Robert Parker's Wine Advocate : The 2013 Cos d'Estournel has a fine bouquet: no vegetal signs here, clean and precise with blackberry, briary and iodine scents. While it does not possess this estate's usual complexity you have to admire the delineation interwoven into this wine.
The palate is medium-bodied with supple tannin, well judged acidity, a gentle grip in the mouth and well integrated oak. There is still some edginess on the grainy finish that will be addressed by another 3-4 years in bottle, but this is certainly one of the better 2013s and it should give 15 years of pleasure.
