What Is Vermouth? It’s Wine, and Yours Is Probably Dead

Vermouth is wine that has been fortified and flavoured. It sits in a legal family the EU calls “aromatised wine products”, and vermouth is the specific member of that family defined by wormwood. Under Regulation (EU) No 251/2014, a product can only be sold as vermouth if wine makes up at least 75% of it, alcohol has been added, the finished drink sits between 14.5% and 22% ABV, and its character comes from appropriate species of Artemisia, the wormwood genus. No wormwood, no vermouth. That is not marketing. That is law.

Worth separating the regulated facts from the romance early, because producers blur the two constantly. The wine base, the wormwood and the ABV band are legally fixed. The evocative talk of “secret blends of 40 botanicals sourced from the finest corners of the earth” is brand storytelling, and while it may well be true, it is not what makes something a vermouth. The wine and the wormwood are. Everything else is seasoning, literally and commercially.

Four things go into vermouth: a base wine, a fortifying spirit, botanicals, and sweetener. The base is usually a fairly neutral, unremarkable white wine, chosen precisely because it does not shout, so the botanicals have room to speak. The fortifying spirit, normally a clean grape spirit, pushes the strength up to the typical 16 to 18% and helps preserve the drink. The sweetening comes from sugar, caramelised sugar or grape must, and the colour of red vermouth comes largely from caramel, not from the grapes.

Then there is the wormwood, and it earns its starring role. Wormwood is a bitter plant of the Artemisia genus, and the very name vermouth comes from the German word for it, wermut. It brings the characteristic dry, herbal bitterness that separates vermouth from every other flavoured wine, and historically it carried a medicinal reputation too, wormwood having long been used as a digestive and, less charmingly, to clear intestinal worms. Around it sit the supporting botanicals: warm spices, roots like gentian and angelica, citrus peel, flowers and herbs, added by steeping, or as concentrated tinctures and distillates. Blend those with the wine and spirit and you have vermouth.

Here is the fact that catches almost everyone out. Sweet red vermouth is, more often than not, made from white wine. When Antonio Benedetto Carpano created the first modern vermouth in Turin in 1786, he used white Moscato, and the red colour of classic Italian rosso comes from added caramel, not from red grapes. This is why colour is a hopeless guide to what is in the glass. A deep amber-red rosso and a water-clear bianco can both be made from the same pale wine, and can carry almost identical amounts of sugar. The colour tells you about caramel. It tells you nothing reliable about sweetness or grape. File that away, because half of vermouth’s reputation for being confusing comes from people assuming red means red-wine and red means sweet. Neither is dependable.

Vermouth comes in a handful of styles. The sugar levels behind the labels “extra dry”, “dry”, and so on are set by EU sugar bands, so those terms are regulated; broader style names like “bianco” are more convention than strict law. Here is the honest map, including what each one actually tastes like.

Notice the trap the table exposes: bianco is pale and sweet, dry is pale and dry. Same colour, opposite sugar. If you buy on the label’s shade you will get this wrong every time.

The production sequence is short and, crucially, not identical between producers, which is why no two vermouths taste the same. The broad steps are always these.

People have steeped wine with bitter herbs since antiquity, and the Greeks, Romans and others made medicinal wormwood wines. It is tempting, and wrong, to call those early tonics “vermouth”. They are ancestors, not the same drink. Modern commercial vermouth has a clear birthday: 1786, in Turin, when the herbalist Antonio Benedetto Carpano fortified and sweetened good Moscato wine, flavoured it with wormwood and other botanicals, and sold it from his shop near the royal palace. It became a sensation, reputedly popular enough that the shop stayed open around the clock, and it turned Turin into the capital of vermouth.

France took the idea and went the other way. In 1813 the herbalist Joseph Noilly made a pale, bone-dry, deliberately weathered style at Marseillan that became Noilly Prat, and in 1821 Joseph Chavasse launched a lighter alpine style at Chambery, the house that became Dolin and the only French vermouth ever to hold an appellation d’origine. So the two great traditions split early: rich and sweet in Italian Turin, dry and herbal in French Marseillan and Chambery. Spain then built its own culture around the drink entirely, the beloved “hora del vermut”, vermouth hour, where it is poured cold from the tap at lunchtime with olives and anchovies. The single most protected name is Vermouth di Torino, guarded as a geographical denomination since 1991 and formalised as a protected geographical indication, made in Piedmont from Italian wine with Piedmontese wormwood. When you see that on a label it means something legally. “Turin-style” on anything else usually just means marketing.

The great secret, which the Spanish and Italians never forgot and the British spent a century ignoring, is that vermouth is a drink in its own right, not just a cocktail ingredient. Pour a good one cold over ice, add a twist of orange or lemon and maybe an olive, and you have a low-strength aperitivo that puts most pre-dinner drinks to shame. Top it with soda for something longer and lighter. Drop bianco or rosato into a spritz with prosecco and soda for the easiest crowd-pleaser going. Or drink it neat and slightly chilled, the way a Turin regular would, and let the botanicals unfold. None of this requires gin, or a shaker, or a single ounce of ceremony. It just requires the bottle to be fresh, which brings us, shortly, to the bad news.

Get the style right and half the cocktail is already made. Get it wrong, dry where it wanted sweet, and no amount of good gin will save you.

Dry vermouth is one of the most useful bottles in a kitchen, and here is the genuinely handy part: because it is fortified, it survives being open far longer than a bottle of cooking white, so it is the more practical choice for the odd splash. Use it anywhere a recipe asks for dry white wine. It deglazes a pan beautifully, lifts a risotto, sharpens a cream sauce for chicken or fish, and steams mussels superbly. Sweet vermouth earns its place too, in braises and rich meat sauces where you want a little spiced depth. It behaves like the fortified wines we cover in our guide to the wines worth actually cooking with, and the same rule applies: cook with something you would happily drink, never a “cooking” version full of salt.

A few beliefs need putting down gently. “Vermouth is a spirit.” No, it is fortified wine, which is exactly why it perishes. “It lasts forever once opened.” It lasts weeks, not years. “Red means sweet, white means dry.” Colour comes from caramel and tells you almost nothing about sugar, as bianco proves by being pale and sweet at once. “Red vermouth is made from red wine.” Usually it is white wine plus caramel. “All vermouth is made the same way.” Producers differ at every step, which is the whole point of trying more than one. And “the ancient Greeks drank vermouth.” They drank herbal medicinal wine, an ancestor, but modern vermouth starts with Carpano in 1786. Believe the ingredients on the shelf, not the folklore.

After decades as the ingredient nobody thought about, vermouth is genuinely fashionable again, and the reasons are easy to read. Drinkers want lower-alcohol options, and a vermouth over ice at around 16% is a far gentler evening than a spirit. Spritz culture has made aperitivo drinking mainstream, and vermouth sits at the heart of it. And a wave of premium regional producers, from Piedmont to Catalonia to a growing British scene, has given people bottles worth drinking on their own rather than hiding in a Martini. The category has quietly shifted from supporting act to headliner.

The marketing has followed the money. In 2025 the Bacardi-owned brand MARTINI signed the actor Jonathan Bailey as its “Martini Man”, following the likes of George Clooney, in a campaign leaning hard on spritzes and Italian aperitivo style rather than the old dry-Martini formality. It is a small, telling sign of where the category thinks its future is: sunlit, sociable and sipped long, not stirred stiff.
