Robert Parker's WINE ADVOCATE Rating & Tasting notes:
92+ Points
The 2003 JJ Jacinto Jaure Gran Reserva is a blend of Malbec (40%), Cabernet Sauvignon (30%), and Syrah (30%).  The fruit was sourced from a 53 year old vineyard and aged for 18 months in a new French oak before being bottled unfiltered.  Purple in color, it has a fragrant bouquet of pain grillé, Asian spices, pencil lead, black cherry, blueberry, and black currant.  Ripe and sweet on the palate, it has plenty of silky tannin well-concealed under a blanket of fruit.  Nicely balanced and lengthy, it will evolve for 6-8 years and drink well through 2025.
 

Bright and intense purplish-red color.  Its aroma combines ripe red fruits, such as cassis, plums, and blackberries; together with vanilla, chocolate, and leather.  It possesses great structure, round and perfectly well balanced.

Spices and earthly aromas are present, and tannins are firm.  Perfectly balanced acidity.

Superb structure, lavish mouthful of enriched fruits, plush and spicy. 
Aged in oak barrels, it is a harmonious wine with a long and complex finish.
