Vin doux naturel is a type of fortified sweet wine from France, known for its rich flavors and natural sweetness. It is made by adding grape spirit to the fermentation process, which stops the fermentation and preserves the natural sugars in the grapes. This results in a wine that is both sweet and has a higher alcohol content. Typically produced in regions like Roussillon and Languedoc, vin doux naturel can be made from various grape varieties, including Muscat and Grenache. These wines are often enjoyed as dessert wines or paired with cheeses and fruit, showcasing their unique balance of sweetness and complexity.
