Colli Tortonesi DOC

Colli Tortonesi is the sprawling DOC that encompasses the gentle but characterful hills surrounding Tortona in southeastern Piedmont, in the province of Alessandria. Geographically and stylistically, it occupies a transitional zone between the Langhe to the west, Liguria to the south, and Lombardy to the east—a crossroads position that gives its wines a distinctive personality unlike anything else in Piedmont.

The appellation covers a broad range of wines. Reds are built primarily on Barbera and Croatina, producing wines of lively acidity, dark fruit, and rustic charm. Whites—anchored by the indigenous Timorasso—are where the DOC has earned its reputation for international excellence, particularly in the Timorasso that producers bottle under the name Derthona.

The Terroir
The soils of the Tortona hills are ancient marine sediments—complex layers of calcareous clay, Tortonian marl, and sandy limestone formed when this part of the Po Valley was still submerged. This marine origin gives the wines a characteristic saline minerality, particularly pronounced in the whites. Elevations across the DOC range from the valley floor to steep hillside terraces above 400 meters.

The Style
Colli Tortonesi reds offer a counterpoint to the richer, more tannic styles of the Langhe—lighter in body, higher in acidity, and distinctly food-friendly. The whites, especially Timorasso, have attracted far more critical attention and are discussed separately under Derthona, the historic name of Tortona that producers use for them (an application to recognise it as a denomination of its own is still pending).

Grape Varieties The DOC permits an unusually wide range for Piedmont, which reflects its position on three borders:

• Timorasso: the reason anyone outside Piedmont has heard of the zone, though the serious bottlings now generally carry the Derthona name.
• Barbera: the volume red, and better here than its reputation suggests — the marl gives it a firmer structure than the Asti norm.
• Croatina: locally important, soft and faintly bitter, usually blended with Barbera and occasionally bottled alone.
• Cortese, Favorita and Moscato among the other whites, and Dolcetto and Freisa among the reds.

The Critical Take Colli Tortonesi is best understood as two appellations sharing one name. The white half, driven by Timorasso, has become one of the genuine success stories of Italian wine over the past thirty years and now commands prices to match. The red half remains almost entirely unexamined: honest, well-made Barbera and Croatina sold for a fraction of what comparable Langhe wine fetches, with no marketing behind it and little critical attention. If the zone has an opportunity left, it is there.

At the Table The cooking here borrows from Liguria as much as from Piedmont. The reds suit agnolotti, rabbit, salumi and the local montebore cheese; the whites handle fish, pesto and vegetable dishes, and a structured Timorasso will carry a roast chicken. Serve the reds at 15–16°C.
