1964 CVNE Imperial Gran Riserva Rioja Alta Tempranillo: a dark red brown colour; a  bouquet of forest mushrooms, earth, soy sauce, and black filter coffee.  On the palate mulberries, blackberries, miso, soy sauce, with a nigh buttery consistency;  with more aeration cassis emanates.  It is not too not thick, a  bit musty, with wood combined with hints of sherry;  rich, smooth, stunning, with a  finish of 60 seconds.  Drink now. 4.25/5
