"95/100 William Kelley, Wine Advocate
Richer and more demonstrative than the 2016, the 2015 Léoville Las Cases dodders up generous aromas of sweet berries, pencil shavings and loamy soil, framed by a deft application of creamy new oak. Medium to full-bodied, broad and expansive, with a fleshy core of fruit, succulent acids and a giving, gourmand profile, like many 2015s from the Northern Médoc, it's already quite structurally open today, and it will likely attain its peak before both the 2014 and 2016 vintages that bookend it. For many consumers, that may be an advantage. August 2022

The 2015 Léoville-Las Cases has an almost clinical, brilliantly defined bouquet of mineral-rich black fruit, cedar and veins of fresh mint. The palate is medium-bodied with fine-grained tannin, beautifully judged acidity, exquisite balance and tangible energy toward the finish of graphite-infused blackberry and a hint of clove. This is one of the appellation’s most sophisticated offerings in 2015. Chapeau, Jean-Hubert Delon. Tasted blind at the Southwold 2015 Bordeaux tasting. January 2019

A vivid, mesmerizing wine, the 2015 Léoville Las Cases is stunning in its beauty. Unusually rich and sumptuous for Las Cases, the 2015 possesses magnificent intensity and power from start to finish. Blackberry jam, charcoal, smoke, licorice and asphalt are some of the many notes that take shape in the glass, but the 2015 truly stands out for its vertical structure and overall intensity. At the same time, the 2015 is an unusually ripe, exotic Las Cases with much more flesh and voluptuousness in its curves than is the norm. In that sense, the 2015, is not at all typical for Las Cases. And yet it is striking. The 14.5% alcohol is the highest recorded here. April 2016"
