The tannic, full-bodied 2018 Hermitage Les Dionnieres boasts ebullient aromas of blueberries and boysenberries, leavened by hints of peppery herbs, black tea and star anise. Expansive on the palate but structured and dusty, with a lingering finish of salted licorice and blackberry pastilles, it ideally needs a few years to settle down, but it should then drink well for more than a decade.
