Whiskey is a broad category of spirits, while Scotch is a type of whiskey. Think of it like squares and rectangles - all Scotch is whiskey, but not all whiskey is Scotch!
The key difference lies in origin and production. Scotch must be made in Scotland, primarily from malted barley, and aged in oak barrels for at least three years. It often boasts smoky or peaty notes due to the way the barley is dried.
Other whiskeys, like Bourbon (USA) and Irish Whiskey (Ireland), have their own specific rules regarding ingredients and production. Bourbon, for instance, is made primarily from corn. These distinct regulations and ingredients create vastly different flavor profiles. So, next time you're faced with a whiskey selection, remember: Scotch is a specific type of whiskey with unique Scottish origins and character.
