96 - 98+ points. "This is the most backward and unevolved of all the Left Bank (Medoc) first-growths. In 10-20 years, the 2009 Mouton Rothschild should rank alongside the greatest vintages of the last three decades (1986 and 1982). Yields were a small 30 hectoliters per hectare, the final blend is 88% Cabernet Sauvignon and 12% Merlot, and the finished alcohol is 13.2% (not particularly high in this vintage). The pH is 3.81, and the index of tannins, the highest ever measured, a whopping 20% higher than the next highest vintage. The tannins, while present, are silky and well-integrated, one of the hallmarks of the 2009 vintage. An inky/purple color is accompanied by classic aromas of creme de cassis, violets, and hints of graphite and background oak. The overwhelming impression is one of layer upon layer of fruit, full-bodied opulence, and good structure. It tastes as if it were 2-3 months old rather than a post-malolactic, fully assembled barrel sample ... it’s that young, but so incredibly promising. A 50- to 100-year wine? Probably"
18.5 points. "Very dark indeed. Very Mouton. Very exotic, minerals, spice and old ladies' handbags. Lovely topnotes. Real excitement on the nose here. Obviously great density but lots of grace notes. Lovely palate entry and glossy texture. Then again drier and a little more astringent than its peers on the finish. A difficult wine to mark because the nose is SO gorgeous! I think it may require just a bit more patience than some. Just seemed in a slightly low register when I tasted it. All the Mouton wines had ruder tannins than usual in 2009."
