It is the first question many people ask about whisky and the one most often answered wrongly. The spelling — with an e or without — is not a matter of taste or of correctness. It is a matter of geography, with a specific history behind it, a handful of famous exceptions, and a rule that is simpler than the arguments it generates. This piece sets it out.
The short version
Scotland writes whisky. Ireland writes whiskey. Everyone else chose a side.
Canada, Japan, India, Australia, England, Wales, France, Taiwan and most of the rest of the world follow Scotland. The United States mostly follows Ireland, with notable exceptions. If you are writing about a specific bottle, use the spelling on its label. If you are writing about the category in general, use the spelling of the country you are in or the tradition you are discussing. Plural: whiskies and whiskeys, respectively.
That is the whole rule. The rest is history.
The word itself
Both spellings descend from the Gaelic uisce beatha (Irish) or uisge beatha (Scots Gaelic), meaning “water of life” — a translation of the Latin aqua vitae, the medieval term for distilled spirit. English speakers in the sixteenth and seventeenth centuries mangled it into usquebaugh, usky and eventually whisky. For most of the eighteenth century the two spellings were used interchangeably on both sides of the Irish Sea, with whisky more common in print and whiskey a variant. Neither country had settled on one.
Where the e came from
The split dates from the late nineteenth century, and it was commercial.
In the 1870s, Dublin was the centre of the whiskey world. The four great Dublin distillers — John Jameson, William Jameson, John Power and George Roe — made pot still whiskey that was considered the finest in the world and outsold Scotch comfortably. Their threat came from a new kind of Scotch: blends built on cheap grain whisky from the Coffey column still, which Scottish merchants were selling in volume. The Dublin houses regarded this stuff as inferior and, in some cases, as fraudulent; they published a pamphlet in 1878, Truths About Whisky, arguing that column-still spirit should not be allowed to call itself whisky at all.
To distinguish their product from the Scottish blends, the Dublin distillers adopted the spelling with an e and used it consistently. It was branding: “whiskey” meant Irish pot still, “whisky” meant the other thing. Smaller Irish distilleries, particularly in Cork and the north, continued without the e for decades — Bushmills and Paddy used “whisky” into the twentieth century — but the Dublin usage spread and became the national standard. The Irish whiskey style page covers the Dublin era in more detail.
Why America followed Ireland
American distilling in the eighteenth and nineteenth centuries was shaped more by Irish and Scots-Irish immigrants than by Scots, and American usage was mixed well into the twentieth century. The e spelling gradually became the majority convention in the United States, probably because Irish whiskey was the dominant imported style in the mid-nineteenth century and the spelling stuck to the category. By the time bourbon and rye became codified in law, “whiskey” was how most American producers wrote it.
The curious footnote is that the US federal regulations governing spirits use “whisky” — without the e — as the standard spelling throughout, and permit “whiskey” as an alternative. The law follows the older British convention; the industry mostly does not.
The American exceptions
A handful of American brands spell it the Scottish way, and each has a reason.
Maker’s Mark uses “whisky” in tribute to the Samuels family’s Scottish and Scots-Irish ancestry, a decision Bill Samuels Sr made at the brand’s founding in 1953. See the Maker’s Mark page.
George Dickel, the Tennessee distillery, uses “whisky” because its founder, a German immigrant, reportedly considered his product as good as Scotch and wanted the spelling to say so. See the George Dickel page.
Old Forester and Early Times, both Brown-Forman brands, have used “whisky” since the nineteenth century, likely out of the same period convention that the federal regulations preserved.
Jack Daniel’s, Jim Beam, Wild Turkey, Heaven Hill and most of the rest use “whiskey”. The bourbon page notes the spelling on each distillery’s label.
A note on “Scotch”
A related confusion: “Scotch” is not a spelling variant but a legally protected term. Only whisky distilled and matured in Scotland may be called Scotch whisky, and the Scotch Whisky Association pursues misuse of the word around the world with notable energy. In Scotland itself the word is rarely used — Scots say “whisky” and assume you know which — and some drinkers consider “Scotch” an outsider’s term. It is nevertheless the correct and unambiguous name for the category in international usage, and there is nothing wrong with it. “Bourbon”, similarly, is a legal designation for a type of American whiskey, not a brand or a place; it may be made anywhere in the United States, though almost all of it comes from Kentucky. The same logic applies to “Tennessee whiskey”, “Irish whiskey” and, since 2021, “Japanese whisky”: each is a geographic and process designation layered on top of the spelling, and the spelling is the least informative part of the phrase.
For completeness, “malt” and “grain” describe the raw material, “single” describes the number of distilleries, and “blended” describes a mixture; none of them has anything to do with the e either.
The rest of the world
Canada’s industry was built by Scots and used “whisky” from the start. Japan’s was built in deliberate imitation of Scotland by Masataka Taketsuru, who had trained there, and followed suit. India’s enormous domestic industry uses “whisky”. Australia, New Zealand, England and Wales use “whisky”. France, Sweden, Germany, Taiwan and the other newer producing countries almost all use “whisky”, because they model themselves on Scotch.
The e, in other words, is confined to Ireland and most of the United States. Everywhere else, it is a marker of those two traditions.
Style guides and the arguments
Newspapers and publishers have fought over this for decades. British publications generally use “whisky” for everything, including Irish and American products, which irritates the Irish. American publications generally use “whiskey” for everything, including Scotch, which irritates the Scots. The New York Times switched in 2008 from using “whiskey” universally to following the producer’s spelling, after a reader revolt led by Scotch drinkers. Most specialist writers now follow the label.
Caskable’s convention is the same: “whisky” as the general term, because the site covers more Scotch, Japanese and Canadian whisky than Irish and American, and the label spelling for any specific bottle. It is why you will see both forms across the site, including in our reviews, and it is deliberate.
Does it matter?
Only to the extent that it tells you something. A bottle labelled “whisky” is from the Scottish tradition or a country that follows it; “whiskey” is from Ireland or the United States, with the exceptions noted. Neither spelling says anything about quality, grain, process or age. Our label guide covers the words that do, and the whisky glossary has the rest of the vocabulary.
The spelling was, in the end, a Victorian marketing trick that became a tradition, and it has outlived every argument the Dublin distillers made with it. The column-still Scotch they despised now outsells their pot still a hundred to one. The e survived; the case for it did not.
