One more single-harvest, old sweet wine, the 1955 Don PX Convento Selección was bottled in September 2014 and it had been aged slowly in very old American oak barrels and getting thick and concentrated through evaporation. It's 320 grams of sugar are (partially) compensated by 6.5 grams of acidity. It has a nose and palate of chocolate-covered candied orange, spices, molasses. I'd say the dominant aromas in the nose are dark chocolate. It's very dense, developing notes of very concentrated licorice and balsamic, mint, camphor and evolving notes of petrol with time. Complex, rare and unique. 8,400 bottles.
