Whiskey Flask

how long can i leave whiskey in my flask without it going bad?

Some alcohol does go bad, be careful to always read the expiration date on your beer to make sure you drink it in time! (As if anyone has a problem with that haha)

But to answer your question, Whiskey will not go bad, it'll only begin to turn into scotch, so the question is what is your flask made of? If it is a lower-quality metal, the whiskey will begin to have a metally taste after probably a week or so. If it is high quality metal, you got a month, TOPS.
