The reason I was told back in the 1970s is that one buys two cases so that one can be drunk and the other sold to get two cases of the then current (or en primeur) vintage.
I bought a case of the 2014 Caro. It is one of the best wines I have ever bought in terms of bang for your buck. I think it was about £30 per bottle when I bought it but drinks as well as anything from Bordeaux at two or three times the price.
I saw it on a wine list recently in a restaurant at £120.
might have worked in the 70s…not so much now
guess, just have to drink two cases worth
It’s amazing how quickly you can get through 2 cases if it is a wine you like and you are not the only wine drinker in the house .
I am talking about many months, or a few years, but not many wines I buy are going to fade away in that timescale, and most will improve.
The important thing is to make sure you really do like it first, and that it works with food styles you regularly eat.
