If they are selling the 20 year stuff for a hundred bucks a bottle, I shrudder to see what they will sell the 450 year stuff for.
The title is poorly worded.
Unless you count residue they didn’t find actual whisky. The Scott’s drank all that ages ago.
Unlike wine, whisky and Scotch stop aging once they are bottled. if you bought a bottle of 20-year-old whisky 50 years ago, you do not have 70-year-old whisky. You have a 50-year-old bottle of 20-year-old whisky.
Whiskey doesn’t get any better after about 20 years. It may even get worse.
