What is Canadian Whisky?
Canada's regulations specify only one rule for producing Canadian Whisky - it has to be mashed, distilled and aged for at least three years in Canada.
Canadian Whisky vs. American Whiskey?
The U.S. has stricter rules about how Whiskey can be made/marketed. Canadian Whiskies often hit proofs 190, meaning a stronger, but less flavorful foundation, resulting in drams that are lighter, sweeter and smoother than American Whiskeys.
How's it made?
Commonly it is made from several different grains, corn and wheat used as primary grains in Canadian Whisky production. Each grain is usually fermented, distilled and aged separately. They're only combined together at the very end.
