What should we do with opened bottles? Someone told me that the taste starts to go after 6-12 months. That doesn't bother me with my regulars, but I'm now accumulating and tasting more and more and even have a bottle of Distiller's Masterpiece and a few WT Tributes that I just found and don't want to open them if I need to "run" through them in six months.
Would a good idea be to use those wine stoppers where you suck out the air and create a partial vacuum? They definitely enable bottled wine to last longer.
Would a good idea be to refrigerate, e.g. in wine cooler?
I'm not sure it's scientific, but I do think my whiskey changes a little with breathing.
