Ca' Bianca is a Piemontese wine estate in Castelletto Molina (Monferrato, Asti province), producing from the Monferrato hills in the southern Piedmont the zone associated with Barbera d'Asti, Moscato d'Asti, and the sweet sparkling Asti Spumante DOCG. The estate focuses on Piemonte's most accessible DOC varieties: Barbera d'Asti (the everyday red of Piedmont, high acid, low tannin, fruit-forward), Gavi DOCG (Cortese white from the Gavi zone), and Moscato d'Asti (low-alcohol, slightly sweet, lightly sparkling).

For programmes wanting to build an Italian wine selection that includes accessible, food-friendly Piemontese styles beyond Barolo and Barbaresco, Ca' Bianca provides the Monferrato entry tier: Barbera d'Asti as the by-the-glass everyday Piemontese red (high-acid, medium-bodied, reliable), and Moscato d'Asti as the low-intervention sweet fizz for dessert pairing or aperitif service. The estate's position in the Asti zone rather than the Langhe gives the range a distinct character from the more structured Nebbiolo-based productions.
