Canadian rye whisky is a Canadian grain whisky, historically named for its rye content, usually blended and column-distilled.
Light and smooth is the brief, so a gentle blend of any origin does the job. An American rye brings noticeably more spice and heat, which changes the drink rather than standing in for it.
American rye whisky
American rye is at least 51% rye by law, and it is drier, more peppery and fuller. A cocktail written for light Canadian sharpens up with it; pulling the measure back by about a quarter is one way to keep the balance, though that is a serving suggestion rather than a rule.
Canadian practice is to distil the base and the flavoring whiskies separately and blend them afterwards, which is the opposite of the American approach of mashing the grains together first. The base is usually a light column-distilled corn whisky and the flavoring share is small, which is why the category is smooth by design rather than by accident. Canadian law also allows up to 9.09% of the blend to be something other than Canadian whisky, often bourbon or wine. That allowance is part of why a bottle can taste sweeter and rounder than its grain bill suggests.
