This group of companies has worked together since 1872. The four cooperative cellars farm vineyards the length and breadth of the Loire. Their most recent output was an impressive 33 million bottles. The group has always made sustainability one of their priorities. It boils down to having a fully traceable agricultural and manufacturing process. So the low-yielding, old vine Sancerre has the same level of traceability as the EDLP Vin de France.
