Robert Parker's Wine Advocate (RP): 94
"...the 1990 Cos has reached full maturity. It exhibits sweet berry fruit intermixed with spice box, herbs, and spring flowers. Expansive, round, and sensual, with wonderful purity as well as lushness, this irresistible wine can be enjoyed over the next 6-10 years."
Stephen Tanzer (ST): 92+
"Good full medium ruby. Perfumed aromas of cassis, redcurrant, plum, minerals, coconut and violet. Lush, dense and gentle; rich and chocolatey... But finishes tight, with a touch of austerity and nicely restrained sweetness. Still quite young. Drink 2005 through 2020.
