Difference between Whisky and Whiskey

 The main difference between whisky and whiskey is the country of origin and the spelling.

Whisky without the "e" is the term generally used for the spirit produced in Scotland, Canada, and Japan, as well as in some other countries that follow their methods of production.

Whiskey with the "e" is the term generally used for the spirit produced in Ireland and the United States, as well as some other countries that follow their methods of production.

There are also some differences in production methods and flavor profiles between different types of whiskies and whiskeys, but the spelling is the easiest way to distinguish between the two.
