The Real McCoy, Hooch and Whisky: Which Word Origins Are True?
“The real McCoy” has a Scottish paper trail beginning with “the real Mackay” in 1848, long before the rum runner usually linked to it. “Hooch” leads back to a Tlingit people in Alaska, while “whisky” comes through Scots and Irish from uisge beatha, “water of life”. Those histories have different degrees of certainty: the Scottish National Dictionary still calls the ultimate origin of “the real Mackay” obscure.[1][2][9][11][12]
The real McCoy: the phrase came before the famous names
The Scottish National Dictionary defines “the real Mackay” as “the genuine article, the true original, the real home product”. It also records its use for a brand of whisky, but the expression was not confined to drink.[1]
The earliest dated printed example found by Wordorigins is in the Arbroath Guide of 12 February 1848. Its story concerns a con man exchanging a man's hat for an imitation. Nobody in the story is named Mackay, and the phrase appears without explanation, suggesting that readers already recognised it.[2]
An early printed example establishes that an expression existed by a particular date; it does not necessarily reveal who invented it. The unexplained wording in the hat story suggests that readers already knew it.[2]
One proposed origin is Disputed. The Scottish National Dictionary suggests that “real” may be a corruption of Reay, the Sutherland title of the Mackay chiefs. Wordorigins removed the theory because it considered the evidence insufficient.[1][2]
The next examples show the saying moving between subjects. A June 1856 newspaper story identifies a true heir as the “real M'Kay”; an 1861 beekeeping letter uses “the ‘real Mackay's’”. By 1884, a Tit-Bits question and answer collection explains “It's no the real Mackay” simply as “it is not genuine”.[4]

The poem places the phrase in a drinking context with “A drappie o' the real M'Kay”, without requiring any later McCoy story. Its cover gives only 1856, however, so it cannot be placed before or after the June newspaper example within that year.[1][4]
The spelling “real McCoy” appears in James S. Bond's Canadian book The Rise and Fall of the “Union Club” in 1881: “It's the ‘real McCoy,’ as Jim Hicks says.” This is evidence for that spelling, not evidence that the whole expression began in Canada.[2][3]
Three McCoy origin stories, three legends
The inventor, the boxer and the rum runner offer memorable explanations. The difficulty is chronological: the Scottish expression was already in print before the events supposed to have created it.[2][5][7]
Elijah McCoy and the railway lubricator
Elijah McCoy patented an “Improvement in Lubricators for Steam-Engines” in 1872. The National Park Service repeats the account that railroaders asked for his equipment by name, but supplies no dated citation for that wording.[6]
Claim: Requests for Elijah McCoy's lubricator originated “the real McCoy”.
Verdict: Legend
What the record shows: His 1872 patent is documented; “the real Mackay” was printed in Scotland in 1848.[2][6]
Evidence against or gap: A dated railway example is not supplied, and the earlier expression remains unexplained by this story.
Earliest known source: The earliest telling is not established in the supplied research; the account checked is the National Park Service article, undated.

Kid McCoy and the boxing story
The Los Angeles Times examined the claim that boxer Kid McCoy supplied the expression and labelled it “STATUS: False”. Its decisive point is that the phrase was already printed while he was a child, with the Scottish form earlier still.[5]
Claim: Boxer Kid McCoy originated “the real McCoy”.
Verdict: Legend
What the record shows: The McCoy spelling is recorded in 1881; the Mackay form is recorded in 1848.[2]
Evidence against or gap: The chronology rules out the boxer as the origin of the earlier expression.[5]
Earliest known source: The earliest telling is not established; the critical account checked was published on 4 October 2012.

Bill McCoy and Prohibition liquor
Bill McCoy has a genuine place in the whisky story. On 1 August 1921, the Coast Guard cutter Seneca seized his schooner Henry L. Marshall carrying 1,250 cases of Scotch whisky. Naval History describes this as the Coast Guard's first major alcohol seizure of Prohibition.[8]
Claim: Bill McCoy's undiluted liquor originated “the real McCoy”.
Verdict: Legend
What the record shows: His Prohibition activities came decades after both recorded forms of the expression.[2][8]
Evidence against or gap: Monmouth Timeline calls an origin with him “highly unlikely”.[7]
Earliest known source: The earliest telling is not established in the supplied research.

There is nevertheless a later connection worth preserving. Etymonline says the phrase became popular for liquor during Prohibition, and Monmouth Timeline records McCoy selling whisky as “The Real McCoy” in 1933. Association and commercial use are supported; invention is not.[3][7]
Hooch: Alaska before the Klondike
“Hooch” takes us away from Scottish surnames. Wordorigins traces it to the name of the Xutsnoowú, a Tlingit people traditionally living around Angoon, Alaska. Etymonline reports the Oxford English Dictionary's derivation from Tlingit Hutsnuwu, literally “grizzly bear fort”.[9][10]
The longer drink name appears as “hoochenoo” in a dispatch datelined 23 December 1874, published by San Francisco's Daily Evening Bulletin on 13 January 1875. That distinction between the dispatch date and publication date explains why both years appear in its history.[9]
On 20 March 1875, the Weekly Alta California described “their home-brew, yclept ‘Hoochinoo’”, reporting demand after liquor imports were banned. These newspaper examples put the longer form well before the supposed Klondike origin.[9]
The shortened “hooch” is recorded in M. H. E. Hayne and W. West Taylor's The Pioneers of the Klondyke, published in 1897. Describing the winter of 1895 to 1896, it says: “This concoction was known as ‘hooch’”. Hayne explains that whisky supplies were very limited.[9][10]
The dates need reading carefully. The book supplies a printed example in 1897 describing an earlier winter; it does not establish the exact moment when someone first shortened the word. Likewise, Etymonline's 1877 date for “Hoochinoo” is overtaken by the earlier newspaper evidence assembled by Wordorigins.[9][10]
Two familiar shortcuts therefore fail. “Hooch” was not coined during the 1898 Klondike gold rush, and the drink word has no connection with “hooch” meaning a hut.[9]
Whisky: a shortened Gaelic inheritance
The Scottish National Dictionary traces “usquebae” to Gaelic and Irish uisge beatha, meaning “water of life”, or aquavitae. It records the Old Scots form iskie bae in 1583, giving the word family a written history well before the familiar short form.[11]
Martin Martin's Description of the Western Islands, published in 1703, mentions islanders who “brew several sorts of liquor, as common Usquebaugh”. The quotation documents that older name in use; it should not be read as a modern production definition.[11]
The dictionary's earliest dated quotation for “whisky” is from 1715: “Whiskie shall put our brains in rage”. Its recorded forms include whiskie, whiskey, whusky, huskie in 1745 and the shortened whisk in Lanarkshire around 1779.[12]
According to the dictionary, the word passed from Scots and Irish into Standard English in the middle of the eighteenth century. “Whisky” was therefore not always an English word, nor does its early written history consist of one fixed spelling.[12] For other terms used around whisky, see whisky slang explained.
A short chronology of the evidence
| Date | Recorded evidence | What it establishes |
|---|---|---|
| 1583 | Old Scots iskie bae | An early form in the whisky word family.[11] |
| 1715 | “Whiskie” | The dictionary's earliest dated whisky quotation.[12] |
| 1848 | “The real Mackay” | The expression predates the famous McCoy explanations.[2] |
| 1875 | Printed “hoochenoo” dispatch | The longer drink name predates the Klondike account.[9] |
| 1881 | “The real McCoy” | A recorded example of the McCoy spelling.[2][3] |
| 1897 | Printed “hooch” | The shortened form describes the winter of 1895 to 1896.[9] |
