Frédéric Mabileau

Frédéric Mabileau founded his Saint-Nicolas-de-Bourgueil estate in 1991, building it from a modest land base into one of the appellation's most acclaimed estates across three decades. Frédéric had grown up in the Bourgueil-SNDB area and trained in oenology before establishing the operation in his name. For a period he was joined by his brother Laurent in a shared operation; the brothers later resumed independent work, and Frédéric has continued the estate under his own name. His sons have progressively taken on responsibility for vineyard and cellar work during the 2010s and 2020s, and the next-generation transition is well underway. The estate's expansion into Bourgueil and the parallel Anjou project across the Loire have given Frédéric one of the most geographically diverse Cabernet Franc footprints among Loire producers.

• Founded 1991 in Saint-Nicolas-de-Bourgueil by Frédéric Mabileau; built across three decades into an acclaimed estate
• Trained in oenology before establishing the operation; joined for a period by brother Laurent before independent operations resumed
• Sons have progressively taken on responsibility during the 2010s and 2020s; next-generation transition well underway
• Expansion into Bourgueil and parallel Anjou project across the Loire gave Frédéric a geographically diverse Cabernet Franc footprint

The estate covers approximately twenty-seven hectares spread across three appellations on both banks of the Loire. The Saint-Nicolas-de-Bourgueil holdings sit on the sandy gravel alluvial terraces that define the appellation's lighter style, with named parcels Les Rouillères (volume cuvée from younger vines) and Les Coutures (older-vine site with deeper structure). The Bourgueil holdings sit on the tuffeau hillsides north of the appellation, producing the more structured, age-worthy style, with the flagship Eclipse cuvée drawn from a south-facing hillside parcel. The Anjou project sits on the left bank of the Loire and produces Chenin Blanc whites and a small Cabernet Franc line on the schist soils typical of the appellation. The geographic spread gives the estate access to all three of the Loire's major Cabernet Franc terroirs (sandy gravel, tuffeau, schist).

• Approximately twenty-seven hectares across Saint-Nicolas-de-Bourgueil AOC, Bourgueil AOC, and Anjou (left bank of the Loire)
• SNDB: sandy gravel alluvial terraces; named parcels Les Rouillères (volume), Les Coutures (older-vine)
• Bourgueil: tuffeau hillsides north of the appellation; flagship Eclipse cuvée from south-facing hillside parcel
• Anjou: left bank Chenin Blanc whites and small Cabernet Franc line on schist soils

The estate is Demeter biodynamic certified after a long preceding organic discipline that was already in place across the 2000s. The vineyard work uses biodynamic preparations applied on a calendar tied to the lunar cycle, cover crops between the rows, and minimal soil disturbance across the working year. Manual harvest is standard across the named parcels, with sorting at the cellar before vinification. In the cellar, fermentations are conducted with indigenous yeasts in concrete vats and used Burgundy barrels depending on the cuvée. The Cabernet Franc is destemmed on the sandy SNDB cuvées (preserving fruit-forward freshness) and partially whole-cluster on the tuffeau Bourgueil cuvées (adding structure and aromatic complexity). Élevage runs twelve to twenty-four months depending on the cuvée, with the flagship Eclipse receiving the longest aging in used barrels.

• Demeter biodynamic certified after long preceding organic discipline across the 2000s
• Biodynamic preparations, cover crops, and minimal soil disturbance across the working year
• SNDB Cabernet Franc destemmed (fruit-forward); Bourgueil tuffeau cuvées partially whole-cluster (structure and complexity)
• Indigenous yeast fermentations in concrete vats and used Burgundy barrels; 12 to 24 month élevage depending on cuvée

The SNDB range includes Les Rouillères (entry-level volume cuvée from sandy parcels) and Les Coutures (older-vine site with more structure). The Bourgueil range is anchored by the flagship Eclipse, a south-facing tuffeau hillside cuvée given extended élevage and built for fifteen-plus years of cellaring. The Anjou whites include Chenin Blanc bottlings from schist soils on the left bank of the Loire, with the Coutures Anjou Blanc being the most widely distributed of the white line. A small experimental natural-wine line under the broader Mabileau label adds a low-intervention dimension to the range, with cuvées using indigenous yeast and minimal sulfur additions. The combined production across the three appellations gives the estate one of the most diverse output portfolios in the Loire Cabernet Franc world.

• SNDB: Les Rouillères (entry-level sandy-parcel volume cuvée), Les Coutures (older-vine site, more structure)
• Bourgueil: flagship Eclipse, south-facing tuffeau hillside cuvée with extended élevage and 15-plus year cellaring
• Anjou: Chenin Blanc bottlings from schist soils (Coutures Anjou Blanc is the most widely distributed)
• Small experimental natural-wine line with indigenous yeast and minimal sulfur additions adds low-intervention dimension

Frédéric Mabileau sits among the central Saint-Nicolas-de-Bourgueil estates of the modern era, alongside Domaine Yannick Amirault and Domaine Joël Taluau, with the additional dimension of the Bourgueil and Anjou holdings that few SNDB-anchored estates achieve. The Demeter biodynamic certification aligns the estate with the broader Loire biodynamic shift of the 2000s and 2010s, and the parcellary cuvée structure (Les Rouillères, Les Coutures, Eclipse) gives critical writing on the estate a coherent didactic frame. The cross-appellation footprint (SNDB, Bourgueil, Anjou) and the spread across both banks of the Loire give Mabileau one of the most geographically diverse Cabernet Franc operations among Loire producers. Widely distributed in specialist circuits in North America, Northern Europe, and Japan, the estate is a frequent inclusion on serious by-the-glass programs and natural-wine retail in major metropolitan markets.
