My family and I were going through my grandmother’s apartment after her passing to get her estate in order. After all was said and done, I got a bunch of alcohol she had for guests mostly, including two types of whiskey (scotch and regular), some gin, and three flavors of vodka. I tried some of the Crown Royal and it didn’t taste too good. Also didn’t taste like the last glass of whiskey I had before. Of course I always hear about stuff aged 4 years or 12 years etc. so I wonder if it’s a “gone bad” thing or a me thing.
Alcohol can’t expire, expiration is a part of how it’s made. In most of these cases the expiration date is actually for the container.
If the container looks fine and nothing has gotten into it, it’s no more dangerous to you than alcohol normally is. Same goes for vinegar and many other similar things. For example honey can’t go bad in a sealed bottle, but the bottle can degrade and let things in.
This is not exactly true, alcohol can become vinegar if exposed to oxygen, and I doubt those bottles are properly hermetically sealed.
