As difficult as it is to pick a winner between the Gualtallary and El Cepillo bottlings, the 2021 Gran Enemigo Gualtallary Single Vineyard gets my nod as the supreme example of the Gran Enemigo Single Vineyard Cabernet Francs. It hails from a plot planted on calcareous rocky soils in 1995 with 10,000 vines per hectare, fermented with 40% whole bunches in barrique and underwent a 15-month élevage in 100-year-old foudre. Opening with a brooding, inward and quietly perfumed nose, its aromatic profile ceaselessly expands to encompass all manner of herbal and floral complexity, combining simmering intensity with supreme elegance. The palate follows suit with a rich, silky, refined and gently succulent energy, releasing into a graceful, dense and glacial conclusion that gives equal measure to vertical energy and horizontal richness. The finish slowly but steadily builds upon itself, revealing shimmering acidity and ultra-refined tannins with increased aeration. There is no better example of Cabernet Franc's suitability in the Uco Valley, a match rendered here with incomparable finesse, depth and complexity. Drink date: 2024-2041. Score - 99.

The 2021 Cabernet Franc Gran Enemigo Los Chacayes Single Vineyard is quite simply a 'wow' wine that nearly defies description. The incredible perfume of violet and white pepper invites one in first, followed by crisp, complex layers of cassis and currant. Then there's tension and a punch of acidity, adding length, grace, and structure. It's the aging potential of another 20-30 years that ultimately puts a halo over it all that speaks most forcefully to the greatness of this wine. Maturity: 2025-2055. Score - 100.

Aromas of black licorice, iodine and blackberries with hints of nutmeg. Medium- to full-bodied with a super structure yet at the same time polish and finesse. Extremely long and attractive with energy and polish. The glacial soil and western aspect of the vineyard make this special. Better in two or three years and beyond. Try after 2027. Ranked #39 in James Suckling's Top 100 World Wines of 2024. Score - 99. (jamessuckling.com, Feb. 4, 2024)

Salty and spicy, with aromas of ginger, cardamom, lemons and sea salt. The palate is medium- to full-bodied, sharp and pungent, with a precise, saline character. Rich, focused and delicious. From grapes grown in Gualtallary. Fermented and aged in French oak, of which 35% was new. Drink or hold [through 2029+]. Score - 96. (Jacobo Garcia-Andrade Llamas, jamessuckling.com, April 15, 2025)

Agrelo reds generally tend to be generous in sweetness - friendly wines that go very well with roast meat. There is some of that in this cabernet franc with 15% malbec and aged in foudres that are more than 100 years old. It has that succulent sweetness, the aromas and flavors of black fruits, but it also has the hand of the winemaker, Alejandro Vigil, who gives Agrelo a turn of the screw and makes it more piercing and extreme. Leave it in the glass for a while, and you will see how the tart red fruits and herbs appear in a wine that is at the top, among the best in the area. Score - 96.
