Canadian whisky is whisky made in Canada; by law it must be aged there at least three years in a wooden barrel of not greater than 700 litre capacity. Most Canadian whiskies are blended multi-grain whiskies and are usually lighter and smoother than other whiskey styles. These are also called "rye whisky," in Canada though the American definition of "Rye Whiskey" prevents them from being so labeled in the USA. Although rye is often a primary component in Canadian whiskies, the use of rye is not dictated by legal standards.
