I absolutely loved the 2015 Léoville Barton and this has everything you could want from a Left Bank Bordeaux. Cassis, smoked earth, graphite, tobacco leaf, and thrilling amounts of minerality all emerge from this inky colored, full-bodied, power-packed, brut of a Saint-Julien that holds everything together and stays pure, balanced and elegant on the palate. It has a lot of tannins, yet more than enough fruit. The 2015 is a blend of 86% Cabernet Sauvignon and 14% Merlot, brought up in 60% new French oak, and it needs 7-8 years of bottle age and will shine for 2-3 decades. Bravo!

The 2015 Léoville-Barton is superb. Vivid and wonderfully nuanced in the glass, the 2015 offers exceptional purity in its aromas and flavors. As always, the house style favors finesse over pure power, but in 2015 there is a good bit of both. Graphite, pencil shavings and crème de cassis, herbs and mocha meld into a rich, textured, beautifully persistent finish. The tannins are there, but they are nearly buried. Léoville-Barton is not the most powerful or showy Saint-Julien in 2015, but it is class personified. Don't miss it. Tasted two times.

The 2015 Leoville Barton has a medium to deep garnet color. It is a little shut down and reluctant to play, eventually offering scents of baked blackberries, blackcurrant cordial, and cedar chest, followed by hints of crushed rocks and smoked meats. The medium-bodied palate is tightly wound with bright, energetic fruit and compelling freshness, supported by ripe, grainy tannins, finishing long and lifted.

This is a very focused Barton with ultra-fine tannins that are so polished and chalky. It drives through the center palate with currant and berry character. Full-bodied, polished and straightforward with driving tannin. Love the texture. Class. Yes. Drink in 2021.
