Sediment In Unopened Bottle

I was given by my parents a bottle of Hedges and Butler Royal DeLuxe Scotch Whiskey for my birthday.
I have noticed the bottle has some sediment in it. It has been stored in a cellar for all it life since my parents bought it many years ago.
The bottle has not yet been opened.
Is the Scotch still good, is this common and if so what is the best way to remove it, if it is preferable.
The bottle is label as product of Scotland, bottled in Australia.

Looking for to all suggestions.
