Open the EU spirit drinks regulation looking for Old Tom Gin and you won't find it. That isn't an oversight: European law recognises three gin categories — gin, distilled gin and London gin — and Old Tom is none of them. Yet it has been one of the most-used words on cocktail menus for fifteen years, and without it half the drinks of the 1800s simply don't come out right.
It's a historical style, not a protected denomination. And like every historical style, it is defined by how it tastes rather than by what the label is allowed to say.
What Old Tom gin is
Old Tom is a lightly sweetened gin: a juniper spirit with sugar added — discreetly today, far more generously in its day. It sits exactly between two worlds: drier than the Dutch genever gin descends from, rounder and softer than the London Dry that came after it.
Born in the 18th century, for well over a hundred years it simply was gin — what London drank before modern column stills made it possible to produce a spirit clean enough to stand on its own.
Why it was sweetened (the reason isn't indulgence)
The sugar had nothing to do with a sweet tooth: it was there to cover. Eighteenth-century stills turned out a rough spirit, often flawed and not infrequently "improved" with things you would not want in a glass, from liquorice to turpentine. Sweetening it was the fastest way to make it drinkable.
Once distillation improved, the crutch became unnecessary. Drinkers discovered that a clean gin needs no sweetening, London Dry took over, and Old Tom slipped out of fashion — rare by the 1940s, all but gone by the 1970s.
Where the name comes from
Here the stories pile up. The most repeated one involves the puss and mew shops: illicit gin outlets marked by a black cat, where you posted a coin through a slot and a measure of gin came back down a pipe. A lovely tale, and probably a later invention — the man usually credited with the scheme never once mentions "Old Tom" in his own account.
The likelier version is duller: Thomas Chamberlain, a distiller, and his apprentice Thomas Norris. When Norris opened his own gin palace in Covent Garden, the gin he sold carried an "Old Tom" label — almost certainly a nod to his master. A man's name that turned into a category.
What it tastes like
You know a good Old Tom on the first sip because the mouthfeel is softer and fuller than a London Dry without ever being sugary. The juniper is there but rounded off; spice and root notes come forward; the finish is short and warm rather than dry and sharp.
Sweetness in modern Old Toms is modest — a touch, not a syrup. Anyone expecting a liqueur is in for a surprise. If you want to train your palate to read these differences, our guide to tasting gin covers the method.
The revival, and why it happened
Hayman's brought Old Tom back to market in 2007, reviving a family recipe. The timing was no accident: these were the years bartenders were digging through 19th-century recipe books and finding that those drinks, made with a London Dry, didn't work. They had been written for a sweeter gin.
The category reopened from there, and today producers in England, Scotland, Sweden and beyond bottle their own.
How to drink it
- In pre-Prohibition classics: this is its home ground. The Martinez — ancestor of the Dry Martini — falls into balance with an Old Tom and stays angular with a dry gin.
- In a Tom Collins: the drink was born with Old Tom. Use it and you should cut back the sugar syrup.
- In a G&T: it works, but it changes the register. You need a dry, low-sugar tonic and a sharp citrus to balance it, or the drink turns cloying. The basics still apply — see our perfect gin and tonic guide.
- Neat: rarely. This is a mixing gin, not a sipping gin.
FAQ
What's the difference between Old Tom and London Dry?
London Dry may not be sweetened beyond a token 0.1 g of sugars per litre and may only use natural flavourings added during distillation. Old Tom is sweetened afterwards, noticeably: softer in the mouth, less sharp on the finish.
Is Old Tom gin as sweet as a liqueur?
No. Modern Old Toms carry a restrained sweetness, nowhere near a juniper liqueur such as sloe gin. It is still a gin, with juniper up front.
Is there a legal definition of Old Tom?
No — not in Europe, and nowhere as a protected category. It is a style name: each producer decides how much sugar goes in, which is why two Old Toms from different distilleries can be a long way apart.
Can I substitute London Dry plus syrup?
As a stopgap it works, and in a cocktail it gets close. What you can't replicate is the texture: in an Old Tom the sweetness is built in, not laid on top.
And GIN NIRO? Ours sits on the other side of that line: a dry gin, with a citrus backbone and a Zibibbo grape note that gives it roundness without any added sugar. If the idea of a soft but dry gin appeals, try it here. To find your way around the other styles, there's our gin wiki.
