Johnny Walker Red Label How Old Is My Bottle Of Johnny Walker Red Label?

How old is my bottle of Johnny Walker Red Label? - johnny walker red label

I was given a sealed bottle of Johnny Walker Red Label from my grandfather, who was five years old. He got to a bottle with an old friend who had for a while. I wonder if it does not know the age of the bottle, because it is a remarkable amount that has disappeared into thin air, but it remains closed. Thank you for your time.
