I identify with this, too, but it presupposes that the other party knows something about what it is that they are drinking or has a particular interest in the bottle.
Case in point I had my best friend and his family over a couple weekends ago. They have been to Napa several times and enjoy richer pinots and cabs. The first night, we went to dinner and had a 1985 (his birth year) PLL that I had double decanted beforehand which was absolutely beautiful, showing better than I expected. It was enjoyed, worked with the food, and we had a lovely night.
The following night, we went to a different restaurant, where I ordered a 15 Bereche Rilly la Montagne and a 17 Dauvissat Forest. I thought the Dauvissat in particular was fabulous, but the group was more engaged and attention never really turned to the wine. Later, the somm who I know brought two blind glasses for me - a 17 Huet Haut Lieu demi sec and an 18 Château Lassègue (right bank bdx). The wine gods were in my favor and I called them both correctly, including the producer in the case of Huet.
The last night, we had steaks at home and I opened an 18 Maybach Materium that we just enjoyed from the bottle.
When I later asked what his favorite wines from the weekend were, the reply was, “the ones you guessed right at the restaurant. Just kidding, it was that great cab from Napa, 100% where can I get some of that? Oh, and what was the older one we had with dinner the first night?”
I don’t regret any of it, we had a blast, but I’ll probably save the handful of now rarities (Vatan, Juge, Raveneau, etc) in my cellar at least for interested parties. On that note, a person in one of my tasting groups mentioned never having had Raveneau before so we opened one last summer. That was the perfect setting for me - to satisfy someone.
