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?
Thank you!

I've frozen bottles of vermouth many times. There is no issue with just letting it thaw out in the normal way. In fact you can wait until it's partly thawed, give it a good shake, and hey presto, vermouth slushy, which goes in some cocktails rather well. Fortified wines do slowly oxidise on exposure to the atmosphere, but this is greatly slowed by the alcohol content. Historically this was one the principle reasons for fortifying wines - so that they store better and last longer.
