The Marenca Cru extends over 2 hectares. It is located in Serralunga d’Alba with south to southwestern exposure in a calcareous-clayish soil. Vines were planted again in 1990 and produce grapes that give a powerful Barolo with typical features.

There are just two cantinas that produce estate-bottled wine from the six-ha Marenca cru: Luigi Pira and Gaja. Pira has the largest holding in this cru with 2.2ha 100% Nebbiolo from 30-year-old vines grown at 350 meters in calcareous clay soils with a south-southwest exposure. Fermentation and maceration on the skins for 7-10 days and the wine is aged for one year in 500-liter tonneaux and one year in 2,500-liter Slavonian oak cask, plus one year in bottle before release.

The wine-making process of Barolo Marenca takes place in horizontal fermentation tanks with temperature control for 12-15 days. The wine matures over 24 months, partly in small wooden barrels and partly in large wooden barrels. Intense garnet red color. The nose is fresh, with complex perfumes that range from wild berries to vanilla, chocolate, and aromatic herbs. On the palate, it is very vigorous, rich in extracts, with lively and pleasant tannins that are rounded through skillful use of wood. A powerful, tantalizing wine with great aging potential.
