I just bought a box at an old tavern auction with 4 bottles of bourbon that are at least 20 years old. I got hold of a friend with a gun, and we took turns holding it on each other until a bottle was half gone.
No, but seriously , it seems fine to me. Even though the cap ring and seals where unbroken, the cap seemed a little loose, but there was no noticeable loss of content, it's very clear, and tast fine.
