Renato Ratti is born in 1934. After studying enology in Alba he "emigrates" to Brazil where he is put in charge of the production of Vermouths and sparkling wines for Cinzano of Sao Paolo. The experiences gained operating in such a vast, and challenging country as Brazil will prove fundamental in the development of an innovative outlook, one that will characterize his later work back in the hills of Piedmont's Langhe region.

In 2002, construction of the new Annunziata cellars begins, cellars structured in a manner to guarantee the continuation of that mission of vinification and refinement started by Renato Ratti in 1965, that of maintaining with single-minded purpose the utmost respect for the grapes and vineyards of origin.
