Filliatreau produces wines from Saumur, in the Middle Loire Valley, where Cabernet Franc and Chenin Blanc thrive on schist and clay soils. The winery's Vieilles Vignes Saumur-Champigny, made from old-vine Cabernet Franc, expresses the region's signature red character—structured, mineral-driven, with dark fruit and herbaceous notes. The Lena Filliatreau Saumur-Champigny offers a complementary expression of the same varietal, while Château Fouquet Saumur Blanc showcases the region's white tradition through Chenin Blanc, a grape known for its acidity, stone-fruit profile, and aging potential. All three wines have been assessed by major critics including Wine Enthusiast, Wine Advocate, Wine Spectator, and Decanter. Saumur-Champigny, the appellation's flagship red designation, demands Cabernet Franc aged in the region's historic tuffeau caves—conditions that shape the wines' distinctive mineral spine and freshness.
