I assume you put Cheval Blanc and Yquem above Brane Cantenac but are making the distinction that the Lurtons do not own those two? Does in charge mean that Pierre Lurton works for LVMH?
I was recently at a tasting put on by Panos of Brane Cantenac and did like most of the wines a good bit. Brane Cantenac tasting - WINE TALK - WineBerserkers In fact, I would say over the last 10 years or so I am drinking more and more wines from Margaux appellation that I really like, although I would say that Chateau Margaux (although still outstanding) is probably my least favorite of the first growths.
By the way guys, thanks for the great information.
