OK, Jack.
Here's one of my favourites.
Most whiskies are blends ( think Johnnie Walker etc )
Rarer whiskies are Single Malt whiskies ( all constituents are from the one distillery ).
Even rarer are Single Cask, Single Malt whiskies.
Literally just the contents of one gem of a cask, selected by the wise folk at the distillery ( or bottler ).
Sometimes the vagaries of the maturation process throw up a gem, for unknown reasons.
Single Cask Whiskies are usually only obtainable from specialist retailers, or from Whisky Clubs.
I had the good fortune some years ago to acquire 2 each of 2 fine Single Cask bottles.
Details are available on request.
Yes, I shared one of each, with like minded friends.
Persuing international auction sites, showed that prices of these 2 rarities were rising sharply.
So I sent them off ( with a wee twinge ).
The auction result was pleasing with a capital P.
My wife and I flew to Europe, spent a few weeks travelling, enjoyed a 10 day cruise, travelled a further fortnight, and came home again.
All courtesy of just 2 bottles, that originally cost about $100 each.
No skill involved, simply pure dumb luck.
