BenRiach 1966 Rare Reserve.
This one has kind of a cool story, bro. Shared by one of the owners of the distillery, a South African guy with whom I play golf. Made his very, very considerable coin by -- among other things -- selling single-serving sachets (think McDonalds ketchup packets) of cheap booze up into more equatorial Africa. Biggest mover is kind of a Baileys-type goop of industrial moonshine whisky and ultra pasteurized dairy. Yum yum.
Anyway, the Scotch Whisky Association comes to them one day in the early oughts and says something along the lines of: "It has come to our notice that you are now among the major purveyors of alleged "Scotch" on this benighted subcontinent. It might behoove you, should you not wish to encounter all sorts of trademark etc. issues, to legitimize yourselves among your peers by picking up a genuine operation -- and by the way, we just happen to have one in mothballs we can sell you. Bit of a mess, but think of the potential. You chaps already seem quite handy at marketing to the heathen, eh? Asia! Growth!"
So they buy the place pretty much sight unseen for around $10 million and install some competent management, who then go through the premises and records carefully and find out that they actually own several thousand more casks of real good stuff than were ever accounted for. Total estimated value of said casks -- around $10 million. Free distillery! Good times.
