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.

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 end point 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 through 2050. — JM

The 2019 Léoville–Las Cases, bottled July 2021, retains the energetic, vivacious bouquet that I noticed last year from the barrel sample, offering intense blackberry, bilberry and still those faint shucked oyster shell scents in the background. The palate is medium-bodied with wonderful detail and precision, a mixture of black and blue fruit and enthralling clarity and length. Perhaps there is a little more creaminess in terms of texture toward the finish, a bit of "baby fat" that will be subsumed with time, so give this 8–10 years in bottle if you want to taste it in full flight. [Returning after 15 or 20 minutes, I discerned more pepperiness on the finish, and perhaps also less creaminess and more structure.] 14.02% alcohol.
