Champagne merchants were trying to keep a modest activity in these tough conditions, but they couldn't get grapes in the nearby vineyards.
In order not to lose his 1916 paltry harvest, Jean Cattier decided to produce his own champagne.
Jean Cattier was then considered as a precursor for two main reasons : creating a cuvée that was both a clos and a prestigious champagne.
The cellars of Champagne Cattier are located in Rilly-la-Montagne, with a storage capacity of 2 million bottles.
Historically the depth of Champagne cellars is estimated by the number of steps, since no one has bothered to measure it.
