Well, I suppose nothing can really guarantee quality--the requirements simply make it more difficult to screw up. For instance, pulling from this article[0]: >In the highly sanctioned world of Parmigiano-Reggiano, cows graze in pastures; their diet must consist of at least 75 percent local grass. Here in the United States, the U.S. Food and Drug Administration (FDA) doesn’t mandate diet, and cows typically aren’t pastured; manufacturers reported using various feeds, including hay, corn, soybeans, and grains. ... > Another factor: raw versus pasteurized milk. In Italy, Parmigiano-Reggiano is always made from raw milk. In the States, the milk is typically pasteurized first. This step kills off potentially dangerous organisms and yields a more consistent product. The downside? The heating process also kills off flavorful microorganisms. ... >The aging step affects both flavor and texture. Once the wheels come out of the salt bath, they’re set on racks in climate-controlled rooms to age. As the cheese sits, lactic acid forms, and the acid causes proteins in the cheese to squeeze together, which in turn forces out moisture. Parmigiano-Reggianos are required to age for at least 12 months, though most are left for 24. Meanwhile, the FDA mandates a minimum of just 10 months for Parmesan. Thus, the domestic cheeses tended to be rubbery, while the imports were dry and crumbly. --- So again, you could make a hard cheese that follows none of the requirements but still tastes pretty good. You could also make a Parmigiano-Reggiano that tastes like crap. But if you follow all of the standards, you will more likely come alot closer to replicating the taste of what we associate with Parmigiano-Reggiano than a vat of hard cheese that some guy cooked up in his basement. The standards are specifically there to curtail the shortcuts (less aging, lower-quality ingredients) that unscrupulous companies try to sneak into their cheeses and market as premium, "aged" Parmesan.
