Robert Parker's Wine Advocate : The 2012 Château Margaux is showing much differently from bottle than it did from cask. Seemingly much fuller and richer, it has a dense ruby/purple color, representing a blend of 87% Cabernet Sauvignon and the rest mostly Merlot, as well as only 33% of their harvest. It possesses hints of spring flowers intermixed with blueberries, blackberries and cassis fruit, moderate tannin, a multi-dimensional mouthfeel, and a long, structured finish.
This 2012 was charming, up-front and precociously styled from barrel, but in bottle it is more masculine, dense and rich. This wine needs a good 5-7 years of cellaring, and should keep well for 25 or more years. This is a great effort from Château Margaux, and should handsomely repay those who buy it. Anticipated maturity: 2023-2040.
Blend : 87% Cabernet Sauvignon, 10% Merlot, 2% cabernet Franc and 1% Petit Verdot.
