Finished my 1986 Talisker last night

Finished my 1986 Talisker scotch, now on to my 1990. I have some Talisker "10 year" but I don't know when it was bottled, and some Johnny Walker Green that is 15 years. Does it get any smoother after it is bottled, or does that stop after it leaves the barrel? Either way its a nice way to end the day :)
