Rocche Costamagna is a historic company. On 15 May 1841, the Police Office of the Royal Military Command of the city and province of Alba granted Luigi Costamagna, son of Francesco Antonio, permission "to sell wine at retail [...] for the wine produced from the grapes of his vineyards" in La Morra. When Francesco died, his son Riccardo, a lawyer in Turin and Alba, continued to run the business with the help of his wife Maddalena. In the 1930s, after Riccardo's death, Maddalena sold the vineyards outside La Morra, but not those located in the Rocche dell'Annunziata. At the end of the 1960s, her granddaughter Claudia Ferraresi, together with her husband Giorgio Locatelli, decided to take over the reins of the family business, combining her profession as a painter with that of wine entrepreneur. Claudia Ferraresi conceived many important initiatives for the Langhe: in 1975 she created the "Ca dj'Amis", a cultural association which suggested an interpretation of Piedmont seen from different aspects: from local art to micro-history, from minorities to the food and wine culture of the Langa and the recovery of excellence as a tourist and cultural resource. It organises "Le tavole della cultura", around which events and initiatives on food and wine are organised through conferences, books and essays. Among others, the series directed by Claudia Ferraresi "Cibo di carta" and "Libri da gustare", an annual selection of twenty food and wine titles. In 1990 he founded "I Ristoranti della Tavolozza", a select group of hospitality professionals committed to food education with initiatives aimed at the public, schools and gourmet enthusiasts.
