In Celles-sur-Ource, in the heart of the Côte des Bar, Anne (agricultural engineer) and Étienne Sandrin (lawyer) decided in 2006 to take over the vineyards of the Sandrin family, converting to organic and then biodynamic viticulture from 2013. For generations, the Sandrin family have sold their grapes to the local cooperative, but since 2014 they decided to start making wine from part of their production, mainly for themselves and for a close circle of friends and enthusiasts with the same quality requirements.
