Casteggio, introduced in August 2010, is one of the very newest DOCs of Lombardy in northern Italy. Based around the town of Casteggio, in Lombardy's south, the DOC focuses exclusively on red wines made from classic north-Italian grape varieties.
Casteggio is not the only commune to be covered by the DOC, although it lies at the center of production. The surrounding villages of Borgo Priolo, Corvino San Quirico, Montebello della Battaglia, Calvignano, Oliva Gessi and Torrazza Costa (all in the Pavia province) also produce the wine.
Naturally, a DOC this young has yet to establish a truly idiosyncratic style for its wines; the first vintage of Casteggio Riserva is due out of oak barrel in 2013.
