Dubonnet is a sweet, aromatized wine-based quinquina that is often enjoyed as an aperitif. It is a blend of fortified wine, herbs, and spices, with fermentation being stopped by the addition of alcohol. Dubonnet was first sold in 1846 by Joseph Dubonnet, in response to a competition run by the French Government to find a way of persuading French Foreign Legionnaires in North Africa to drink quinine. Quinine combats malaria but is very bitter. Dubonnet is made from four main ingredients: red wine base, herbs and spices, cinchona bark, and cane sugar. It is available in Rouge, Blanc, and Gold (vanilla and orange) varieties. Dubonnet is commonly mixed with lemonade or bitter lemon and forms part of many cocktails.

The Queen of Englands favorite cocktail is a Dubonnet and Gin, which is made by mixing two parts Dubonnet and one part gin, stirred and strained, with an addition of one lemon wedge and two ice cubes or one large ice cube. Dubonnet is a sweet fortified wine aperitif made with herbs and spices. It has a fruity, spicy flavor and hails from France. Dubonnet is a key ingredient in many other cocktails as well, and it is sometimes paired simply with lemonade or bitter.
