Two clear spirits, both usually around 40% ABV, both sold in the same aisle, both drunk with tonic. The question of what actually separates gin from vodka comes up constantly, and most answers stop at "gin tastes of juniper" — which is true but explains almost nothing.
The honest version is stranger and more interesting: gin and vodka start out as the same liquid. Everything that makes them different happens in one production step, and understanding that step tells you most of what you need to know about both — including why you can turn vodka into gin at home, and why you cannot go the other way.
The short answer
Vodka is a neutral spirit made deliberately flavourless. Gin is that same neutral spirit, re-flavoured with juniper and other botanicals. Legally, a spirit cannot be called gin unless juniper is the predominant flavour. Vodka has no botanical requirement at all — its defining characteristic is the absence of character.
Everything else — the base ingredient, the still, the ABV, the price — is variable in both categories and tells you far less than people assume.
Where they are identical: the base spirit
Both gin and vodka begin as ethyl alcohol of agricultural origin: a neutral spirit distilled to around 96% ABV from a fermented agricultural base. That base can be wheat, barley, rye, maize, potatoes, sugar beet, grapes or molasses. At 96% ABV, almost nothing of the original raw material survives in any perceptible way — which is precisely the point.
This is the fact that surprises people most: the grain-versus-potato distinction that vodka marketing leans on so heavily is largely irrelevant by the time the spirit is bottled. A well-made wheat vodka and a well-made potato vodka differ far less than two gins made from the same neutral base with different botanical bills.
So if you want to know where the two spirits actually part company, stop looking at the beginning of the process and look at the end.
Where they diverge: the botanical step
From the neutral spirit onwards, the two categories do the opposite of each other.
Vodka is refined downwards. The producer distils repeatedly and often filters — through charcoal, quartz sand, or simply through more distillation — to strip out whatever congeners, oils and raw-material traces remain. The goal is a spirit that is clean, soft in texture and as close to neutral as the process allows. Under EU and UK law, vodka must be distilled or filtered "so as to selectively reduce the organoleptic characteristics of the raw materials used". Neutrality is written into the definition.
Gin is built upwards. The producer takes the same neutral spirit and deliberately puts flavour back in: juniper first and mandatorily, then some combination of coriander seed, angelica root, orris root, citrus peel, cardamom, liquorice, cassia, black pepper and whatever else the distiller's recipe calls for. Our piece on how gin is made walks through what happens in the still.
One category spends its effort removing; the other spends its effort adding. That is the whole difference, and everything below is a consequence of it.
Juniper is the legal dividing line
Under UK and EU rules, gin must be flavoured with juniper berries (Juniperus communis) and juniper must be the predominant flavour. No juniper, no gin — regardless of how many other botanicals are in the bottle. Vodka carries no equivalent requirement.
Minimum strengths are worth getting right, because they are frequently misreported:
- UK and EU: gin minimum 37.5% ABV; vodka minimum 37.5% ABV. The same floor for both.
- United States: both must be bottled at a minimum of 40% ABV (80 proof).
The widely repeated claim that vodka has a lower legal minimum than gin is simply wrong in the UK and the EU. In practice both categories cluster around 40%, with navy strength gins running from 57% upwards.
Neither spirit requires ageing. Both can be bottled the day they are made — which is why a young distillery can launch a gin but not a whisky.
The four ways gin is actually made
"Gin" covers a wider range of production methods than most drinkers realise, and the label tells you which one you have bought. This matters more for quality than the price does.
- Compound gin. Botanicals are steeped in neutral spirit, or flavourings are simply added, with no second distillation. Legal, cheap, and usually the roughest expression of the category. Sometimes called bathtub gin.
- Distilled gin. Neutral spirit is redistilled in the presence of botanicals. Additional flavourings may be added afterwards. This is the broad quality tier where most craft gin sits.
- London Dry. A method, not a place — you can make London Dry in Sicily. All flavour must come from redistillation, nothing may be added afterwards except water and a trace of sweetening, and no colouring is permitted. It is the strictest common designation. We've written it up in full in what London Dry gin actually means.
- Vapour-infused. The alcohol vapour passes through a basket of botanicals rather than boiling with them, producing a lighter, more delicate extraction. Technically a variation of distilled gin.
Vodka has nothing equivalent. There is no vodka classification that tells you about method in the way "London Dry" does — which is one reason vodka branding relies so heavily on filtration counts and origin stories.
Can you turn vodka into gin? Yes. And that says a lot.
Put juniper berries and a few botanicals into a bottle of vodka, wait a day or two, strain it, and you have made compound gin. It is legal to sell in the UK and EU as long as juniper is the predominant flavour and it hits 37.5% ABV. It cannot be labelled distilled gin or London Dry, because no redistillation took place.
The reverse is impossible. You cannot remove juniper from a gin to obtain vodka — the botanicals are chemically integrated into the spirit, and no amount of filtration returns it to neutral.
That asymmetry is the cleanest way to understand the relationship between the two: vodka is the raw material, gin is the finished construction. Historically it ran the same way — gin's ancestor, Dutch genever, was a malt spirit flavoured with juniper for medicinal purposes, as we cover in the history of gin.
How they actually taste
Vodka is judged on texture rather than flavour: mouthfeel, weight, the presence or absence of a burn on the finish, a faint sweetness or minerality from the base. Good vodka is soft and clean. Bad vodka is harsh and solvent-like. The vocabulary is deliberately narrow, because the category is defined by restraint.
Gin is judged the way you would judge a perfume. Juniper gives the piney, resinous, faintly peppery backbone. Coriander brings citrus and spice. Angelica and orris root are structural — they bind the other aromas and give the gin length. Citrus peel lifts the top notes; cardamom, cassia and pepper add warmth. A contemporary or flavoured gin may push fruit or floral notes well forward, but juniper still has to be identifiable.
A practical consequence: a mediocre gin is more obvious than a mediocre vodka. Vodka can hide behind neutrality and cold temperature. Gin has to declare itself in the glass.
In cocktails, they are not interchangeable
Swapping one for the other does not produce a variation on the same drink — it produces a different drink, and usually a less structured one.
- Gin and tonic vs vodka and tonic. Quinine is bitter and needs something aromatic to push against. Gin's botanicals meet it; vodka leaves the bitterness exposed with nothing to balance it.
- Martini. A gin Martini is a conversation between juniper and vermouth. A vodka Martini is about texture and cold. Both are legitimate; they are not the same drink.
- Negroni. Essentially gin-only. Take the gin out and the bitter and vermouth have nothing to stand against.
- Espresso Martini, Moscow Mule, Bloody Mary. Vodka's territory, precisely because a neutral spirit lets a dominant flavour lead.
The rule of thumb: if the drink is built around the spirit, use gin. If the drink is built around something else, vodka gets out of the way. Our guide to the most iconic gin cocktails covers the first category in detail.
Calories, hangovers and other persistent myths
"Vodka is lower in calories." Not meaningfully. At the same ABV and volume, gin and vodka are within a couple of calories of each other — around 95–110 kcal per 50 ml at 40%. Almost all the calories in a spirit come from the alcohol. Any real difference in your glass comes from the mixer, and full-sugar tonic contributes considerably more than the choice of spirit does.
"Gin causes worse hangovers." There's no good evidence for this at equivalent alcohol intake. Darker spirits carry more congeners; both gin and vodka are clear, unaged and low in them.
"More distillations means better vodka." A marketing number. Beyond a certain point additional distillation strips character without adding quality, and the count is unregulated.
"Expensive gin is smoother." Sometimes. But price in gin tracks botanical cost, batch size and brand as much as it tracks quality — a point we unpack in what actually makes a gin premium.
Gin against the other clear and aged spirits
Since we are drawing lines, it's worth placing gin against the rest of the shelf. The distinguishing variable in every case is what happens after fermentation.
- Vodka: neutral spirit, deliberately stripped of character. Same starting point as gin, opposite intention.
- Whisky: distilled from fermented grain to a much lower strength, so the raw material survives, then aged in wood for years. Flavour comes from grain and barrel, never from added botanicals.
- Rum: distilled from sugarcane juice or molasses. Flavour comes from the base and, often, from ageing. No botanical step.
- Tequila and mezcal: distilled from cooked agave. The raw material dominates entirely; mezcal adds smoke from the roasting pits.
- Grappa and other pomace brandies: distilled from grape pomace. Aromatic, but the aroma comes from the fruit, not from added botanicals.
- Genever: gin's Dutch ancestor. A malt-wine base with juniper — halfway between whisky and gin, and legally its own category.
Seen this way, gin is the outlier: it is the only major category whose defining flavour is added on purpose rather than inherited from the raw material or the barrel. For the full taxonomy, see our gin wiki and our piece on what distilled gin means.
Which should you buy?
Choose vodka if you want a spirit that disappears into a drink, if you mix with strong flavours like coffee, tomato or ginger, or if you simply don't enjoy juniper.
Choose gin if you want the spirit to be the point. If you drink gin and tonic, Negroni or Martini; if you enjoy aromatic complexity; or if you want a category where the differences between bottles are large and genuinely worth exploring.
For most people the honest answer is that gin offers more to discover. Two vodkas at the same price are more alike than different. Two gins at the same price can be nearly unrelated drinks.
Frequently asked questions
Is gin stronger than vodka? No. In the UK and EU both have a 37.5% ABV minimum, and both typically bottle at around 40%.
Is gin just flavoured vodka? Close enough to be a useful shorthand, but incomplete. Both start from the same neutral spirit; the distinction is that in distilled gin the botanicals are redistilled with the spirit rather than steeped into it.
Does gin have sugar in it? London Dry is limited to a trace — 0.1 g of sugar per litre. Old Tom and many contemporary gins are sweetened more.
Which is better for a gin and tonic — obviously gin, but why? Because tonic's quinine is bitter, and bitterness needs an aromatic counterweight. Vodka provides none.
Can gin go off? Not in the sense of spoiling, but an opened bottle loses aromatic intensity over months as the volatile compounds fade. Vodka, having far less to lose, is more forgiving.
A gin worth comparing
The clearest way to feel the difference is to taste a gin whose botanicals are unmistakable. GIN NIRO, the artisanal Sicilian gin distilled with Zibibbo grapes — 70 cl — is built on Mediterranean citrus and juniper, and set beside a neutral vodka the contrast is immediate: one spirit steps forward, the other steps back.
