From Martine's website: 

Champagne Saint-Chamant was established in 1930 by Pierre and Hélène Coquillette. Their son, Christian, took over the estate in 1950 and led the production for an impressive 70 years. After Christian passed away in 2020, his son Stéphane succeeded him as the third generation, committed to carrying on the long traditions that have been established here.

Located in Épernay, the house's unsigned, unassuming exterior in no way hints at its labyrinthine cellar, built in the early 19th century, which is a mile long — and lined with hundreds of thousands of carefully aging Champagne bottles. Saint-Charmant specializes primarily in Blanc de Blancs with more than 28 acres of Chardonnay vineyards in the Chouilly Grand Cru. The house also crafts a limited amount of rosé made with a small percentage of Pinot Meunier grown on a ½-hectare plot in Épernay. Stéphane is a firm believer in extended lees aging, and he disgorges only once the wines have been ordered.
