Sweet Vermouth
Sweet Vermouth
Also known as: Rosso vermouth, Red vermouth, Italian vermouth
Rich, warming, and botanically complex — the vermouth behind the Manhattan, the Negroni, and some of the most enduring cocktails ever made.
What is Sweet Vermouth?
Sweet vermouth is a fortified, aromatised wine — white wine strengthened with neutral spirit and infused with a proprietary blend of botanicals — with caramel or other colouring agents added to give it its characteristic deep ruby red colour. Unlike dry vermouth, which has very little residual sugar, sweet vermouth is genuinely sweet, with a rich, warming character built on herbs, bitter bark, dried fruit, and spice. It’s the oldest and most complex of the three vermouth styles, and the one with the widest cocktail repertoire. For a full overview of all three styles, see our vermouth guide.
The style originated in Turin in the late 18th century — the first commercial sweet vermouth is generally credited to Antonio Benedetto Carpano, who began producing it in 1786. The Italian tradition of sweet vermouth remains the dominant one today, with brands like Martini Rosso and Cinzano being the most widely recognised, and Carpano Antica Formula representing the premium end of the category. It’s occasionally called “Italian vermouth” to distinguish it from “French vermouth” — the dry style — though both countries now produce both styles.
In cocktails, sweet vermouth is doing two things simultaneously: adding sweetness to balance bitter or strong spirits, and contributing genuine botanical complexity. A well-made sweet vermouth — particularly at the premium end — has enough character to meaningfully improve a Manhattan or Negroni, not just sweeten it. That’s why the brand you choose matters more than people often realise.
Flavour Profile
Sweet vermouth leads with rich, warming sweetness — dark fruit, vanilla, and caramel — with a herbal and bitter undercurrent that keeps it from being cloying. The botanicals vary significantly by brand: some lean towards bitter bark and medicinal herbs, others towards dried fruit and spice. The wine base gives it genuine depth that distinguishes it from simpler sweet liqueurs, and a good bottle has a long, complex finish. It’s the kind of ingredient that rewards spending a little more — cheap sweet vermouth tastes thin and overly sweet; a quality bottle adds genuine layers to a cocktail.
The Three Vermouth Styles
Sweet vermouth is the richest and most complex of the three styles — but the others are equally useful behind the bar and shouldn’t be treated as interchangeable.
Dry Vermouth
Also: French vermouth, Extra Dry
Bone dry, crisp, herbal, and floral. Very little sugar. The Martini vermouth — pairs best with gin and vodka.

Also: Rosso, Red vermouth, Italian vermouth
Rich, warming, sweet with dark fruit and botanical complexity. The Manhattan and Negroni vermouth.

Also: Blanc, White vermouth
Sweet white vermouth with vanilla, citrus, and floral notes. Softer and more approachable than sweet or dry styles.

Sweet vermouth is a category where spending a little more makes a noticeable difference — particularly in spirit-forward stirred cocktails where it’s sharing equal billing with the base spirit. These are the brands worth knowing.
Carpano Antica Formula
The premium sweet vermouth that most serious bartenders reach for first. Made in Turin to a recipe that traces back to Carpano’s original 1786 formula, it’s rich, complex, and vanilla-forward with notes of dried fruit, bitter herbs, and warm spice. It will noticeably improve any stirred cocktail that calls for sweet vermouth — particularly a Manhattan or Boulevardier.

A historic Turinese vermouth with a more pronounced bitterness than Carpano — closer to a classic amaro in character, with citrus peel, cocoa, and gentian driving the flavour alongside the sweetness. An excellent choice for Negroni variations where you want the vermouth to add edge as well as body.
~£18–22 / 75cl
Buy on Master of MaltDolin Rouge
A lighter, more delicate sweet vermouth from Chambéry — the home of French vermouth. Less rich and complex than the Italian styles but beautifully balanced, with a fresh red fruit quality and moderate sweetness. Works particularly well in cocktails where you want the sweet vermouth to play a supporting rather than leading role.
~£13–17 / 75cl
Buy on Master of MaltMartini Rosso
The most widely available sweet vermouth in the UK, and a perfectly serviceable everyday option. It’s lighter and less complex than Carpano or Cocchi, with a clean, straightforwardly sweet character. Solid in casual cocktails and punches — though for a serious Manhattan or Negroni, it’s worth stepping up to one of the premium options.

Substitutes for Sweet Vermouth
Sweet vermouth’s combination of wine base, sweetness, and botanical complexity is hard to fully replicate, but these options will get you close depending on what you’re making.
Amaro (Averna, Montenegro, Ramazzotti)
The closest in character — bitter Italian liqueurs with similar botanical profiles. Higher in alcohol and more bitter than sweet vermouth, so use about two-thirds of the quantity and expect a drier, more complex result. Works particularly well in Negroni and Manhattan variations.
Port (Ruby or Tawny)
A fortified wine with similar sweetness and body. Ruby port works well in Manhattan-style drinks — use the same quantity as the vermouth called for. You’ll lose the botanical complexity but keep the wine richness and sweetness.
Punt e Mes
An Italian vermouth with a noticeably more bitter character than standard sweet vermouth — halfway between a sweet vermouth and an amaro. Use 1:1 and expect a more assertive, bitter result. Excellent in Negroni variations.
Bianco Vermouth (adjusted)
If you only have bianco vermouth, it’ll work in a pinch — the sweetness level is similar, but the character is lighter and more floral. Add a small dash of Angostura bitters to approximate the herbal depth of the sweet style.
Cocktails That Use Sweet Vermouth
Sweet vermouth appears in some of the most enduring stirred cocktails ever made — drinks where its richness and botanical depth are doing essential structural work alongside the base spirit.
Storage — This One Really Matters
The most common sweet vermouth mistake
Sweet vermouth is wine. It oxidises after opening and will taste flat, vinegary, or off within weeks at room temperature. The higher sugar content means it lasts a little longer than dry vermouth once open — but not much. Refrigerate after opening and replace regularly, especially if you use it infrequently.
Temperature
Refrigerate immediately after opening. Room temperature storage accelerates oxidation significantly — even the higher sugar content won’t protect it for long.
Sealing
Reseal tightly after every use. Air is the enemy — even a loosely capped bottle will degrade noticeably faster than one properly sealed.
Once open
Best within 4–6 weeks in the fridge. The higher sugar content gives it a slight edge over dry vermouth, but quality still drops off noticeably after the first month.
Unopened
Store in a cool, dark place away from direct sunlight. Shelf life is typically 3–5 years unopened — check the best before date on the bottle.
As with dry vermouth, if you make Manhattans or Negronis infrequently, a smaller bottle is almost always a better idea than a standard 75cl that sits in the fridge for months. A fresh half-bottle will produce a noticeably better drink than a stale full one.
