Vin Doux Naturel (VDN) from Southern France is a sweet fortified wine made by adding grape spirit during fermentation, which stops fermentation and preserves natural grape sugar.
These wines often show rich flavors of dried fruit, cocoa, caramel, and spice, depending on the grape and aging style.
The most famous examples come from Roussillon appellations like Banyuls and Maury, often made from Grenache and sometimes aged oxidatively for a nutty, complex style.
Think of Vin Doux Naturel as France’s answer to Port—sweet, powerful, and best enjoyed in small glasses, often with dessert or cheese.
