The 1990 Don PX Gran Reserva has unusually high sugar, close to 400 grams (when this range is usually less than 360). Compared with the rest of wines, this feels like a very good value. These wines mature in old 550-liter American oak casks for decades, and the wines have great concentration. It felt unusually perfumed, a little spirity and with notes that made me think of Moscatel—notes of orange peel and flowers, and of course the raisin and dry dates and figs from these wines made with raisins. It's sweet and dense like motor oil and leaves a combination of raisins and chocolate in the spicy and faintly warm finish. This was bottled in early 2019.
