Sad, sad news.
Christian was one of the founder of the natural wine party, and one of the few that had rational and argumented perspectives on natural winemaking.
We had great discussions, you know, when you go to sleep with the feeling to be more clever than when you waked up...
But more than that, Christian and Nathalie made "des vins jolis", like Chauvet would have said.
I'll miss him.
