Sweet vermouth is a red, aromatized, fortified wine that’s slightly sweet and packed with herbs and spices; it’s a classic cocktail ingredient and a popular aperitif on its own.

What it is

Sweet vermouth is made by taking a base wine (often white or pale red), fortifying it with a neutral spirit (like brandy) to raise the alcohol, then infusing it with a secret blend of botanicals — usually including wormwood (the “vermouth” plant), plus herbs, roots, barks, and citrus peels. It’s then sweetened, giving it a richer, rounder, and more approachable profile than dry vermouth.

Modern sweet vermouth is typically red or amber in color and has flavors of caramel, vanilla, baking spices (cinnamon, clove), dried fruit, and bitter herbs, with a smooth, slightly syrupy mouthfeel.

Origins and history

The first commercial sweet vermouth was created in 1786 in Turin, Italy, by wine merchant Antonio Benedetto Carpano. He used Moscato wine, added alcohol and a mix of local herbs and spices, and called it “Wermut” (from the German word for wormwood).

Carpano’s sweet, aromatic wine quickly became a favorite of the Savoy royal court and helped turn vermouth into a fashionable aperitif across Europe. Over time, Italian-style sweet vermouth (rosso/rosso dolce) became the standard for cocktails like the Manhattan and Negroni.

How it’s used

Sweet vermouth is a key player in many classic cocktails:

  • Manhattan – Whiskey (usually rye or bourbon), sweet vermouth, and bitters.
  • Negroni – Equal parts gin, sweet vermouth, and Campari.
  • Americano – Sweet vermouth, Campari, and soda water.
  • Old Pal / Boulevardier – Variations that swap or add whiskey to the Negroni template.

It’s also commonly served chilled on its own, over ice, sometimes with a citrus twist or a splash of soda, especially in Italy and Spain as an aperitif.

Popular brands

Some well‑known sweet vermouth brands include:

  • Carpano Antica Formula – Rich, full‑bodied, with notes of vanilla, cocoa, and spice.
  • Martini & Rossi Rosso – A widely available, balanced sweet vermouth, great for cocktails.
  • Cocchi Vermouth di Torino – A modern take on the classic Turin style, with dried fruit and spice.
  • Punt e Mes – A slightly bitter, more complex sweet vermouth from Carpano, often used in Negroni variations.

How to store and serve

Once opened, sweet vermouth should be kept in the refrigerator and consumed within 1–3 months, as it can oxidize and lose its freshness. It’s best served chilled, either:

  • Neat, over ice, with an orange twist.
  • In cocktails, stirred or shaken depending on the drink.

TL;DR
Sweet vermouth is a red, herbal, slightly sweet fortified wine invented in Turin in 1786; it’s essential in cocktails like the Manhattan and Negroni, and also great chilled as an aperitif.
