SCEA Vignobles Bonnange

A Blaye estate using limestone-and-clay parcels for Bordeaux blends, single-variety reds and grape-specific bottlings.

The producer

Château Bonnange, the estate name of SCEA Vignobles Bonnange, works in Saint-Martin-Lacaussade in Bordeaux’s Blaye area. Limestone-and-clay parcels, vines averaging about 30 years old and some plots over a century old supply wines made across Bordeaux and Blaye-Côtes-de-Bordeaux. Paul-Emmanuel Boulmé leads technical direction, with natural yeasts, small-lot fermentation and varied ageing vessels keeping grapes and parcels distinct.

The range moves from blended reds to Petit Merle, Le Cab and Cot, then wines matching individual grapes to selected soils. Le Clos de Bonnange gives the clearest blended shape: 80% Merlot, 15% Cabernet Sauvignon and 5% Malbec, aged 18 months in oak. Merlot brings body, Cabernet Sauvignon brings tannin and a drier line, while oak adds spice and broadens the texture through the finish.

Blaye reds that compare Bordeaux blending, single varieties and limestone-and-clay parcels.

Notable facts

The story

From Clos des Roberts to Château Bonnange

In 1999, Claude Bonnange acquired the vineyard known as Clos des Roberts and renamed it Château Bonnange. Bonnange had founded TBWA, but he chose Blaye’s limestone-and-clay ground for his wine project and brought in Paul-Emmanuel Boulmé of Château Terre-Blanche for the winemaking. By 2003, Boulmé had joined the estate’s winemaking partnership. He later took technical direction and has made the wines for the past 20 years. The renamed estate still stands at 10 chemin des Roberts in Saint-Martin-Lacaussade, preserving the earlier vineyard name in its address.

At A Glance

Château Bonnange is the estate name used by SCEA Vignobles Bonnange at 10 chemin des Roberts in Saint-Martin-Lacaussade, in Bordeaux’s Blaye area. Its work moves between Bordeaux and Blaye-Côtes-de-Bordeaux, with blended reds, single-variety wines and bottlings that match grapes to limestone-and-clay parcels. The result is a range built for comparison rather than one fixed house formula.

The Producer

Michael is the owner and inspirer at Château Bonnange, while Franck leads general management and sales and Paul-Emmanuel Boulmé directs the technical side. Boulmé has made the wines for two decades, so the estate’s current bottles join a long cellar hand to a vineyard programme that separates grapes and parcels instead of folding every crop into one blend.

Place

Saint-Martin-Lacaussade sits in the Blaye area of Bordeaux, and Château Bonnange works with both Bordeaux and Blaye-Côtes-de-Bordeaux wines. That dual address matters on the label: Bordeaux blending provides the familiar Merlot-and-Cabernet framework, while the Blaye parcels supply the limestone-and-clay ground used for the estate’s more grape-specific bottlings.

Soil And Site

The vineyard is divided among limestone-and-clay terroirs rather than treated as a single block. Its vines average about 30 years old, and some plots are more than a century old; those older plantings bring established root systems into the fruit supply, which makes parcel-by-parcel handling in the cellar a practical choice rather than decoration.

Story

Claude Bonnange, founder of TBWA, acquired the vineyard in 1999 after choosing Blaye’s terroirs for a wine project. He brought Paul-Emmanuel Boulmé of Château Terre-Blanche into the winemaking, and the estate now carries that decision forward through natural-yeast fermentations, small lots and several ageing vessels. The range therefore does not stop at a conventional Bordeaux blend: it also isolates Merlot, Cabernet and Cot, then places individual grapes on selected soils.

Vineyards And Cellar

Organic conversion is under way in the vines, where limestone-and-clay parcels and old plots are worked as distinct sources of fruit. In the cellar, natural yeasts and small-lot fermentation keep those sources separate before ageing. That sequence allows a Merlot parcel, a Cabernet parcel or a blended lot to retain its own fruit, tannin and weight before oak or another vessel shapes the finish.

Wines

The Château Bonnange wines present the estate’s blended Bordeaux side, while Le Clos de Bonnange provides a named red with a documented structure of 80% Merlot, 15% Cabernet Sauvignon and 5% Malbec. Its 18 months in oak put fruit, tannin and oak on the same frame: Merlot supplies the broad central body, Cabernet Sauvignon contributes firmer grip, and Malbec adds another dark-fruit register.

Petit Merle, Le Cab and Cot move from blending toward single-variety expression. Alongside them are three wines that pair individual grapes with specific limestone-and-clay soils. The range can therefore be approached by structure: blend for layered body and tannin, varietal bottlings for a more direct grape profile, then soil-matched wines for how ground changes fruit and texture.

In The Glass

Le Clos de Bonnange is the fullest documented guide to the estate’s red style. Merlot’s body carries the centre of the palate, Cabernet Sauvignon brings tannin and a drier line through the finish, and the Malbec portion reinforces dark fruit. Eighteen months in oak adds spice and a broader texture, so the wine’s fruit does not arrive as a simple juicy red; it is held by oak, tannin and a sustained finish.

Across the wider range, the useful comparison is not between labels alone. Petit Merle, Le Cab and Cot put one grape in the foreground, while the soil-linked wines shift attention toward the limestone-and-clay parcel beneath it. That makes acidity, body, fruit and grip part of a sequence of contrasts rather than a single house taste repeated bottle after bottle.

A Bottle To Understand It

Start with Le Clos de Bonnange, using the documented 2016 bottling as the reference: 80% Merlot, 15% Cabernet Sauvignon and 5% Malbec, aged for 18 months in oak. It brings the estate’s Bordeaux blend into one glass, with Merlot body, Cabernet tannin, Malbec dark fruit and oak spice gathered into a dry red with weight and a firm finish. The single-variety wines become easier to place after tasting this blended foundation.

Anecdote

In 1999, Claude Bonnange acquired the vineyard then known as Clos des Roberts and renamed it Château Bonnange. Bonnange had founded TBWA, but the project he set in motion was rooted in the Blaye vineyards rather than an advertising office. He entrusted the winemaking to Paul-Emmanuel Boulmé of Château Terre-Blanche, whose work joined the estate by 2003. Boulmé went on to direct its technical work and has made the wines for the past 20 years. The old name remains in the estate’s address: Château Bonnange is still at 10 chemin des Roberts in Saint-Martin-Lacaussade.

Final Word

Château Bonnange is worth seeking out for the way it turns one Blaye property into several useful red-wine comparisons: old and younger vines, limestone-and-clay parcels, blends, varietals and oak-aged structure. Begin with Le Clos de Bonnange, then use Petit Merle, Le Cab and Cot to follow the grapes in a more direct form.
