Jacques Selosse is a Grower Champagne, which means the grapes used to produce the wines are grown in vineyards owned by the winery rather than being purchased from other growers, as is the case in most Champagne production. The entire production is grown according to biodynamic principles and Anselme is considered a pioneer of biodynamics in Champagne. Selosse wines are fermented using oak barrels, in contrast to the majority of Champagne producers who use stainless steel tanks.
Two of the wines in Selosse's range, the Substance and the Contraste, are produced using a solera system, the same process used in Sherry production.
Selosse holds 37 acres (15 ha) of vines, predominantly Chardonnay with the remainder Pinot Noir. Around 55.000 bottles are produced each vintage, dependent on conditions.
