Often considered the lightest and friendliest of Whiskeys, Canadian Whiskey is most often corn-based, but a small portion of rye is often also added to the mash bill in order to enhance flavor. Because of the prevalence of this practice, Canadian Whisky is often referred to as Canadian Rye or Rye Whisky, though one shouldn’t confuse it with American Rye Whiskey, which must have a mash bill made from at least 51% rye grain. Canadian Whiskey must be entirely produced in Canada, including an aging period of three years in oak barrels.
