Château Le Sèpe: Bordeaux Supérieur & Entre-Deux-Mers - Sainte-Radegonde, Gironde

Excellence and organic certification at the heart of the Bordeaux wine country.

History and origins of the estate

After completing their training in viticulture and oenology, Catherine and Dominique Guffond took over Château Le Sèpe in 2009. Two qualified winemakers with a clear direction from the outset: quality cuvées, built on authentic Bordeaux terroir, in the immediate vicinity of the prestigious Saint-Émilion appellation.

The results came quickly: their very first vintage earned a gold medal at the Concours des Vins de Bordeaux, an immediate endorsement that confirmed their vision and laid the foundations for a fast-rising reputation.

The terroir and its unique character

Château Le Sèpe is based in Sainte-Radegonde, a Gironde commune tucked at the gates of Saint-Émilion. This position in the Bordeaux wine country gives the estate a dual identity: the geographical proximity of the Right Bank's greatest terroirs, and the freedom of the Bordeaux Supérieur and Entre-Deux-Mers appellations, allowing the production of both characterful reds and fresh, aromatic whites.

The vineyard covers 14 hectares farmed organically. The two appellations, Bordeaux Supérieur for the reds, Entre-Deux-Mers for the whites, reflect the richness of the terroir and Catherine and Dominique Guffond's desire to explore the full aromatic range that Bordeaux can offer.

Working the vines and our commitments

The organic transition at Château Le Sèpe did not happen overnight. It was built progressively from 2017, a lengthy, exacting conversion that requires rethinking every action in the vineyard before anything changes in the winery. Catherine and Dominique Guffond approached it methodically, guided by a respect for nature and the environment that has always been central to how they work.

The result is tangible: since the 2020 vintage, the entire estate holds the Organic Agriculture certification. A milestone that validates years of commitment and gives lovers of organic Bordeaux wines a sincere, coherent estate whose conviction came well before the label.

Grape varieties and appellations

The estate produces under two complementary appellations. AOC Bordeaux Supérieur for the reds, an appellation that demands higher quality standards than the basic Bordeaux, particularly in terms of yield restrictions and minimum ageing. AOC Entre-Deux-Mers for the whites, one of the most respected white appellations in the Bordeaux wine region, situated between the Garonne and the Dordogne rivers.

This dual identity, characterful reds and fresh whites, allows the estate to offer wines suited to every occasion, throughout a meal and in all circumstances, as Catherine and Dominique Guffond themselves describe it.

The wine style

The wines of Château Le Sèpe are quality wines designed to accompany a meal from start to finish. Not wines built for show, but honest, well-made bottles that hold their own at a Bordeaux table or any table in France.

The gold medal won with the very first vintage is the clearest possible evidence: the quality was already there before the reputation was built. A strong signal that says a great deal about the training and rigour that Catherine and Dominique Guffond brought with them when they took over the estate in 2009.

What you will only find at Château Le Sèpe

Certified organic since the 2020 vintage, committed since 2017. The certification did not arrive as a communication exercise. It is the result of three years of rigorous conversion, launched in 2017. When you open a bottle from the 2020 vintage or more recent, you are holding an organic Bordeaux wine whose commitment predates its label.

At the gates of Saint-Émilion, without the Saint-Émilion price tag. Sainte-Radegonde borders one of the most prestigious, and most expensive, appellations in the world. This estate offers the geographical proximity, the quality of the Right Bank Bordeaux terroir, and award-winning wines from the very first vintage, at a price-to-quality ratio that its famous neighbours can no longer match.

Red and white: two appellations, one level of commitment. Bordeaux Supérieur for the reds, Entre-Deux-Mers for the whites, the estate covers the full range of a complete Bordeaux meal, from the first glass to the cheese course, with the same organic rigour on every cuvée.

A gold medal at the very first vintage. This is not an anecdote, it is a statement of level. The Concours des Vins de Bordeaux is one of the most selective wine competitions in France. Being recognised at the first attempt says everything about the training and precision that Catherine and Dominique Guffond brought with them when they took over in 2009.
