The Rosso Colli Tortonesi comes from all the estate's red grapes that are not directed towards the Barbera Superiore. Several parcels over 3 hectares are harvested for this wine.  The vines were planted between 1955 and 1990.  Exposures are both north and south.  The blend is basically 90% Barbera and 10% Dolcetto, but co-planted throughout the vineyards are small amounts of Croatina, Freisa, Slarina, Brachetto, and unknown grapes, which all make their way into this wine. The bunches are destemmed and fermentation is spontaneous in concrete vats, with macerations lasting 1 month.
