I bought this 10 yo bushmills but when I opened it and tasted the whiskey (same day as I bought the whiskey) there was something weird about the taste. It was a waterlike taste, no warmth or after taste in the whiskey. There was clearly alcohol in it but the normal taste seemed to be missing. I then was adviced by my mate to shake the bottle and then most of the taste seemed to come back. But still a unusual taste for a 10 yo bushmill. I then left the bottle for a week and the same thing happend again.
Could it be that the whiskey have been exposed to high or low temperatures? or something else? anyone got an idea?
