In documents from 1600 there already are some references to Cortese vineyards. Demaria and Leardi confirmed the presence and prosperity of Cortese in the province of Alessandria, from Ovada to the Tortona hills, and in particular in the area of Gavi, where even today it achieves the highest quality levels.
Only in 1974, the “Gavi” or “Cortese di Gavi” wine, produced with cortese grapes, will become a D.O.C. wine, in Italian “Denominazione di Origine Controllata”.
In 1998 it became a D.O.C.G. wine.
