Noilly PRAT is a French brand of vermouth, an aromatized fortified wine. It was created in 1813 by Joseph Noilly and his son Louis-Claude Noilly. The brand is now owned by the Italian company Martini & Rossi. Noilly PRAT is known for its dry style, which is made from white wines from the south of France. The vermouth is aged in oak barrels for up to two years, and is flavored with herbs and spices. It is often used as an aperitif or as a base for cocktails.
