Domaine FL (Fournier Longchamps) is a family-owned winery based in Rochefort-sur-Loire in the Anjou region of the Loire Valley, France. The estate was established in the mid-2000s when Philippe Fournier Longchamps consolidated several historic vineyard parcels into a single domain focused on high-quality, terroir-driven wines.

The vineyards extend across both banks of the Loire River, planted on diverse soils rich in schist, limestone, and volcanic elements, which contribute to the wines’ pronounced minerality. Production is centered primarily on Chenin Blanc, a variety that in this region delivers wines with strong structure, vibrant acidity, and excellent aging potential, alongside smaller quantities of Cabernet Franc for red wines.

The style is precise and expressive, with typical notes of citrus, white flowers, honey, and mineral undertones. The estate is certified organic and follows biodynamic principles, emphasizing manual harvesting and minimal intervention in the cellar.

Winemaking often avoids malolactic fermentation to preserve freshness and tension, while oak is used with restraint to maintain clarity of fruit and terroir. Domaine FL is recognized for its work in appellations such as Savennières, Coteaux du Layon, and Quarts de Chaume, producing wines that combine depth, balance, and long-term evolution potential.
