Dubonnet is a French quinine-based aperitif that was created in 1846 by Sir Joseph Dubonnet, a Parisian wine merchant and a chemist. He combined fortified red wine with a secret combination of herbs and spices. His initial desire was to incorporate quinine—which was used to cure malaria—to make it more palatable for French soldiers stationed in North Africa.
The drink soon became a favorite in France, and in the 1940s a slightly different version was created in the United States. Interestingly, Dubonnet is often quoted as a favorite drink of Queen Elizabeth II who prefers to combine it with gin. Although it can be enjoyed on its own, preferably served over ice, Dubonnet is commonly combined with carbonated drinks such as sparkling wine or club soda.
