If you opened the bottle in question 23 years ago and then opened the same bottle today it will be the same.
However a 2009 bottle of a Macallan 12 yr will have slight differences when compared to a 2010 bottle of Macallan 12yr because the different years.
Do you have proof for this?
In my experience, and many experts agree, whisky does change in the bottle
(See for example this article
). I have sampled many whisky bottled in the 70's and 80's, and they all have something similar, what some call Old Bottle Effect.
Silvano Samaroli, a legendary independent bottler, even states on the labels of his whisky: "refined in the bottle".
All I can say is, go find out for yourself, and don't believe everything the marketing departments of the whisky industry tell you.
