Few companies, in Switzerland or elsewhere, can boast D'Auvernier's 400 years of family history. Keeping the estate in the family has always been a priority. Today, owner Thierry Grosjean, is reorganizing the estate and introducing integrated culture, a respectful approach to the environment which makes it possible to decrease the spreading of chemicals and spare the soil. In 1999, a barrel storeroom was built with 220-litre barrels for certain wine specialties matured "in the cask."

Owner Thierry Grosjean endeavors to promote the image of Neuchâtel wines. He has great confidence in the resources of the Neuchâtel vineyard and believes in its future. Apart from its wine-producing image, he considers Auvernier Castle part of the history of the village and surrounding area, a commitment that goes beyond the mere production of wine.

This estate is located on the shores of the Lake of Neuchâtel and currently markets the produce of about 60 hectares of grapevines. Although the Auvernier Castle Cellars actually possess only 16 hectares of grapevines, they cultivate an additional 24 hectares and buy the harvest of 20 hectares more from vine growers with whom their ties, in some cases, go back several generations. Geologically similar to the Burgundy soil, although situated a little further south, it benefits from the proximity of the lake, which regulates the temperatures, thereby offsetting the additional 100 metres or so in relation to its French counterpart.
