It is impressively fascinating to walk around the nine hectares of Tosca vineyards, perfectly located on the Valcalepio terraces, and cultivated following the organic viticulture. The very typical soil structure is given by the so-called flysch, a mix of limestone and clay rock which gives to our wines their characteristic minerality and sapidity.

The particularly favourable microclimate of this hilly region, permit to contain the agronomic issues. Since a long time the company was oriented toward the organic cultivation, always limiting plant protection to small amount of copper and sulphur to fight against the main pathogens. 

The most cultivated varieties are Merlot, Cabernet sauvignon, Chardonnay, Pinot gris, Franconia, Incrocio Manzoni e Riesling. As soon as these grapes are perfectly ripened they come to the new cellar and are transformed in the DOC wines called Doc Valcalepio and Doc Terre del Colleoni, which are coupled to the IGT Bergamasca.
