March 2017: I vinify [my wines], I raise them and then one day I decide to bottle them; and there, the bottle, the closure, the capsule, the label, the box or the carton, everything must be taken into consideration. Among these five elements, it is on the cork that I spend the most money. It is the most important element.”

Now we have DIAM who are revolutionising the closure! When I open wines that I corked 5 years ago, ‘Un esprit de chevalier’ 2012 for example, the 12 bottles are identical. They are all fresh, pure; they have kept their original character.

In my opinion, 90% of Bordeaux wines should today be sealed with these so-called technical closures.
