Final answer:
Banyuls and Maury in the south of France are well-known for their production of Vins Doux Naturels from red grapes, benefiting from the ideal Mediterranean climate conducive to growing Grenache, among other grape varieties.
Step-by-step explanation:
Two areas in the south of France that are renowned for producing Vins Doux Naturels (VDN) from red grapes are Banyuls and Maury. These areas benefit from the Mediterranean climate, characterized by hot, dry summers and mild winters. This climate is ideal for growing a variety of fruits, including wine grapes, as the weather conditions allow for a long and slow ripening period, which is essential for the development of flavors and sugars in the grapes used in VDN production.
Vins Doux Naturels are a type of sweet wine made from overripe grapes. The fermentation process is stopped early by the addition of alcohol, retaining some of the natural sweetness of the grape juice. Banyuls and Maury both produce VDN from red grapes like Grenache, which thrive in their warm and sunny climate.
Moreover, the terroir, or the combination of soil, topography, and climate, of these regions contribute to the distinctive taste profiles of their sweet wines. The tradition and expertise of VDN production in these areas are reflected in the high quality of the wines they produce, which are enjoyed by connoisseurs around the world.
