Billecart-Salmon is a medium-sized champagne house in Mareuil-sur-Ay, France. Founded in 1818 with the marriage of Nicolas François Billecart and Elisabeth Salmon, it is one of the few to remain family owned.

The Cuvee Nicolas-Francois Billecart 1959 won first place in the Champagne of the Millennium 1999, out of 150 of the finest 20th century champagnes. A magnum of the winning champagne later sold for £3,300.

Most of Billecart-Salmon's fruit comes from a small vineyard holding, though this is supplemented with grapes bought in from the Marne Valley and the Montagne de Reims. Meticulous production techniques, from the use of their own cultured yeast to its long, slow, cool fermentation, ensure that the family has 100% control of production.

Billecart-Salmon is renowned for the quality of its delicate rosé, while the Brut Réserve (a blend of three vintages) is a beautifully harmonious and balanced wine.
