The house cultivates 89 hectares of vineyards on the best DOCs of the Loire Valley (45 in Saumur, 11 Ha in Saumur Champigny and 33 Ha in Sancerre). The vineyard is fully certified Terra Vitis (sustainable viticulture). Sparkling wines, with Crémants de Loire, have been a big part of the success of the Langlois-Chateau. Bollinger family ownership since 1973 is also a key involvement. With an international scale and a very high reputation, all the elements are in place to be one of the most famous houses in the Loire Valley.
