LE NOCCIOLE DELLE LANGHE E LA GIANDUJAOf the nearly 7000 hectares of hazelnut in the province of Cuneo, more than a third is in the Langhe, with record highs in cortemiliese, for a total production of about 80,000 tons per year.
The variety present in the territory is the Tonda Gentile delle Langhe (belonging to the species Corylius Avellana), valued for the delicacy of its flavor and also for ease of calibration, excellent peel, good yield to the shelled and detached attitude to the shelf .
In fact, already in the last century confectioners Turin, first of all Prochet Michele, had discovered the organoleptic qualities of hazelnut and had inserted as an essential ingredient in that particular type of chocolate known as gianduja. Since then it has been a crescendo of acclaim and demand for raw materials has pushed farmers in the thirties, to plant the first hazelnut trees of a certain size.
To protect the product, because of the fierce foreign competition, there has been a Ministerial Decree of 2 December 1993 recognized the Protected Geographical Indication under the name of Piedmont hazelnuts intended for the cultivar Tonda Gentile delle Langhe.
The hazelnut spread in a hilly area ranging from 250 to 700 meters and have largely occupied marginal areas, suitable for viticulture.
A Cortemilia and hazelnut Alba gave birth to small and medium industrial laboratories specialized in drying and shelling, plants stretch largely on the hills, almost all of the territory of the Comunità Montana Alta Langa, which since 1975 operates in a Cravanzana ‘experimental farm in collaboration with the Department of Arboreal Cultivation of the University of Turin.
