Old Tom Gin
A lightly sweetened gin, rounder than London Dry and older than it. The Victorian classics were written for this style, which is why some of them read drier today than their authors can have intended.

Tasting Notes
Juniper leads as ever, but cushioned: a light sweetness rounds the botanicals where London Dry angles them. Fuller texture, gentler landing.

Storage & Handling
As any gin: sealed, upright, out of light.
Usage
Poured as gin is, at 50ml, in anything predating about 1900. The Martinez and the Tom Collins were built on its sweetness, so a build using it wants less syrup than the same recipe made with a London Dry.
The Cat on the Wall
The name is usually traced to a piece of eighteenth-century tax evasion. After the Gin Act of 1736 made retail gin prohibitively expensive to license, the story goes that a shopkeeper mounted a wooden cat on the wall outside, and a customer would put a coin in a slot under its paw and receive a measure of gin through a tube beneath. Whether the detail is exact or embroidered, the sign of the old tom cat became attached to the sweetened gin sold that way, and the name outlived both the tax and the trick.
The Missing Link
Old Tom sits between genever and London Dry in a straight line of descent. Genever is malt-wine based, heavy and closer to a whiskey in body. London Dry is neutral-spirit based, bone dry and juniper-forward. Old Tom is the intermediate stage: lighter than genever, sweeter than London Dry, and for most of the nineteenth century it was simply what gin meant. Reading a Victorian recipe with modern London Dry in hand is therefore substituting an ingredient that had not been invented when the drink was written.
Modern Old Tom Is Not One Thing
The style nearly died and came back through revival distillers rather than continuous production, which means there is no settled house standard. Some modern bottles are barely sweetened and read as a soft London Dry. Others carry noticeable sugar. A few are rested in barrel, which adds colour and weight that no historical Old Tom necessarily had. That variability matters in a recipe, because a spec written around one bottle can be unbalanced by another, so tasting before pouring is worth more here than in most categories.
The Drinks It Was Written For
The Martinez is the clearest case, and it is the drink most often blamed on the wrong ingredient: made with London Dry it is sharp and slightly hollow, and made with Old Tom the maraschino and vermouth suddenly have something to sit against. The Tom Collins is named for the gin rather than the other way round. The Ramos Gin Fizz and a good deal of the pre-Prohibition canon assume it too, and all of them soften noticeably when it is used.
Pro Tip
When a Victorian recipe just says "gin", it usually means this. Old Tom first, then adjust, not the other way round.
Top Tips
- Swap it into a Martinez before judging that drink. It was written for this gin, not for London Dry.
- Reduce the added sugar when you substitute it. The sweetness is already in the bottle.
- Taste before assuming. Modern Old Toms range from barely sweetened to frankly sweet.
Possible Substitutions
- London Dry plus a small nudge of syrup (approximation, not equivalence)
- Genever for something older still
History & Context
Old Tom is the missing link between Dutch genever and London Dry: sweetened in its era partly to soften rough distillate, and named, the story goes, for the black tomcat plaques on pub walls that dispensed it through a slot to discreet drinkers. It faded as column stills made dry gin clean enough to need no sugar, then returned when the craft revival went looking for the gin the old recipe books meant.
Common Questions
What is Old Tom gin?
A lightly sweetened style of gin, rounder and softer than London Dry, that was the dominant form through most of the nineteenth century. It sits between genever and London Dry in the family, and the Victorian classics were written assuming it rather than the dry style.
Old Tom versus London Dry?
Old Tom carries some sugar and reads softer and rounder; London Dry is bone dry and juniper-forward. Swapping London Dry into a recipe written for Old Tom leaves the drink sharper and thinner than intended, which is why the Martinez has a reputation for being austere.
Where does the name come from?
Most likely from a wooden cat mounted outside eighteenth-century premises selling gin without a licence, where a coin in a slot brought a measure through a tube. The sign of the old tom cat attached itself to the sweetened gin and outlasted both the tax and the dodge.
What drinks call for Old Tom?
The Martinez above all, where it changes the drink completely, and the Tom Collins, which is named for the gin. The Ramos Gin Fizz and much of the pre-Prohibition canon assume it too. Broadly, anything gin-based written before about 1900.
