I accidentally froze an unopened bottle of white Vermouth. I've read that opening the bottle will cause the vermouth to slowly oxidase and you should finish the bottle within a month or so. How is it with a frozen bottle - does that matter?
What about regular wine? Will the freezing/thawing of a bottle reduce how long it will stay OK for drinking or can I simply thaw it up slowly and treat it as if it was never frozen?
