Chanterêves is the project of husband and wife Tomoko Kuriyama and Guillaume Bott, founded in Savigny-lès-Beaune in 2010 after careers at Etienne Sauzet, Simon Bize, and Weingut Altenkirch. Both trained in oenology—Tomoko in Germany, Guillaume in Burgundy—and met during harvest at Simon Bize, where their shared instinct for purity and restraint became the foundation of everything that followed. "We both like purity and elegance," Tomoko has said. They make wine by infusion rather than extraction, letting the fruit steep gently in its own juice; as The Feiring Line put it, wines of infusion "wash over you like a breeze instead of a heat blast." In 2020 they acquired 4.9 hectares of their own vines across Savigny, Chorey, and the Hautes Côtes de Beaune, and what began as a négoce has grown into one of the Côte de Beaune's most closely watched domaines. 

Mainbey is the largest lieu-dit in the domaine, a stony, high-altitude site on the slope of a valley adjacent to the village of Fussey, at 470 meters, with big blocks of limestone running through the soil. The aligoté parcel here was planted in 1980 and is farmed organically with biodynamic methods. Vinification follows the house approach for whites: whole-cluster press over six hours, indigenous yeast fermentation with a pied de cuve, aged in 228L and 600L used barrels, no fining and occasional light filtration.

The distinction of this bottling is its élevage: where the standard Mainbey aligoté ages ten to twelve months in barrel, this portion was set aside in 2023 for a full 22-month barrel élevage before release. The result is a wine of remarkable dimension: notes of lemon curd, toasted almond, and the chalky mineral tension that runs through everything from this site.
