Yvonne Seier Christensen

Yvonne Seier Christensen founded her champagne house in 2017 and runs it under the name Maison Les Cinq Filles. The Danish-Nigerian winemaker and entrepreneur did not take over an old family estate but built her brand herself. The name says it all: Les Cinq Filles is a legacy she wants to pass on to her five daughters. She is registered as a Négociant Manipulant and holds a Bachelor's degree in Viticulture and Oenology.

The house in Le Mesnil-sur-Oger

The house is based in Le Mesnil-sur-Oger, one of the most important grand cru villages of the Côte des Blancs. The address is 22 Avenue de la République. The village's chalk soils produce 100% Chardonnay blanc de blancs grand cru with pronounced minerality. According to the house, every bottle is vinified by Yvonne in her own house, from hand-picked grapes from grand cru parcels in the Côte des Blancs. The house says it stands in a stone building dating from 1879. There, by its own account, a basket press about 100 years old has been restored for traditional, gravity-driven production.

Vineyard in Avize and way of working

The house's own vineyard is in Avize. It is worked with horse-drawn ploughs, and Yvonne Seier Christensen also uses traditional organic methods to protect biodiversity. The house aims for sustainable, organic and biodynamic methods wherever possible. The cuvées are low in dosage or have none at all, and age for a long time on the lees. The house describes the wines as five grand cru cuvées. The pinot noir for the rosé, however, does not come from the Côte des Blancs: it is 100% organically grown, from further south in the Aube.
