My late father was, and the wife and I regularly received 'special' bottles from him, via whatever club he was a member of. They always came with a note saying 'this one is special...at least read the label before quaffing' or words to that effect.
Back in the early 80's, he had bought us a box of twelve 'special' wines as a wedding present. He visited us not that long after, and in the evening asked if we would mind opening one of these 'special' bottles he had given us. He was rather upset when Jane informed him that all twelve bottles had been necked pretty much within a week of us receiving them. Apparently he had gone to an enormous amount of trouble and research in choosing each individual wine, and had intended them to be used for birthdays, anniversaries etc. He was even less impressed when he asked us what we thought of each wine only to be informed, with the best level of fine wine critique we could come up with, that 'we loved the red, but we gave the white to our sister'. As was his way, he did his best to educate, encourage and inspire in all things vin, but to this day we stay with what we know....if its less than a tenner and doesn't have the ability to eat its way through three decks of Nostromo, we will probably buy it again.
