In 1985, Paul-François bought Château des Castaignes in Montmort, built on a site known as La Demoiselle in Montmort, a few kilometres from Epernay.

The château stands on a hillside, at the heart of a park designed by Edouard Redont, who also designed the park of Villa Demoiselle.

The idea arose to create a new cuvée for Champagne Vranken, called La Demoiselle de Champagne. "Demoiselle" was the common name for a dragonfly, a symbol of the Art Nouveau genius René Lalique.
Everything came together to create the first brut champagne, whose distinctive bottle was a moving tribute to Art Nouveau.

At the turn of the century, Henry Vasnier, founder of Villa Demoiselle, chose this location for its view of Reims Cathedral.

Henry Vasnier was named universal legatee of Maison Pommery following the owner's death in 1890. A prolific art collector, he donated a fantastic collection to the Museum of Fine Arts in Reims.

He encouraged Madame Pommery to purchase Millet's Les Glaneuses and to commission works from Émile Gallé. He also called on members of the "L'Art Dans Tout" group (Art in Everything) to create the most modern house built at that time.

All the splendor of this early 20th-century architectural treasure was given fresh momentum in 2008, thanks to the passion of its owners, Paul-François and Nathalie Vranken.

Villa Demoiselle is a unique testament to the joint endeavor of a group of architects, cabinetmakers, and decorators, united by a common goal and drawing their inspiration from Art Nouveau and Art Deco.

In 2009, after two years of work, the cellar takes pride in an exceptional collection of rare 20th-century vintages assembled by the Champagne House Vranken: Millésimes d'Or, the oldest of which dates from 1907. The kiosk, renovated in the same spirit as the mansion, between Art Nouveau and Art Deco, welcomes visitors and houses a boutique reserved for prestige sales.

The garden was redesigned in 1909 to plans by landscape architect Edouard Redont. In his native city of Reims, Edouard Redont created Parc Pommery, today known as Parc de Champagne, a 70-hectare estate. He was also involved in designing the garden of Château des Castaignes.
