I have about 3-4 bottles that have been opened for over a year. They have contained less than 1/3 bottle for over 6 months. I'm really not too worried about it. I don't stress out about timeframes. I bet Hunts and Pio have many, many open bottles. Edit: I have to admit, my Balvenie 21 has lost some of its luster (open for over 6 months and been mostly empty for 4 months). I have about 30ish bottles open right now. The exceedingly rare/expensive stuff I re-bottle when they get down to about half. (Old Hudson bottles are great for that purpose, by the way.) The rest I just let go and when they get way down drink a little quicker or have a few friends over to help me finish. Had a pour a laphroaig 10 tonight. Interesting to say the least. Very earthy. Not sure if scotch is for me Its an acquired taste, if you like smokey, but not too smokey, you might want to try Lagavulin or even that Laohroaig Quarter Cask. They are both great smokey scotches, but a little more tame.
