Is it whiskey or whisky? That single letter ‘e’ has sparked plenty of confusion, conversation, and (dare I say) anger in the whisk(e)y community. But this is more than a spelling issue. It’s a story of history, geography, flavor, and national identity.
Where the Word Comes From
Both “whiskey” and “whisky” come from the same source. The word traces back to the Scottish Gaelic phrase uisge beatha, which means “water of life.” That phrase, in turn, comes from the Latin aqua vitae, used during the Middle Ages to describe distilled alcohol.
Over time, uisge beatha evolved phonetically into “usky” and then into “whisky.” The spelling difference came later, as the spirit traveled the globe.
Whisky vs. Whiskey: Which Is Right?
The spelling depends on where the spirit is made. Here’s the general rule:
Must Read Stories
Whiskey with an e is used in Ireland and the United States
Whisky without an e is used in Scotland, Canada, Japan, India, Australia, New Zealand, etc. Basically, any whisky-producing nation that isn’t Ireland or the United States.
This is not a hard rule, though. For example, Maker’s Mark is a Kentucky bourbon brand, but it uses the Scottish spelling, “whisky.” Additionally, Beyonce’s SirDavis brand calls its spirit “whisky”. In fact, according to official TTB legislation, the legal spelling is still “whisky”. However, most U.S. producers use the spelling with an ‘e’.
The Whisky Professor, writing for scotchwhisky.com in 2017, said: “In fact, the Bureau of Alcohol, Tobacco and Firearms (BATF) regulations… use the spelling ‘whisky’ as the correct legal term. ‘Whiskey’ is permitted because it is traditional. The majority of distillers, you could argue, are exceptions and those such as Maker’s and Dickel are abiding by the law.”
There are similar anomalies in historical texts, where Irish distillers sometimes used the spelling without an ‘e’, and Scottish distillers used it with one.
The plural form follows the same pattern. We say whiskeys for American or Irish styles, and whiskies for scotch and most others. Again, though, there are some exceptions.
So, where did the ‘e’ come from? The common theory is that 19th-century Irish distillers added it to distinguish their whiskey from lower-quality scotch at the time. When Irish immigrants brought their distilling skills to the United States, they brought the spelling with them.
Regional Rules and Styles
The spelling is just one part of the story. Other differences lie in the production process, legal definitions, and flavor.
Scotch Whisky
Scotch is governed by strict rules. To be labeled “scotch whisky,” the spirit must be:
- Distilled and aged in Scotland
- Matured in oak barrels for at least three years
- Made from water, malted barley, and other whole grains
The Scotch Whisky Association defines five official types:
- Single Malt Scotch: 100% malted barley, from one distillery
- Single Grain Scotch: Can include other grains, also from one distillery
- Blended Malt Scotch: A mix of single malts from multiple distilleries
- Blended Grain Scotch: A mix of single grain whiskies
- Blended Scotch: A mix of malt and grain whiskies
American Whiskey
American whiskey is more diverse. The Alcohol and Tobacco Tax and Trade Bureau (TTB) regulates the category, and there are several subtypes:
- Bourbon: At least 51% corn, aged in new charred oak barrels
- Tennessee Whiskey: Bourbon made in Tennessee with charcoal filtering
- Rye Whiskey: At least 51% rye grain
- Corn Whiskey, Wheat Whiskey, Malt Whiskey
- Blended Whiskey, Straight Whiskey, Light Whiskey
- American Single Malt: 100% malted barley, aged in new, charred, or used oak barrels and made at a single distillery
(Note that the above definitions are simplified. If I were to write about the specific and lengthy requirements for each style, this article would be very long. With that being said, let me know if that is something you would like to see on The Whiskey Wash.)
Each whiskey style has its own mash bill, distillation method, and aging requirements. These rules shape the spirit just as much as regional traditions do.
What About Canada, Japan, and Beyond?
Canadian whisky is usually spelled without the ‘e’. It often includes a high proportion of rye grain, which gives it a lighter, spicier profile.
Japanese whisky tends to follow Scottish methods. Many distilleries use copper pot stills and import barley from Scotland. The spelling reflects this alignment.
Other countries like Australia, France, and India tend to use the “whisky” spelling too, often emulating either the Scottish or Japanese style.
Can You Taste the Difference?
In many cases, yes. But not because of the spelling.
In very simple terms, scotch tends to have an earthier quality than whiskies from other regions, especially when peated. Single malts offer rich, complex layers. Irish whiskey is typically triple-distilled, which gives it a lighter, smoother taste.
American whiskey has a sweeter profile, especially in bourbon, due to its high corn content. Rye whiskeys are often bolder and spicier.
That said, there’s no single flavor that separates all “whiskeys” from all “whiskies.” The ingredients, distillation process, and barrels used all play a role.
The best way to know what you’re drinking is to read the label. Check where it was made and how. That will tell you far more than how the word is spelled.
Lew Bryson, author of Tasting Whiskey: An Insider’s Guide to the Unique Pleasures of the World’s Finest Spirits, pointed to the difference in atmosphere when drinking different types of whiskies as well:
“Good friends and good whiskey are a great thing, and they’re all a bit different. When I think of nights drinking bourbon, I think of laughter and card playing. When I think of nights drinking Scotch, I think of music and, more often than not, talking about whisky. But when I think of the nights I’ve enjoyed Irish whiskey, what I think of are stories.”
So, whilst the spelling difference might be arbitrary, it can also speak to diverging experiences when enjoying one type of whisky vs. another. It has nothing to do with the spelling and everything to do with style.
So, Which One Is Correct?
Both.
“Whiskey” and “whisky” are equally valid. They reflect local spelling preferences and production traditions. The important part is not how it’s spelled, but how it’s made and what it tastes like.
In the end, it’s all about personal taste. The only real mistake is not enjoying what’s in your glass.
And if you’re about to point out my spelling, don’t worry. I’m fluent in both whisky and whiskey.
