85% Nerello Mascalese/15% other. Acosta organically 3.5 hectares on the north face or versante nord of Mt. Etna. The parcels are scattered amongst 6 different contrade or districts (currently Pietramarina, Allegracore, Sciaranuova, Friera, Santo Spirito and Marchesa). Averaging over 50 years old, the vines are in alberello, either as individual bushes or on wires depending on the parcel; the varieties are interplanted and include a preponderance of Nerello Mascalese and Nerello Cappuccio, as well as smatterings of Alicante, Garnacha and other reds (plus many white varieties). The soils are sandy volcanic ash and the elevation ranges from 550 to 850 meters.

The bunches are hand-harvested, vinified as a mix of whole clusters and destemmed berries, co-fermented spontaneously with native yeasts and without sulfur or temperature control in concrete tank. Maceration lasts around 15 days. The wine is aged for 16 months in concrete tank with minimal racking. It is bottled without fining or filtration and with a tiny amount of sulfur. Versante Nord Rosso is the largest bottling from Acosta's overall very small production.
