I was at the chateau earlier this year and tried the 2005. After tasting, I bought as many bottles as my suitcase would hold.
I was disappointed. I was at the Chateau in March of 2010 and sampled the 2006. They are one of the largest producers in the Medoc region (similar to KJ). I feel like they do not go for finesse which is a major characteristic of this region. It was too alcoholy and made it difficult to taste the notes. I would suggest cellaring or passing for another wine in this epic production region. If you are searching for a great wine from this region, seek out the 2006 Chateau Dauzac (not the La Bastide Dauzac). Great and full bodied, well balanced with notes of cocoa and leather. Delicious and incredibly close to the terroir of Chateau Margaux. Also, quite cheaper.
