All whisky drinkers know about Scotch, but Canadian whisky has also been gaining popularity in recent years. In addition to their countries of origin, there are some significant differences between the two.
Scotch must contain mostly malted barley – other cereal grains are optional – and must be matured in oak barrels, in Scotland, for more than three years. Scotches labeled "single-malt" are 100% barley, and if European whisky has "glen" in the name, you know it came from Scotland.
Canadian whisky, on the other hand, is made by Canadian workers in Canada using Canadian grain – often wheat, corn, and some rye. Like Scotch, the spirit must also be aged for at least three years, but due to the relatively more flexible regulations, Canadian whiskies have become known for carefully crafted blends.
