Deep garnet-purple in color, the 2018 Léoville Barton needs a little swirling to coax out delicate notions of fresh blackberries, mulberries and cassis, plus touches of pencil shavings, clove oil, charcoal and black truffles. The medium to full-bodied palate delivers a great intensity of earth and mineral-laced black fruit flavors, supported by firm, ripe, grainy tannins and seamless freshness, finishing on a lingering ferrous note. Give it a good 4-5 years in bottle and drink it over the next 20 years+.
