One of my favorites was a 1959 La Tour, as I was fortunate enough to have it with a 1970 La Tour and a 1976 La Tache DRC Monopole with Board-O down in Florida.
another was a 1982 chateau Margaux. consumed at a very good restaurant in Baltimore, The Prime Rib
these were great experiences.
Sometimes the situation enhances the wine In 2017 I had a 2003 Pesquera gran reserva Janus at Akalere in San Sebastián, Spain. It was shockingly inexpensive. The sommelier said it was his last bottle of the 2003. Of course, the food and the environment were both superb.
