Unwinding in the glass with notes of cassis, wild plums and red berries that are complemented by nuances of peonies, heather and dark chocolate, Dujac's 2017 Bonnes-Mares Grand Cru is full-bodied, deep and incisive, its tight-knit core structured around fine but chalky tannins and tangy acids. Firm and introverted, as is so often the case, it has superb potential and will reward the patient, but readers considering purchasing this serious Bonnes-Mares should count on exercising over a decade's patience before opening bottles.
