Gorgonzola is made from unskimmed cow’s or goat’s milk. Penicillium glaucum mold is added to create the blue green veins in the cheese. In creating gorgonzola, starting bacteria is added to milk, along with Penicillium glaucum mold . It is aged in a cave for 3-4 months, with metal rods inserted and removed periodically to allow for mold spores to grow into veins.
