Just to point out that whiskies made in Canada, Japan, Scotland, England and Wales are called "whisky".
Whiskeys produced in Ireland and the USA are called "whiskey".
So in the two main whisky areas - Scotland and Ireland - whisky is spelt "whisky" and "whiskey" respectively.
The word "whisky/whiskey" comes from the Irish Gaelic "uisce" and Scottish Gaelic "uisge" meaning "water".
By Canadian law Canadian whiskies must be produced and aged in Canada, be distilled from a fermented mash of cereal grain, be aged in wood barrels with a capacity limit of 700 litres (185 US gal; 154 imp gal) for not less than three years, and "possess the aroma, taste and character generally attributed to Canadian whisky".The terms "Canadian Whisky", "Rye Whisky", and "Canadian Rye Whisky" are legally indistinguishable in Canada and do not require any specific grain in their production. Canadian whiskies may contain caramel and flavouring in addition to the distilled mash spirits, and there is no maximum limit on the alcohol level of the distillation.To be exported under one of the "Canadian Whisky" designations, a whisky cannot contain more than 9.09% imported spirits.
