This is a dumb question I'm sure....but I thought I would ask it anyhoos.

Does scotch get better with time after it's bottled?
I'm sure that a 10 year bottled would not taste as good 5 years later as a 15 year would.. but does it age at all after it's glassed?

Further.... after a bottle is opened.... does it tend to lose it's luster once the seal is broken like wine does?

Please do not string me up for not knowing these things....I am a Scot but I'm uneducated in the ways of the brew.
