The identification of the Crus begins with the study of the ancient maps of the Langhe district, a patient search through the archives, driven by the desire to become better acquainted with one’s territory while at the same time wishing to elevate its value in terms of uniqueness of production.
In due course, the map realized by Renato Ratti in 1971 becomes a part of the territory’s culture, and not only regarding wine. And in any case, still today, it is used to identify the best suited areas and as of 2010 it is officially used to identify the MGAs (special mention areas) of Barolo.
