I have tasted Aquavit that has been stored well over 10 years that still
was quite good. However if the bottle were be opened and kept for a long
time after that, the oxygen in the air that enters the bottle might
react with some of the essential oils from seeds used to flavor aquavat.
This might cause a change in taste, just as seeds can lose taste if
exposed to air over a long time. However this is just a theory, as I
have not opened a botte and then not finished it for many years.
