Colli Tortonesi

Characteristic

Terroir

The Tortonesi Hills extend across 46 municipalities in the province of Alessandria, in a hilly belt that connects Piedmont, Liguria, Lombardy, and Emilia. A borderland and meeting point, characterized by harmonious landscapes and a long agricultural tradition. Viticulture here has ancient roots, favored by a mosaic of marine soils and climatic conditions that alternate between the Po Valley and the Apennines. Among these soils, the famous Sant’Agata Fossili Marl stands out, deposits dating back to the Miocene, considered among the most suitable formations in Italy: rich in limestone and clay, they give the wines minerality, structure, and longevity. Alongside these, other marly and sandy soils contribute to a range of expressions that make the Tortona Hills a complex and fascinating territory.

Clime

The climate in the Tortona Hills is temperate and humid, with hot summers and cold winters. Summers are generally hot and muggy, while winters are characterized by low temperatures and cloudy periods. Annual precipitation ranges between 800 and 1100 mm.

Grapes

This geological richness is reflected in the diversity of the cultivated grape varieties: Timorasso, reborn as Derthona, which has brought Tortona back to the center of the international winemaking scene; Barbera, which finds its deepest and most enduring expression in the Monleale subzone; Cortese, Dolcetto, Croatina, and other local varieties that complete a valuable ampelographic heritage.
