Valiano 6.38 Chianti Classico Gran Selezione is a premium DOCG red wine from the Castelnuovo Berardenga zone of Tuscany, Italy. The name "6.38" refers to the precise vineyard parcel — 6.38 hectares (approximately 15 acres) — situated at roughly 1,100 feet above sea level within the renowned Chianti Classico appellation. The estate Valiano is a historic Tuscan property deeply associated with Sangiovese-based wines.

The wine is composed primarily of Sangiovese (approximately 90%), with small portions of Cabernet Sauvignon and Merlot rounding out the blend. It presents a deep ruby color with aromas of blackberry, black currant, plum, wild sage, and mocha. On the palate it is elegantly structured with fine-grained tannins, notes of prune, cassis, and dark chocolate, and a long finish. Gran Selezione is the highest tier of the Chianti Classico designation, reserved for single-vineyard or top-selection wines aged a minimum of 30 months. This bottling has earned critical acclaim including 94-point scores and is considered an outstanding value within its tier.
