What is cork?
Cork is the bark of the Cork Oak tree (Quercus suber L). It is an all natural raw material, with unique properties which give it an unparalleled character. It is light, impermeable to liquids and gases, elastic, compressible, provides thermal and acoustic insulation, a fire retardant and highly abrasion-resistant. Furthermore, it is completely biodegradable, renewable and recyclable.
As knowledge of wine chemistry advances, will it be possible to determine the desired amount of post bottling oxygen ingress for any wine and choose a screwcap or technical cork of a particular permeability to suit?
Post-bottling wine chemistry is a very complex issue and we are still a long way from understanding all the factors at play let alone controlling them for each wine style, region and vintage. Cork, on the other hand, has been doing a remarkably good job for centuries. As we understand it better we are able to further improve its performance.
“To try and make one extremely low permeability closure to suit all wines is going to lead to variability of results not between individual bottles, but wine to wine.… To require wines to be completely free of any sulphide precursors will place demands which at this point in time we are unable to (and may not wish to) consistently fulfil as winemakers.
