I've previously read elsewhere that opened bottles of bourbon will deteriorate over time due to exposure to air. The information indicated that the longer the bottle had been opened, the greater the chance that "off flavors" would occur with the remaining bourbon. I have never personally experienced any problems with any deterioration of opened bottles. Has anyone ever had this problem? If so, how long had the bottle been opened? How much bourbon was left in the bottle?

I tend to like trying my new purchases, and then casually go about enjoying them over time. I ask these questions, because I'd hate for my opened bottles good bourbon to become not-so-good.

Have a great Wild Turkey Day! Happy Thanksgiving!
