Because the 2005 Mouton is way too young, it is the CDP or burg for me. I much prefer burgundy over CDP. great vintage and top maker, so the Mugneret-Gibourg NSG Vignes Rondes 2002 should be ready to go.
2005 Ch Rayas
I would think that the 2005 Lafleur is almoast certainly way too young. The 2005 Rayas is stunning and a world class bottle of wine. The 2005 MG Clos Vougeot probably also needs more time
For me, 1C and 2A. I’ve had 2000 Pegau Capo and don’t love it (I think the Reservée is better), the Mouton is too young, and I’ve had the M-G and it is incredible. For the options under 2, I’ve never had a Lafleur, though the 2005 Rayas is amazing.
As others have noted, Mouton may be too young and the Rayas should be more interesting alongside M-G, plus it makes for a more versatile dinner pairing.
