Burgundy negociant house with cellars in Meursault and a bottling plant at Vignoles outside Beaune, part of the Helfrich family's Les Grands Chais de France since 2015; the Vignoles plant also bottles EU-blend labels such as Marquis de Blanc.
Maison François Martenot traces itself, on its own site, to a 10 ha estate in Savigny-lès-Beaune created in 1859 by Léonce Bocquet, owner of the Château du Clos de Vougeot, and bought in July 1922 by Lucien Gustave Martenot, whose daughter Charlotte ran the house after him. In 2015 the Helfrich family, owners of Les Grands Chais de France, acquired it: the French company registry lists SAS François Martenot at 6 rue du Docteur Barolet in Vignoles, shows Patrick Tresch as president until Joseph Helfrich replaced him in December 2015, and records the absorption of Pasquier Desvignes, Moillard-Grivot, Moingeon La Maison du Crémant, Maison Desvignes Ainé et Fils and Béjot Vins et Terroirs. Trade press describes it as Les Grands Chais de France's Burgundy subsidiary, reorganised after the group's acquisitions of Tresch (2015) and of Paul Sapin and Béjot Vins et Terroirs (2016). The house says it owns 13 estates covering 270 ha from Chablis to the Mâconnais and Beaujolais, with eight vinification sites across Burgundy, an ageing cellar in Savigny-lès-Beaune and a bottling plant in Vignoles, and it groups Maison Moillard, Reine Pédauque and Chartron et Trébuchet under its umbrella, producing Burgundy and Beaujolais appellations plus Crémant de Bourgogne. The Vignoles plant also bottles labels outside Burgundy, such as the Vin de l'Union Européenne Marquis de Blanc, which does not appear on the house's own website.
