Champagne Castelger is located in the heart of a wine village just 6 km west of Epernay. From here they have a view of the Marne valley.

Castelger is a family-run Champagne house, where today it is the 5th generation that is responsible for everything regarding the Champagne house's operation, incl. their 9 hectares of vines. The house is located on the northern hillside of the Marne valley.

Their vines benefit from a semi-continental climate and clay-limestone soil. The cultivation methods are practiced in a traditional way.

They have chosen to produce Champagne with the three main grape varieties, Meunier and Chardonnay, which make up a very large part of their yield (46% and 44%) against only 10% of Pinot Noir.
