Interesting suggestions, and I thank you all.
No, Germany is not an option. My older daughter doesn't care for Riesling at all, nor Gewurztraminer. My younger daughter adores them, but she hasn't married yet, nor even started dating seriously.
The Cour d'Argent is around $10, and I don't suppose it will last until their argent anniversary. Too bad. Better wines incur higher prices, of course. There is also a higher risk of getting a bad one. Well, not actually, but there is a much better chance of having a good one if I have 12 than if I have 2, or even 1. If that one is bad, there is no recourse. If 1, 2, or 6 of the less expensive ones are bad, I can simply open another one.
The lesser houses of Margaux are certainly an option. Brane-Cantenac has been mentioned, and I've had a Cantenac-Brown I liked in the past. Another thought I haven't investigated (and no one has mentioned, which surprises me a bit) is Italy. Maybe a Barolo would be the ticket.
No, I don't suppose I have to buy now, but I don't expect to be in any better position any time soon, and, if prices continue to go up, now might be better than later. My net income has, in fact, been trending downward over the past several years, when corrected for inflation.
