Casteggio DOC

One of four denominations carved out of the Oltrepò Pavese in 2010 to give historic styles their own names. Casteggio covers a structured, oak-aged red from the hills around the town of the same name, and it is the most serious of the group.

The Terroir The registered file places the zone within the wider Oltrepò: hill country with a dry winter climate, ventilated in summer, and large temperature swings, which it says make the area suited to growing grapes and making wine. Training systems, planting densities and pruning are the traditional ones, and the file notes that the production yields are what give the wine its particular complexity. The Oltrepò is the Lombard side of the Apennine foothills, geologically continuous with the Piedmontese Monferrato across the border.

Grape Varieties Croatina and Barbera form the base, with Uva Rara and Vespolina permitted alongside — the classic Oltrepò red blend. Croatina supplies colour, soft tannin and a faintly bitter finish; Barbera supplies the acidity it lacks. Casteggio requires extended ageing including a period in wood, which separates it from the everyday reds of the same grapes.

The Critical Take The Oltrepò Pavese is the great underachiever of Italian wine — one of the largest quality zones in the country, historically the main source of Pinot Nero in Italy, and almost entirely unknown because most of its fruit has always left in bulk for sparkling production elsewhere. The 2010 restructuring, which created Casteggio alongside Buttafuoco, Sangue di Giuda and Bonarda, was an attempt to give the better wines names that could not be confused with that bulk trade. Whether it has worked is still an open question, but Casteggio is where the zone’s ambition for still red wine now sits.

The 2010 Restructuring Four denominations were separated out of the Oltrepò Pavese DOC in 2010 — Casteggio, Buttafuoco, Sangue di Giuda and Bonarda — each having previously been a named style within it. The logic was that a wine identified only as “Oltrepò Pavese” told a buyer nothing, since the same words covered bulk Pinot Nero destined for sparkling production elsewhere. Whether four small unknown names solve a recognition problem better than one large unknown name is a fair question, and the zone is still answering it.

At the Table Lombard and Pavese cooking: risotto, braised beef, salame di Varzi, roast goose, and aged Grana. The structure and the wood ask for meat rather than pasta. Serve at 17–18°C and decant a young bottle.
