Which one to open tomorrow night?

Lafon Rochet
Sociando Mallet
Lagrange
d'Armailhac
Pontensac

I think you'll enjoy the Pontesac.

The Lafon Rochet will not improve. The 96 is young...the 95 is just not as good, and not going anywhere but sideways or down. I'd decant and go for it.

The only one I've had of these is the Sociando, and I think it's a terrific wine that hasn't peaked yet. Most 95s are probably just starting to come into their own, but in my experience they can all use some air.
