Greetings everyone, from a new guy ~

I suspect this has been asked more than once, however, I did a search and still haven't quite found what I'm looking for.

Anyway, my question is really two-part.

I was recently given (yesterday) an opened bottle of Jack Daniel's. The whiskey was originally bottled approximately 30 years ago but was never actually opened until somewhere around 5-6 years ago. And when I received it the bottle was a little more than 2/3 full.

So, I'd like to get opinions on *whether or not it is still drinkable* ... certainly from a "general quality" standpoint, but equally important, also from an "any 'health concerns' standpoint" (hope that makes sense) given the ages involved.

How has this whiskey been affected:

1. from the 0-25yr mark - unopened.

2. from the 25-30yr mark - opened.

And really #3. the two time frames combined ?

Thanks for your input - I really appreciate it.
