I recently found six bottles of 1970 Château Lynch-Bages (Pauillac) in my 94-year-old grandmother’s cold storage.

The bottles were stored on their side and, as far as we can tell, have likely been untouched for at least 30 years. I do not have much experience with wines of this age and am looking for some guidance.

I plan to drink them rather than sell. Wine is meant to be enjoyed. That said, I would appreciate any insight on approximate value, how to assess whether they are still sound, and best practices for opening and serving something this old.

Any advice is welcome, and thanks in advance.
