This is the principal Barolo of the estate, at least in terms of quantity produced. The vineyard is the Gabutti cru and the exposure is south to southwest. After an extended fermentation and considerable aging in the classic botte of the region, the wine is bottled without filtration. The rhythm of the release is usually four to four and one-half years after the harvest. Stylistically, the wine is an honest and pure reflection of the terroir of this small but important cru: earthy, truffled aromas marry to a full-bodied, occasionally rustic character backed by rugged, classic tannins. The Barolos of Serralunga are known for their generosity and warmth and the Rupestris is as fine an example as one can find.
