The Pertois-Lebrun house was created through the marriage of Paul Pertois and Françoise Lebrun, who combined their families' vineyards in 1955. Their daughter Odile took over the management of the winery. She was succeeded in the fifth generation by her nephews Clément and Antoine.

The two brothers, who grew up in Provence, complement each other perfectly. Clément is the nature lover who is converting the 44 parcels and 9.5 hectares in the Grand Cru villages of Cramant, Le Mesnil-Sur-Oger, Chouilly, Oger, and Oiry to organic farming, Antoine gave up his career as a management consultant and takes care of the business management matters.

The excellent grape material from the old vineyards is now vinified at the winery depending on the cuvée in stainless steel, wood, or sandstone amphorae. The brothers produce exclusively Blanc de Blancs Grand Cru with a lot of pressure, minerality, liveliness, and aromatic precision.
