My father in law is trying to get a bottle of Scotch from every distillery. I believe eventually including some that have closed. So far he accidentally bought one duplicate, which he gave me, so I support it!
I actually finished an architecture project for William Grants recently (Grants Whiskey, Hendricks Gin, Sailor Jerry's, etc) and these guys do NOT mess about. I was showing the client around the building when it was finished and he asked for extra locks on one of the showroom cupboards. A single bottle in there was £30,000 (Balvenie 50 Year Old)
