Grain whisky normally refers to any whisky made, at least in part, from other than 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. Whisky made only from malted barley is generally called "malt whisky" rather than grain whisky. Most American whiskey and Canadian whisky whiskies are grain whiskies.
In both countries, grain whisky is typically distilled in a continuous column still in a manner that results in a higher percentage of alcohol by volume (ABV) but a less flavourful spirit than that derived from a pot still. As a result, grain whisky is seldom bottled by itself in either country but is instead used primarily for blending with malt or pot still whisky to create Blended whisky, which now account for more than 90% of both countries' whisky sales. The comparative lightness of the clearer, more-neutral-flavoured grain whisky is used in blends to smooth out the often harsher characteristics of single malts and single pot still whiskeys. Occasionally well-aged grain whiskies are released as single grain whisky if made at one distillery or blended grain whisky if combining spirits from multiple distilleries.
Outside Ireland and Scotland, the use of continuous column stills and the use of a non-barley mash are not so closely associated with the production of "light" whisky (whisky with little flavour due to distillation at a very high ABV). For example, nearly all American whiskey is produced using column stills, and all American whiskey that is labelled as "straight whiskey" (including straight Bourbon whiskey and rye whiskey) is required to use a distillation level not exceeding 80% ABV. In the United States, whiskey produced at greater than 80% ABV is formally classified as "light whiskey" and cannot be labelled with the name of a grain or called malt, bourbon or straight.
