Marzeno stretches along the valley of the Senio stream, particularly in the area near its confluence, amongst the foothills of the Faenza-Forlì Apennines. The vineyard-covered landscape follows two ridges running parallel to the stream, at altitudes generally ranging between 100 and 200 metres, with gently rolling contours, interrupted in places by gullies. The soils are predominantly clay-limestone, capable of supporting gradual ripening and imparting structure, depth and a distinct mineral character to the wines. In the flatter areas near Sarna, however, fertile clays come to the surface, associated with wines that are more full-bodied and fruity.
The signature grape variety is Sangiovese, which the production regulations stipulate must be used in an absolute majority, with the possibility of a limited addition of other red grapes authorised for regional cultivation. The sub-zone is dedicated to the Romagna Sangiovese Marzeno and Marzeno Riserva wines, dry reds with a ruby colour tending towards garnet, characterised by intensity, fullness, tannic complexity and ageing potential. The hilly terrain, the balance between clay and limestone, and the valley’s ventilation promote balanced ripening of the grapes. The production regulations require high planting densities, permit ageing in wood and prohibit enrichment, thereby promoting winemaking practices that respect the territory’s identity.
