Whiskey vs Whisky: Does the Spelling Matter?
"Whisky" is the Scottish spelling, while America adopted the term "whiskey". Both refer to the same category of distilled grain spirits, just with different regional conventions.
With Scottish products, "blended Scotch whisky" is the correct terminology. However, American publications often use "whiskey", so you'll encounter both spellings used interchangeably in different contexts.
