Deep ruby with a violet rim. The nose opens on red currant and black raspberry, then turns savory: roasted red pepper, tobacco leaf, dried sage, and a graphite edge that reads pure high-altitude Cabernet Franc rather than a Malbec stand-in. The palate is full-bodied but tightly wound — alluvial-soil tension, fine-grained tannin polished by 15 months in French oak, and a mineral, faintly herbal finish that keeps the fruit honest.

The story here is the site. Corazon del Sol sits in Los Chacayes, the Uco Valley subzone the estate helped put on the map, with vines planted at over 3,800 feet on deep alluvial rock and sand eroded off the Andes. That altitude is what separates this from Loire or Right Bank Franc: brutal solar intensity ripens the fruit fully while cold mountain nights lock in acidity, so you get the variety's pepper-and-tobacco character without a trace of green. The project belongs to Dr. Madaiah Revana of Napa's Revana Family Vineyard, with winemaking shaped by Santiago Achával — the co-founder of Achával-Ferrer, the producer that arguably defined modern single-vineyard winemaking in Mendoza. The estate's own winemaking team considers Cabernet Franc the variety that has evolved best on this site after Malbec, and this bottling is their argument for why Argentina's next chapter may not be Malbec at all.
