How Italian Gorgonzola Cheese Is Made | Regional Eats | Food videos

The Gorgonzola industry is worth over $800 million. Almost 5 million wheels are produced each year and production is confined to the Italian regions of Piedmont and Lombardy. There are only 29 dairies in the world certified to produce this cheese. We visited Caseificio Si Invernizzi in Trecate, Piedmont, Italy, where between 450 and 500 Gorgonzola wheels are made every day.
