

Frequently asked questions
Is American rye the same as Canadian 'rye'?
No. American rye must contain at least 51% rye grain in the mash bill. Canadian whisky is called 'rye' colloquially in Canada for historical reasons but the regulatory definition allows any grain composition. Some Canadian whiskies (Alberta Premium, Lot 40) are made from 100% rye, but many contain little to no rye grain.
Why is rye associated with the Manhattan cocktail?
Pre-Prohibition American whiskey was predominantly rye, and the classic Manhattan recipe (rye, sweet vermouth, bitters) was codified in late-19th-century New York bartender's manuals. After Prohibition, bourbon often substituted rye in Manhattans; the contemporary cocktail revival has restored rye as the traditional base.
