Domaine du Penlois produces wines from Beaujolais, the storied French region known for its elegant, fruit-driven expressions. The winery works primarily with Gamay and Chardonnay, the region's foundational varieties. Its flagship Sous l'aile du Moulin Moulin-à-Vent, a Gamay-based wine, has been assessed by Wine Enthusiast, Wine Spectator, and Wine Advocate. The domaine also crafts a Beaujolais Blanc from Chardonnay, alongside the Chardonnay du Chatelard Beaujolais. These wines reflect the character of their terroir: Gamay's bright acidity and red-fruit profile, and Chardonnay's mineral precision and structure. The winery's portfolio spans the range of what Beaujolais offers—from the lighter, more delicate expressions to wines with deeper complexity and aging potential.
