As long as they are still sealed they are fine.
I’ll test out a bottle or two for you if you don’t trust them. :)

I’m figuring things like saturnes and trockenbeerenausleses are okay. But I’m thinking that the rieslings and chardonnays might not make it. And I’m unsure of merlots and pinot noirs. We had a case of vintage grape juice for me from 1986 and we threw all of them out based on one bottle.
