Scotch lovers asked to cough up £10,000 per bottle
"each occasion they enjoy a dram"?
"each bottle will be hand-blown and presented in hand-stitched, leather-bound cases. Alongside the bottle, a leather-bound book will detail the whisky's history and enable owners to record personal tasting notes for each occasion they enjoy a dram."
Whisky oxidises in the presence of air, and there's enough air in a typically half-empty bottle to make a noticeable change to the taste; savoury Islay malts turn sweet. I don't generally drink that much Highland malt such as Glenfiddich so while I reckon it would change from sweet to sweeter, I can't say so from experience.
Generally then, once you've opened a bottle, if you want it to taste right, you need to polish it off. The dregs in a near empty bottle you've had for years will taste completely different to what the distillery's chief taster intended....
... so unless you have some fancy system to flush the airspace inside the bottle with nitrogen before shoving the cork back in, drinking one's £10k bottle nip by nip over several years is probably a flawed idea.
