Where does cork come from?
Cork is stripped from the trunk of the Cork Oak every nine years, without damaging the tree. The largest areas of cork oak forest are in Western Mediterranean countries: Portugal, Spain, Italy, France, Morocco, Tunisia and Algeria.
Wines do not need oxygen to age, as Ribéreau-Gayon has demonstrated, so are corks relevant to wine development?
Wines may not need oxygen to develop, but it appears that they benefit from the minute amount of oxygen ingress allowed by cork stoppers.
Where wines have been totally deprived of oxygen, i.e. in glass ampoules, they have also displayed a marked tendency to develop suphide-like odours. So evolution may continue to occur, it just so that it leads to results that are far from what the winemaker originally intended.
The findings of researchers at University of Bordeaux 2 suggest that oxygen diffusion through the natural cork is more important than reported by J. Ribéreau-Gayon in 1933.
Ribéreau-Gayon used a similar colorimetric method, but did not record the characteristics of the closures, the bottles or the storage conditions, factors that Lopes et al. believe would help to partially explain some of the differences between the results of the 1933 and 2005 studies.
