Well this is quite the find! A gold medal winner at the 2017 Concours International de Lyon and a 2015 vintage claret in the prime of life.
The vintage is important because it's one of the best in Bordeaux in recent times, and by most accounts, along with 2016 it was the finest since the incredible 2010.
It was also a pretty warm vintage, and you can sense this in the still very ripe fruit on the nose, with those classic claret flavours of cassis and leather, with some dried sour cherries displaying its princely development over the last six years.
Then it is soft and medium-bodied, the tannins nicely smoothed out but retaining a bit of bite on the finish, which along with refreshing acidity suggest some life still in this yet. Enjoy it now and for the rest of the coming autumn and winter.
