I recently found and bought a bottle of Black Bush that was bottled in 2005 (before Pernod Ricard sold BUshmills to Diageo) and came in the metal tube box. I find it to be a quite delicious Irish whiskey to sip.
The liquor store that had it, has one more bottle of the same vintage left, and I was curious if there is any value in buying that one also to stash away for a rainy day? The shop that has it, will probably not sell it for a very long time, the two metal tube containers were covered with half a decade of dust. It's the kind of store that nowadays sells mostly cheap booze to its welfare-recipient customers. The upper shelf spririts inventory is left over from previous owners and more prosperous times from many years ago, and the new owner of the shop is pretty much clueless about any whiskeys above and beyond those that come in a plastic squeeze bottle.
