Corks and wine oxidation
Maybe corks are more magical than we thought, and as they change in time they preserve the wine. UC Davis University will study them for 100 years

Cork – Fattoria del Colle infernotto-

<<An experiment that maybe will last more than life on earth>>commented W. Blake Gray while talking to Wine searcher about the study going on in the major US agriculture university, the awesome UC Davis from where the majority of great American winemakers come out from.
To carry our an experiment that lasts 100 years is in fact something very difficult to understand in our society based on rapidity and now. It actually quite reminds one of the empiricism of the 18 hundreds, but that might be why it is well suited to a type of closure, that in the XVIII century, was perfected: the closure for glass wine bottles .The experiment starts from a mystery: why the oxygen that penetrates through the cork, one milligram per year, does not oxidize the wine?

We might think that it is the sulphur dioxide that gets inserted in the bottle (generally 20-25 milligrams per litre) that protects the wine, but it is in fact the oxygen that uses it up during 5-6 years, and so 10 years and more later there is nothing left to defend the nectar, as explained by professor Andy Waterhouse author of this intrepid research project regarding cork closures and wine oxidation.
