Molise is a small region with a total area of 4,438 km², and this is reflected in its viticulture and wines as well. It is predominantly a hilly (45%) and mountainous (55%) region, with vineyards located both on hills and in mountainous areas. The total vineyard area is only 6,400 hectares, mostly in the province of Campobasso, producing about 350,000 hectoliters. The vineyards are 58% in mountainous areas and 42% in hilly regions. The plateaus that develop between the Abruzzo and Samnite Apennines give the region a semi-continental climate, with hot summers and cold, snowy winters. Along the coastal strip, temperatures are milder, with modest temperature variations and scarce precipitation. There are two main areas for viticulture: the first, larger area stretches along the valley of the Trigno River (on the border with Abruzzo) and the valley of the Biferno; the second is located inland around Isernia. The traditional Pergola training system is disappearing in favor of the more modern Cordon Spur and Guyot systems.
