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.

Are sulphide-like odours in wines under screwcaps not nearly as big a problem as TCA and random oxidation with cork?
The incidence and intensity of TCA continues to fall and the latest research shows that cork is remarkable consistent in terms of oxygen ingress.
That does not mean that cork producers can relax. Amorim will remain ever vigilant against TCA. Our R&D effort will help us better understand and control oxygen ingress through corks and we will work with winemakers to minimise the risk of ‘random oxidation’ associated with bottling line operations.
While the problem curve for cork is coming down, the problem curve for screwcaps is going up.
Screwcap producers and wine researchers are a long way from knowing how to avoid the sulphide-like odours (SLOs).
More and more questions are being raised about the effect of the screwcap on wine development.
A toast to cork!
