JFK's favorite! Why can't they be replaced?
His favorite was the Petit Upmann, which was similar in size, but supposedly a slightly different blend - I believe the Petit Corona was the high end mareva in the Upmann line with the PU being a step below, but above the Epicure, Majestic, and Coronas Major and Minor.
They were sadly discontinued in late 2016. I always kept a couple boxes on hand, but when that was announced, I hoovered up all the boxes I had room for - 8 boxes in total when they left the market. I continued to smoke through them, hoping it was a fluke, or perhaps a discontinuation a la Sancho Panza Non Plus, which is STILL listed as discontinued in the HSA catalog, but is still being produced. Unfortunately, the last boxes anyone saw were dated January '17. I have a couple of those and they were exemplary in terms of construction and wrapper quality. As a matter of fact, the final production was some of the best Upmann PC I had ever seen.
I've got 2 full boxes plus this recently-opened one left. I smoke through them as a special occasion smoke, which is unfortunate because I used to smoke 1-2 of these every week. With the new pricing and availability issues that have hit Havana cigars, it's a moot point now anyway, as I probably wouldn't be willing to pay the asking price.
