The thing that distinguishes Diam closures from others produced from "bits", aside from their CO2 treatment, is their porosity rating for O2 permeability and transfer. They have corks rated from 2 to 10 years, based upon probability of oxidation. They make no claim that their O2 permeability approaches the rate of natural punched-and-finished cork.
Craig Winchell wrote:Oliver, cork permeability is neither good nor bad, in my opinion, it just is. It certainly seems to help promote certain kinds of chemical reactions in aging, and also seems to be a factor in oxidation under certain conditions. I was only saying that in the case of Diams, they have things down to the point that they assign different Diam corks to different types of wine, based upon the perceived ageability of the wine, and therefore how long one can expect that wine wine package will remain intact until drinking.
