Domaine Mosse

René Mosse trained and worked as a sommelier and wine merchant before returning to take over his family's small vineyard at Saint-Lambert-du-Lattay in 1999. Together with his wife Agnès he progressively converted the vineyards to organic and then biodynamic farming, earning Demeter certification within the first decade. The estate grew through the 2000s as the Mosse family acquired adjacent parcels and restored abandoned old-vine blocks. Their sons Sylvestre and Joseph have since joined the estate, bringing the natural-wine sensibility into a second generation. The estate has been a primary node in the Loire natural-wine community for over twenty years.

The estate's 16 hectares span schist and clay-over-schist parcels around Saint-Lambert-du-Lattay, on the same Anjou Noir geological complex that defines the broader Coteaux du Layon and Savennières. Plantings include the four principal Loire Chenin Blanc and Cabernet Franc varieties plus the rarer Grolleau (used historically for Anjou rosé) and Pineau d'Aunis (a near-extinct red variety that the Mosses have championed). The schist provides the structural acidity that anchors the Chenin Blanc bottlings, while the clay-over-schist gives the reds a fleshier mid-palate. Old vines aged 50 to 80 years occupy several of the most important parcels.

The estate is fully biodynamic with Demeter certification and follows a minimal-intervention cellar protocol. Fruit is hand-harvested, pressed slowly with no temperature control, fermented with native yeasts in old oak foudres or amphorae, and aged on the lees for periods ranging from 12 to 30 months depending on cuvée. The estate uses very little or no added sulfur, with many bottlings released completely without sulfur. The refusal of conventional cellar additives, combined with the AOC framework's restrictions on natural-wine style, has pushed most Mosse bottlings out of the AOC system and into the Vin de France category, where labeling is more permissive.

• Very little or no added sulfur; many bottlings released completely without sulfur
• Most bottlings labeled Vin de France rather than AOC due to natural-wine stylistic refusal of the AOC framework

The Mosse range covers dry and lightly sweet Chenin Blanc, Cabernet Franc and Grolleau reds, and a rare Pineau d'Aunis bottling. Bangarang and Magic of Ju-Ju are the entry-level whites, made for early drinking. The estate's flagship dry Chenin Blanc is Bonnes Blanches, a single-parcel bottling from old vines on schist. The red range includes Magic, Moussamoussettes (a méthode ancestrale Pet Nat rosé), and the rare Pineau d'Aunis bottling. The estate produces only small quantities of each cuvée and tends to release wines after extended aging, sometimes well after the initial commercial release window typical of AOC Anjou.

Domaine Mosse is one of the four or five reference estates of the modern Loire natural-wine movement, alongside Mark Angeli (Ferme de la Sansonnière), Richard Leroy, Catherine et Pierre Breton, and Olivier Cousin. The Mosse position is particularly important because the estate works across the full Anjou range (Chenin, Cab Franc, Grolleau, Pineau d'Aunis) rather than specializing in a single style or AOC, and because the family's natural-wine commitment has been sustained for more than two decades. The estate's refusal of the AOC framework on stylistic grounds (with most bottlings labeled Vin de France) has been a notable factor in the broader debate about whether natural wine fits within the French appellation system.
