Together with younger brother Tino, daughter Federica and nephew Pietro, they established Poderi Colla (literally, the Colla farms), made up of three estates:
Cascine Drago in Alba, heart of the Langhe appellation
Tenuta Roncaglia, eight hectares of the historic Barbaresco cru
Tenuta Dardi Le Rose, seven hectares of the renowned Barolo Bussia cru in Monforte

Federica’s words perfectly summarise the Colla philosophy: “Our wines are not ‘high-tech’. They are man-made, with a strong human element, outstanding natural concentration thanks to terroir and fruit and very well balanced components”.
