I was given a 50 year oldbottle of Don Pedro brandy. The cap is still on it. It even has a “rattle” inside of the cap. I was told that it has was never opened but leaked a little from the cap a few years ago from being laid on its side for so long. Is this safe to drink? I do t want to getting sick from another bad bottle. Had some bad wine once and puked some crazy looking shit! More worried about the air getting in and it being “spoiled”. How can I check?
