The 2015 d'Issan is a total knock-out. Spectacularly ripe and intense, the 2015 exudes richness in all of its dimensions. Super-ripe dark plum, lavender, spice, savory herbs, iron, smoke and new leather add myriad shades of nuance to this super-ripe, decidedly hedonistic Margaux. A powerful, dense wine, the 2015 is going to need a number of years before it is close to being ready to drink. I was quite impressed with d'Issan both times I tasted it. The 2015 has really come along nicely. The blend is 65% Cabernet Sauvignon and 35% Merlot, aged in 50% new oak. Eric Boissenot consults.
