Made from 81% Cabernet Sauvignon, 11% Cabernet Franc, and 8% Merlot, the 2020 Leoville Las Cases is deep garnet-purple in color. After a swirl or two, it erupts from the glass with explosive scents of blackcurrant cordial, stewed blackberries, juicy blackberries, and violets, leading to suggestions of licorice, cinnamon toast, and fertile loam with a touch of truffles. The medium-bodied palate is tightly wound with loads of nuanced black fruit, earthy, and floral layers, supported by very fine-grained tannins and seamless freshness, finishing long and multi-layered.

This is incredibly classic in style with so much currant, lead pencil, crushed stone and sweet tobacco. It’s full-bodied with minerally, stoney and powerful tannins. It goes on and one. Real Las Cases here. Solid as a rock. Progresses to violet, graphite and licorice at the end.

The 2020 Léoville Las Cases has developed into a powerhouse. Then again, that is Las Cases. En primeur, I thought the 2020 was a bit shy, but its true personality has to emerge. Blackberry jam, gravel, spice, menthol, licorice, espresso and plum all saturate the palate. Vivid and explosive, the 2020 is dizzyingly rich, with plenty of Las Cases tannins that will require patience. I am not sure when the 2020 will be ready to drink, but it won't be anytime soon. Las Cases is one of the wines of the vintage in 2020, that much is pretty clear.

The 2020 Léoville Las Cases is a blend of 81% Cabernet Sauvignon, 11% Cabernet Franc and 8% Merlot, aging in 80% new French oak barriques, weighing in with an alcohol of 13.68%, a pH of 3.8 and an IPT (tannins index) of 79. The Cabernet Sauvignon was harvested from the 21st to the 27th of September, the Merlot from the 12th to the 15th of September and the Cabernet Franc on the 18th and 19th of September. With an opaque purple-black color, it slowly unfurls to reveal beguiling notes of fresh blackcurrants, Morello cherries, candied violets and dark chocolate, giving way to an undercurrent of crushed rocks, unsmoked cigars, clove oil and fragrant earth. The medium-bodied palate is a powerhouse of energy, delivering tightly wound red and black fruits, mineral and floral layers, supported by fantastic tension and incredibly ripe, silt-like tannins. The finish has jaw-dropping fragrance and depth.

The flagship 2020 Château Léoville Las Cases checks in as 81% Cabernet Sauvignon, 11% Cabernet Franc, and 8% Merlot, raised in 80% new French oak. Hitting 13.68% in alcohol with a Ph of 3.8 and an IPT of 79, it shows the dense, concentrated, focused style of the vintage and it's going to be one of the longer-lived wines of the vintage. Deep purple-hued, with an incredible sense of minerality in its blackcurrant and black cherry fruits, it's full-bodied, has a rich, layered mid-palate, lots of tannins, and a great finish. It's a beautiful wine and holds onto the more inward, concentrated style of the vintage while still showing serious depth of fruit. It's going to take a decade (or more) of bottle age to get anywhere close to the early stages of maturity but will keep for 30-40 years.

The wine's richness comes both from the dark tannins and the pure, classic black currant flavors. Acidity, yes, but surrounded by dense fruits and tannins that give the wine considerable structure and the potential to age for many years. An impressive wine.
