Jay - I just got back from a low key vacation in the Loire, and was able to visit Baudry while I was there. We tasted mostly current releases but we also had the chance to taste a bottle of the 2000 Croix Boissee Blanc. It was fantastic - it aged very well and was (at least in those circumstances, straight out of the Baudry cellar) in no danger of imminent decline. Is your 2005 a Croix Boissee Blanc? I forget when they started making the Domaine Blanc as well, but I think it might have been some time after 2005.
So far I have loved '14 chinon…esp. over '15
2000 was the first vintage, IIRC. It was not commercially released, so you were very lucky to taste it. I’ve only had it once.
