The 2021 Clos du Marquis is a lovely wine, offering up aromas of cherries, burning embers, dark berries, loamy soil and truffle, followed by a medium to full-bodied, layered and velvety wine that's rather deep and serious, reflecting low yields of 30 hectoliters per hectare and a blend dominated by 67% Cabernet Sauvignon, with 19% Merlot and 14% Cabernet Franc in supporting roles. Lest anyone underestimate it on the strength of the challenging vintage alone, by the numbers it contains a higher concentration of polyphenols than either the 2019 or 2020 vintages. Tasted three times.
