A boss gave me a present for going above and beyond the call which he had received from a client.
I don't remember the distillery name, but it was a numbered bottle, something like #1800 from a since closed Scottish distillery. 82.5% by volume, single malt. I looked it up on ebay and it was selling for around £180 a bottle.
I drank it after verifying it would light and burn easily. Took me a while and it was potent.
