I was aware, and Bertrand's article confirms this, that Didier, like Claude Papin and others, has grave doubts about turning the soil over and thus destroying its profile.
Didier is nearing retirement – he and Catherine Roussel have reduced the size of Le Clos Roche Blanche to nine hectares – and he intends to concentrate on his work in the vineyard. It would be good to see Didier set up a website or a blog to spread his ideas and findings to a wider audience.
See also here comments on Bertrand's article on the Clos du Porteau blog – Aynard is very concerned by the threat that esca poses to his Sauvignon Blanc.
Also a very brief report here on the Porteau blog on Esprit Vif held yesterday at Château des Couldraies in Saint-Georges-sur-Cher. It appears to have been a success.
(This post was originally tacked onto the my previous post but I think it makes more sense to post this separately.)
