I've seen many warnings on the web about storing whisky like this (but with contents and cork intact):
They say the spirit will eventually eat into the cork, making the whisky "corked". I understand this concept.
However, does anyone have any hands-on info on how long a bottle has to be stored in this way for the consumer to be able to tell the difference? It seems people will not hesitate to bring whisky in their luggage on long journeys, or order it through the mail. In both cases the whisky will more than likely be in contact with the cork for long(ish) periods of time, perhaps many days.
So I guess a week on its side will not destroy a whisky. But how long does it take? A month? Six? A year? Any experiences to share?
