By law and tradition, Gorgonzola cheese production is allowed in only two Italian regions and only the following provinces: Novara, Vercelli, Cuneo, Biella, Verbano Cusio Ossola, and the area of Casale Monferrato for Piedmont region, and Bergamo, Brescia, Como, Cremona, Lecco, Lodi, Milano, Monza, Pavia, and Varese for Lombardy region.
Only milk produced in such provinces may be used to produce and grant Gorgonzola cheese a DPO certification, ensuring its authenticity from raw material.
Gorgonzola cheese is now produced by approximately 30 cheese factories in modern plants processing milk in accordance with hygiene and health standards, with fully equipped laboratories and the care and experience required for a kind of cheese that requires significant manual work and inspections.
Approximately 3,000 farms in the Consortium territory provide the milk used for Gorgonzola cheese production. At present, total production is above 4 million rounds per year, i.e. 48,000 tons total. The retail turnover is above 500 million Euros.
