Grain whisky normally refers to any whisky made, at least in part, from grains other than malted barley. Frequently used grains include maize, wheat, and rye. Grain whiskies usually contain some malted barley to provide enzymes needed for mashing and are required to include it if they are produced in Ireland or Scotland.[1][2] Whisky made only from malted barley is generally called "malt whisky" rather than grain whisky. Most American and Canadian whiskies are grain whiskies.
