Particle4 told you it's possible to find better wines than those or to discover new wines and I'm sure he is right.
But for all wines we have tasted, there is more than a technical description of color, flavor or taste. The affective context you lived at this moment, the place where you were and friends around you were participating to this special feeling you want to live again...So I understand that you want to try those wines again.
