Marteaux Guillaume

Marteaux Guillaume is a winery from Bonneil, a small village that is a UNESCO World Heritage Site. In 2003, after completing his oenology studies, Guillaume took over the family business in the fifth generation. At that time, the vineyards comprised only 75 ares (0.75 hectares). Today, the vineyard covers 8 hectares and will be Demeter-certified from the 2023 vintage. The vineyard is located in a natural amphitheatre with an altitude difference of up to 110 metres and an ideal south/south-east exposure. This geographical location protects the vines from very strong winds and offers exciting opportunities to express the terroir with a variety of soil types.

The principles of biodynamic agriculture are applied throughout the farm. Starting with mechanical soil cultivation, through the promotion of biodiversity in and around the vineyards, including insect hotels, to the use of biodynamic preparations. In the wine cellar, Guillaume favours gentle vinification and spontaneous fermentation with natural yeast strains. Even the labels are made from recycled wood

The powerful and expressive champagnes are the result of five decades of family winemaking tradition, combined with modern techniques and a strong commitment to holistic practices
