Renato Ratti came to wine without any family tradition. Free from ancestral ties, he was able to live Barolo without any kind of conditioning. In 1965 Renato Ratti buys the first vineyard for the production of Barolo: it is a small vineyard in the historical area of Marcenasco, under the Abbey of Annunziata in La Morra. In the ancient Abbey (XV century) is vinified the first Barolo Marcenasco, coming from a single vineyard (cru). In 1969 his nephew Massimo Martinelli, also an enologist, joined the winery and with him was developed the vinification, maturation and refining technique of Barolo Marcenasco, in order to obtain a refined elegance, finesse and longevity of this important wine. From the mid-seventies to the end of the eighties Renato Ratti becomes an important point of reference for the wine of the Langhe and Italy. He is appointed president of the Barolo Consortium and then director of the Asti Consortium. After his untimely death, his son Pietro, who had just graduated from the School of Enology of Alba, joined the company. In the '90s he continued the enlargement and the restructuring of the family vineyards and continued the search for the uniqueness of origin of the various subzones.
