Which AC in southern France is known for premium full-bodied red wines based on the Mourvedre grape?

The region recognized for premium full-bodied red wines primarily made from the Mourvèdre grape is Bandol AOC. Bandol is situated along the Mediterranean coast in southern France and is particularly noted for its robust and complex red wines. Mourvèdre thrives in the region's climate, contributing to wines that exhibit depth, ageability, and characteristic flavors such as dark fruit, spice, and earthy notes.

The unique terroir of Bandol, with its clay and limestone soils, along with a climate that features hot summers and cool, windy influences, creates ideal conditions for Mourvèdre to flourish, allowing it to develop rich tannins and concentrated flavors. This distinguishes Bandol AOC as a benchmark for wines made from this varietal, especially when compared to other neighboring regions.

In contrast, while other mentioned appellations include Mourvèdre in their blends (such as Minervois, Côtes de Provence, and Fitou), they typically do not focus on it to the same premium extent as Bandol, often producing lighter or less complex examples. Hence, Bandol's reputation for high-quality, full-bodied red wines based on Mourvèdre solidifies its position as the correct answer.
