Renato Ratti was one of the most influential and important figures in the modern history of Barolo. Before his untimely death in the 1980s he had created his own brilliant estate in the frazione of Annunziata (La Morra), been a strong advocate for a modern style winemaking, served a term setting policy for the area and set the wheels in motion to convert the Barolo castle into a museum honouring the production of its most famous export.

These days his son Pietro and long-time winemaker Massimo Martinelli continue to turn out exemplary wines all hung off more modern styling. The most significant of the wines is his top Barolo Marcenasco but the wines across the range are superb. In style they all share a plushness and suppleness that plays well with the La Morra terroir.
