How long will Dubonnet last?
Simply so, does Dubonnet go bad?
Because Dubonnet has a relatively low alcoholic content (19 percent, or 38 proof), I always store it in the refrigerator after I open a bottle (to retard oxidization). If you don't refrigerate opened Dubonnet, it won't necessarily go “bad,” but after a month or two its flavor won't be as bright.
Moreover, what does Dubonnet taste like?
The fortified wine contains herbs, spices and quinine, the malaria-fighting but very bitter ingredient that gives Dubonnet a bit of an edge. Served straight, Dubonnet has a viscous mouth feel and a spicy, fruity taste; something like Campari meets sweet vermouth.
Dubonnet Blanc is similar to dry vermouth and is the drier of the two. It is made with a white wine base. Either variety of Dubonnet can be served on its own when well-chilled or as a spritzer when topped with sparkling water or club soda. You can also use them in any cocktail that calls for vermouth.
