                                The dairy industry in the United States, particularly through regulations set by the California Department of Food and Agriculture (CDFA), categorizes milk and milk products to dictate pricing and use. Understanding what are the four classes of dairy products provides clarity on everything from the fresh milk in your fridge to the aged cheese on your board. These classifications are based on the processing and final form of the product, creating a framework for the vast world of dairy.
