Vermouth is an aromatised wine flavoured with herbs, roots, spices and other botanicals. Wormwood is historically associated with the category and gives vermouth its name. Vermouth is commonly fortified with grape spirit, and styles range from dry to sweet, with white, red and amber examples.
Dry vermouth is generally pale, lighter in sweetness and herbaceous. Sweet vermouth may be red or white and has a more pronounced sweetness and botanical profile. Bianco or blanc styles are typically pale and sweeter than dry vermouth. Formulations differ by producer and region, so the label and tasting profile matter more than colour alone.
Dry vermouth is often used in place of white wine in sauces, seafood preparations and deglazing, although its botanical character will influence the dish. Sweet vermouth is used in cocktails such as the Manhattan and Negroni and can add herbal sweetness to reductions or dessert preparations. Use it in measured quantities and adjust other seasoning and acidity to maintain balance.
Example: use dry vermouth to deglaze a pan for a fish sauce, or a small amount of sweet vermouth in a savoury reduction or classic cocktail.
Because vermouth is wine-based, it can oxidise after opening. Keep it refrigerated, tightly closed and follow the producer’s guidance for use after opening. It is not a neutral one-for-one substitute for dry white wine: its botanicals, sweetness and fortification affect the final flavour.
Chef’s tip: taste the vermouth before using it in a sauce. Adjust the amount of added sugar, salt and acid to suit its style.
