Vermouth is a wine: a fortified, aromatized wine, flavored with herbs, roots, barks and spices, strengthened with added alcohol to around 16 to 18 percent, and usually sweetened. It comes in two classic styles, dry vermouth, pale and French in origin, and sweet vermouth, red and Italian, plus a pale, sweeter style called blanc. Because it is a wine and not a spirit, it does go bad once it is open: it slowly oxidizes, so an opened bottle belongs in the fridge and is best finished within one to three months.
Below: what goes into a bottle, how American and European rules define it, how dry, sweet and blanc differ, what vermouth tastes like, how long it keeps, and what to use when you have none.
| Also called | Looks and tastes | Sugar | |
|---|---|---|---|
| Dry vermouth | French vermouth; extra-dry is the driest | Pale, light, herbal, more bitter than sweet | Generally 4% or less |
| Sweet vermouth | Italian vermouth, rosso, red | Red, fuller, bittersweet and spiced | Usually 10 to 15% |
| Blanc vermouth | Bianco | Pale like dry, but much sweeter | Well above dry |
What is vermouth made of?
Vermouth starts as wine, usually a light, neutral white wine. The producer adds extra alcohol, most often a neutral grape spirit, steeps a blend of dry botanicals in it, and sweetens it with cane sugar or caramelized sugar, depending on the style. Red vermouth takes its color from the botanicals, from added red wine or from caramel. Every house keeps its recipe secret, but cloves, cinnamon, quinine, citrus peel, cardamom, chamomile, coriander, juniper and ginger are all common, as Wikipedia's entry on vermouth lists them. Several of those are gin botanicals too, which is one reason the two get along so well; the ten in our own gin are set out in behind the bottle: the ten botanicals.
The name comes from one herb in particular. "Vermouth" is the French pronunciation of the German Wermut, wormwood, a bitter herb that has flavored these wines throughout their history. European law still requires it: vermouth's characteristic taste must come from Artemisia, the wormwood genus. In the United States, the Food and Drug Administration lists wormwood as a natural flavoring that may be used only if the finished product is thujone free (21 CFR 172.510), thujone being a compound in the plant's essential oil.
Is vermouth alcoholic? A wine, not a liquor
Yes, and in law it is a wine on both sides of the Atlantic. In the United States, vermouth sits in the federal standards of identity for wine, not for spirits. 27 CFR 4.21 lists it as a type of aperitif wine, which must be at least 15 percent alcohol by volume, compounded from grape wine with added brandy or alcohol, and flavored with herbs and other natural aromatic flavoring materials. Vermouth is the type with "the taste, aroma, and characteristics generally attributed to vermouth." The American rule names no particular herb.
In the European Union, vermouth is an aromatized wine under Regulation (EU) No 251/2014. Grape wine must make up at least 75 percent of the volume, and the finished drink must be at least 14.5 and less than 22 percent alcohol by volume.
In the bottle, most vermouths land at 16 to 18 percent, against 9 to 14 percent for most unfortified wines, by Wikipedia's figures. That is less than half the strength of gin, which starts at 40 percent, as we explain in how strong is gin. The National Institute on Alcohol Abuse and Alcoholism counts 3 to 4 fluid ounces of fortified wine as one US standard drink.
Dry vs sweet vermouth: what is the difference?
The two classic styles were born a few decades apart. Sweet vermouth came first: a merchant in Turin introduced it in 1786. The first pale, dry vermouth followed in France between about 1800 and 1813, according to Wikipedia's history of the drink. That is why the red style is still called Italian vermouth and the pale one French.
Dry vermouth is pale, light-bodied and more bitter than sweet, with sugar generally at 4 percent or less. Its extra bitterness often comes from nutmeg or bitter orange peel. Sweet vermouth is red, fuller and bittersweet, usually with 10 to 15 percent sugar. In Europe the sweetness words on a label are defined by law: "extra-dry" means less than 30 grams of sugar per liter, "dry" less than 50 grams, and "sweet" 130 grams or more, under Article 6 of the same EU regulation. Swap one style for the other in a recipe and the drink changes completely, so the bottle the recipe names is the one to use.
What is blanc vermouth?
Blanc, or bianco, is a third style: pale like dry vermouth but much sweeter, as the Wine & Spirit Education Trust describes it. The style began in Chambéry, in Savoie, a French town with a protected name for its vermouths. Producers also make extra-dry, amber and rosé versions.
What does vermouth taste like?
Like a light wine that has been through the spice cabinet. Underneath sits the wine; on top come bitterness from wormwood or quinine, warmth from clove and cinnamon, brightness from citrus peel, and enough sugar to pull it together. Dry vermouth tastes crisp, herbal and faintly bitter, close to a dry white wine with a long, bitter finish. Sweet vermouth tastes rounder, spiced and bittersweet. Blanc is softer still, with the sweetness in front and the herbs behind.
Served cold, on its own or over ice with a twist of lemon, vermouth is an aperitif, and in Italy, France and Spain that is often how it is drunk. In the United States it has long been best known as a cocktail ingredient, where it plays the part that bitterness plays in tonic: it gives the gin something to push against, as we describe in what gin tastes like.
What is vermouth used for?
Vermouth's best-known job is the martini, gin stirred over ice with dry vermouth. Sweet vermouth makes the Negroni, an Italian aperitif of equal parts gin, sweet vermouth and Campari, as Wikipedia's entry on the Negroni describes it, and the Manhattan, made with whiskey. Our house versions of the first two, the Classic Gatsby Martini and the West Egg, are in the Gatsby cocktail library. Away from the bar, dry vermouth goes into the kitchen as an alternative to white wine, in sauces for fish and in marinades for pork and chicken.
Gatsby Gin is a London Dry gin of ten botanicals, made in small batches in a copper pot still in Fort Myers, Florida. Its juniper, coriander and cardamom are spices found in many vermouths, and its bitter orange peel meets the orange garnish of a Negroni. It was shortlisted for America's Best Negroni in ADI's 2026 Perfect Pour awards, as we report in our 2026 ADI results.
Does vermouth go bad?
Yes, slowly, once it is open. The added alcohol gives an opened bottle a far longer life than a table wine, but vermouth is still wine, and once air reaches it, it starts to oxidize. The herbal aromas fade and the wine goes dull. Gin behaves differently: at 40 percent alcohol or more it does not spoil, and an opened bottle fades over many months, as we explain in does gin go bad. Vermouth, a wine at less than half that strength, needs looking after.
How long does vermouth last?
Unopened, a bottle can sit at room temperature with no loss of quality, according to VinePair's vermouth guide. Once opened, keep it in the fridge, ideally sealed with a vacuum stopper, as the Wine & Spirit Education Trust advises, and finish it within one to three months, the window given in Wikipedia's entry on vermouth. Cold slows the oxidation; it does not stop it. A smaller bottle you will finish beats a large one that sits.
How to tell if vermouth has gone off
Pour a little and smell it. Fresh vermouth smells of herbs, citrus and wine. A tired one smells flat or faintly sour, like a white wine left open too long, and the herbs have gone quiet. It will make a dull drink, so it is time for a new bottle.
What can you use instead of vermouth?
In the kitchen, dry vermouth and dry white wine do the same job, so a dry white wine can stand in for dry vermouth in a sauce or a marinade, with less herbal flavor. In a drink, nothing replaces it exactly. The nearest options are another style of vermouth, with blanc in place of dry giving a softer, sweeter drink, or another aromatized wine, such as a quinquina, which European rules define as a bitter aromatized wine flavored mainly with natural quinine.
