Can you guys please elaborate on this? I have never had a bottle of bourbon go "weird" on me in the slightest. The closest I've seen to this phenomenon is a bottle getting a little "tired" after being open for more than a year.
Opening up sure seems to help Old Forester Signature; the "nose" improves significantly.
That's been my experience too.
I have had no problems so far with long open bottles either. I would only note that it is worthwhile to check the status of the cork periodically in bottles with real corks because they can dry out and no longer seal well. I have lost at least one bottle to this problem in the past. I am liking the idea of the good quality screw top closures typically found on Japanese whiskey more and more. Not likely to have an issue with those.
With some of my bottles that are less than half full I have put the vacuvin Wine style stoppers on them. What is the consensus on this? It definitely removes all the air from the bottle but I also wonder if this also removes some of the alcohol vapor and if that is more detrimental than having a lot of air in there. Overall I have not noticed any issues but not sure what long term affect this may have.
Couldn't hurt I suppose but I would probably need a hundred of the damned things and that ain't happening!
I'll just drink them up and be happy.
Haven't noticed any change in mine that have been opened a year but occaisionally one will taste different than it did originally but I atest that to me and I feel is more related to what I have eaten or maybe just the mood I'm in.
