The name of the winery originated from the marriage of Yves Pertois and Janine Moriset. Both come from old winemaking families of the Côte des Blancs. In 1951, the two decided to market Champagne under their own name in Mesnil-sur-Oger. Today, the winery is run in the third generation by their granddaughter Cécille and her husband Vincent. It now extends over 12 hectares of Chardonnay-planted vineyards in the Côte des Blancs as well as 6.5 hectares of Pinot Noir and Chardonnay-planted vineyards in the Coteaux Sézannais. These vineyards are carefully tended without dogmatically adhering to any philosophy. In 2009, comprehensive investments were made in equipment, the cuverie, and cellar technology. Today, precise temperature control prevents malolactic fermentation to capture the typical freshness of the Côte des Blancs.
