Scotch whisky

Whisky vs Whiskey: The spelling Whisky is used for whiskies distilled in Scotland, Wales, Canada, and Japan, while Whiskey is only used for the spirits distilled in Ireland and America. However, a 1968 directive of the United States Bureau of Alcohol, Tobacco and Firearms now specifies Whisky as the official U.S. spelling!
Scotch whisky is whisky made in Scotland. In Britain, the term whisky is usually taken to mean Scotch unless otherwise specified. In other English-speaking countries, it is often referred to as "Scotch".
