How the Center for Dairy Research helped Wisconsin makers of vastly different cheeses improve production and quality—and bring home top honors in international competitions. Many of the world’s greatest cheeses are made in Wisconsin. It’s a fact that begs the question: How do those cheeses get to be great?A key ingredient is the Center for Dairy Research (CDR), based at CALS and operated with funds from dairy farmers, dairy food manufacturers and processors, and other industry partners. Located within a licensed, operating dairy plant on the UW–Madison campus, its facilities include a cheese pilot plant, a dairy ingredients pilot plant, a sensory lab, an analytical lab and an applications lab, all of which are available to cheesemakers and other dairy manufacturers for trial runs and testing new products. For experienced cheesemakers seeking rigorous additional training, CDR, in partnership with the Wisconsin Milk Marketing Board, offers a three-year program of courses and mentoring leading to certification as a Wisconsin Master Cheesemaker.
