The Champagne J. Charpentier estate is located in the Champagne vineyard, in the town of Villers-sous-Châtillon ( 51700 ) in the Marne.

The estate operates an area planted with vines of around 15 hectares. The grape variety consists of white Chardonnay (20%) , black Meunier (60%: dominant grape) and Pinot noir (20%) . The vines generally benefit from a moderate oceanic climate and a degraded continental climate. The soil and subsoil of the Champagne J. Charpentier estate are composed in varying proportions of clay, Campanian chalk (Upper Cretaceous, 70.6 to 83.5 million years ago), Lutetian limestone, Bartonian, Thanetian sands (last period of the Paleocene, 59 million years ago, located between the Selandian and Ypresian), Cuisian sands, Sparnacian clays, Lutetian marls and silts. The estate practices sustainable viticulture .

The grapes are pressed using a traditional wooden Champagne press of 4000 kg. To vinify its grapes, the Champagne J. Charpentier estate applies the traditional Champagne vinification method . Temperature-controlled stainless steel vats are used for the vinification. For all or part of its cuvées, the estate uses undergrowth vinification using oak barrels and oak casks depending on the ability of the musts to hold the wood. The estate practices malo-lactic fermentation for white wine vintages. These then undergo filtrationbut no collage. After the fermentation, a deposit forms in the bottles. To gradually remove it, the estate uses manual riddling on a wooden stand but also depending on the vintages mechanically by gyropalette. Then, after compulsory aging on slats for champagnes (ranging from one year to three years for vintages), the estate proceeds to expel the deposit by disgorging with ice (freezing of the deposit present in the neck of the bottle in a bath at -20 ° or -25 ° C).
