In line with Champagne tradition, Charles Heidsieck owns and cultivates some sixty hectares, divided between the Marne and Aube departments. Long-term contracts with winegrowers and cooperatives in Champagne complete its requirements for supplies. A responsibility for the House, which is in charge of making the best of the grapes harvested. Pride for the winegrower who participates in producing a wine appreciated on the very best tables throughout the world.
A constant focus on conserving the lands and practices that protect the ecosystem has led to recognition of the House vineyards for its sustainable viticulture. It has also been granted High Environmental Value status. Comprising 123 points, this programme is both demanding and complete, going from soil and vineyard nutrition, maintenance of the soil and management of the vines to waste management.
