Absolutely...and it will taste exactly the same as it did 100 years ago. Glass is non-reactive, so the whiskey has not “aged” or “matured” in any way....what would have been fantastic is had it been in a oak cask..not that would be awesome..
I suppose this is true with liquor but I would swear shine changes in a jar after some years...course it could be the peach breaking down
Wine of course can get stellar or go bad in glass...is it the cork contact?
this is curious
