I have been recently using number 8 corks in my wine and after doing some reading Ive been hearing alot about not being able to age wine unless your using a number 9 cork. I was just wondering how valid this is, my bottles have never leaked with the number 8 corks and the liquid never goes above the bottom of the cork.... I was wondering if anybody could show me some proof that oxidiation occurs faster with the 8s then the 9s.The wine I am making now we be consumed in less then 2 years, is this too long to be using the number 8 corks???
