Which wine region in the Loire Valley is known for Muscadet sur Lie?

The region known for Muscadet sur Lie in the Loire Valley is Nantais. Muscadet sur Lie is a designation for wines produced in this area, specifically using the Melon de Bourgogne grape. This style of wine is characterized by its youthful and fresh profile, often enriched by the process of aging on the lees, which adds complexity and texture.

Nantais is situated toward the western part of the Loire Valley and is directly adjacent to the Atlantic Ocean. The proximity to the ocean influences the climate and the style of wine produced, making it an ideal region for the production of Muscadet.

The other regions in the Loire Valley—Touraine, Anjou-Saumur, and the Central Vineyards—are known for various other grape varieties and wine styles, but they do not specifically focus on Muscadet sur Lie. Hence, while these regions contribute to the diversity of the Loire Valley, they are not associated with the notable production of Muscadet sur Lie as Nantais is.
