Formaggi Zanetti Parmigiano Reggiano
Similar to many retailers, Costco sells a lot of cheeses. However, only a handful are comparable to the Kirkland Signature Parmigiano Reggiano. Since they import the hard cheese from Italy, it can’t just be called “Parmesan” and it can hold its name. Costco sources the cheese from Formaggi Zanetti, which specializes in exporting their cheese all over the world. Many companies sell cheese from Formaggi Zanetti, which sources 100% local Italian milk.
