Grain whisky ordinarily refers to any
whisky made, at least in part, from
grains other than
malted barley, such as whisky made using
maize (corn),
wheat or
rye. Grain whiskies may also contain some malted barley (and are required to if produced in
Scotland). Whisky made from only malted barley (or primarily from malted barley) is typically called
malt whisky rather than grain whisky (although barley is a grain). Most
American whiskeys and
Canadian whiskys are grain-based.
