The Déthunes started as growers in the early 1800s and began to make their own Champagne in the 1930s. The vineyards are planted in the ratio of 70% Pinot Noir to 30% Chardonnay and are farmed on organic principles – and hold the highest level HEV (High Environmental Value) certificate for sustainable viticulture. This immaculate 7-hectare domaine goes from strength to strength. Pierre and Sophie Déthune are friends of the Fournys and this Ambonnay domaine is amongst the loveliest and best cared for in the whole of Champagne.
