So structured for the vintage, but there’s freshness and vibrancy from the acidity. Full-bodied, extremely creamy and polished. Plush silk. Extremely long, linear and compact. 79% cabernet sauvignon, 11% merlot and 10% cabernet franc.
Barrel Sample: 98-99

99pts Wine Enthusiast

This is an immense wine. Made from 79% Cabernet Sauvignon, it shows great structure, richness and aging potential. The tannins are ripe, showing the gentlest of extraction and are what is going to drive this wine for many years.

I love it when a wine steals up on you, and you very definitely get that here, taking its time on the first attack then rapidly expanding outwards and upwards. Undoubtedly it will knit down as Las Cases can't help itself but do, but there is a creamy almost caramel side hiding among the tannins here. Beautiful power and layers of charcoal, slate, crushed stones, cassis, bilberry and tobacco - all displayed with elegance and tension.

98pts Robert Parker's Wine Advocate

The 2019 Léoville Las Cases is a brilliant young wine that will delight Bordeaux purists. Unwinding in the glass with scents of cassis, dark berries, cigar wrapper and pencil shavings, it’s full-bodied, layered and tightly wound, with a deep core of fruit, lively acids and an abundance of rich, powdery tannins. Concentrated and serious, much like its immediate neighbor Château Latour, it is likely to emerge as one of the vintage’s longest lived—and greatest—wines. Best After 2035

98pts Wine Spectator

Remarkably sleek and pure, considering the generally burly and obvious tannic profile of the vintage. Delivers a pure and unadulterated beam of cassis and plum reduction flavors inlaid seamlessly with a glistening iron girder that seems to have no endpoint through the finish, where violet, anise and black tea notes shimmer. Reserved overall, with a beautiful austerity, this is an example of how great terroir always shines through—even in extreme years. Cabernet Sauvignon, Merlot and Cabernet Franc. Best from 2030.

More backward, deep, and layered, the Grand Vin 2019 Château Léoville Las Cases is 79% Cabernet Sauvignon, 11% Merlot, and the rest Cabernet Franc that saw 90% new French oak. Just awesome aromatics of pure crème de cassis, graphite, tobacco leaf, burning embers, and gravelly earth all soar from the glass. This is followed by a quintessential Léoville Las Cases that's medium to full-bodied, pure, concentrated, and regal on the palate, with beautiful tannins. The purity of fruit is spot on, it's flawlessly balanced, and it’s going to age for decades. While it offers pleasure today, I'd wager it will take 10-15 years to hit maturity and will be a 50+ year wine. Best after 2022. Rating: 97+
