What’s the Difference Between Whiskey and Whisky?
Published Date: November 1, 2025
If you’ve ever stood in front of a bar shelf and wondered why some bottles are labeled “whiskey” while others proudly display “whisky,” you’re not alone. This tiny letter “e” has sparked debates among spirit enthusiasts, historians, and bartenders for decades.
While the two spellings might look interchangeable, they actually point to geographic origin, production style, and cultural tradition. Whether you’re sipping a smooth Kentucky bourbon or a smoky Scotch from Islay, knowing the difference between whiskey and whisky can deepen your appreciation for every pour.
Let’s break down the nuances, from how they’re made to where they come from — and why that one little vowel matters.
Where the Spelling Comes From
The easiest way to remember it is simple:
-
“Whiskey” — with an e — is used in Ireland and the United States.
-
“Whisky” — without an e — is used in Scotland, Canada, and Japan.
This spelling distinction dates back to the late 19th century when Irish distillers wanted to differentiate their smoother, triple-distilled spirits from the heavier Scotch whiskies flooding the market. Over time, American distillers adopted the Irish spelling as a nod to the many Irish immigrants who helped shape U.S. whiskey culture.

How Whiskey and Whisky Are Made
Though both come from fermented grain mash, the production techniques vary depending on the region — and that’s what gives each spirit its unique character.
1. Ingredients and Grain Choices
-
Irish Whiskey is typically made from malted and unmalted barley, resulting in a lighter, smoother profile.
-
Scotch Whisky is often made from 100% malted barley and aged in oak barrels for at least three years.
-
American Whiskey, including bourbon, must contain at least 51% corn, giving it a sweeter and fuller flavor.

2. Distillation Process
Irish and American whiskeys often go through triple distillation, which refines and softens the spirit. Scotch whiskies are usually double distilled, preserving more robust, smoky flavors — especially in peated varieties from regions like Islay.
3. Aging & Maturation
Both whiskey and whisky gain their depth and color from time spent in oak casks. However, U.S. law requires bourbon to age in new, charred oak barrels, while Scotch and Irish whiskies can use refilled casks (often previously used for sherry or wine), adding layers of complexity.

Flavor Profiles: Sweet vs. Smoky
If you’re comparing a bourbon to a Scotch, you’ll immediately notice their opposing personalities:
-
Bourbon (U.S.) – Rich, sweet, and full-bodied with notes of vanilla, caramel, and spice.
-
Irish Whiskey – Smooth, light, and approachable, often with hints of honey and fruit.
-
Scotch Whisky – Smoky, earthy, and complex, with flavor influenced by the region and peat levels.
