We call any wine containing more than 45 grams of residual sugar per liter a sweet wine. This doesn't mean that sugar has been added to the wine, but rather that some of the sugars naturally present in the grapes were not fermented.

Sweet wine is a type of wine characterized by having a high residual sugar content and a sweet taste.

They are usually very aromatic wines with a smooth palate, ideal for pairing with desserts or enjoying as an aperitif. Sweet wines are produced in various wine regions around the world and can be red, white, or rosé.

Some examples of famous sweet wines are Port, Sweet Sherry, Tokaji, Sauternes, and Muscat.
