My grandparents were given a bottle of wine on the day I was born in 1983. We were going to open it for the holidays this year but before we did I went on the internet for some brief information and found it to be a rare bottle of wine. We are going to wait and open it on my wedding day. My question is how do I properly care for it? Will it matter now that it has likely not been properly cared for previously? The bottle of wine is a 1959 Château Latour Grand Vin (France, Bordeaux, Médoc, Pauillac) I appreciate any advice.

Thank you

Honestly this will be passed it's best, but still drinkable assume proper storage.
While it is indeed extremely rare, unless it has be properly cellared with documented providence is actual value will be greatly reduced.

My advice, crack it open and enjoy a small piece of history..
