Wisconsin Master Cheesemaker

Burnett Dairy Cooperative is home to Wisconsin Master Cheesemaker®, Bruce Willis.

What does it mean to be a Wisconsin Master Cheesemaker®?

The Wisconsin Master Cheesemaker® program is the only one of its kind outside of Europe. For cheesemakers, it provides the opportunity to reach the highest levels of their craft. For buyers, it provides unparalleled quality assurance, innovation and expertise.

Administered by the Center for Dairy Research at the University of Wisconsin-Madison, the program is open to veteran Wisconsin cheesemakers with a minimum of 10 years’ experience in Quality Assured plants. Candidates can seek certification for up to two cheese varieties each time they enter the three-year program. They must have been making those specific varieties for at least five years.

Burnett Dairy can proudly say we master in Mozzarella, Colby, Monterey Jack, Fancy Jac and Cheddar cheeses.

Only certified Master Cheesemakers® are eligible to use the Master’s Mark® on their products. Behind this distinctive blue mark on the label is an assurance of quality that you just can’t get anywhere else. That mark, which can only be used by the 56 Wisconsin cheesemakers who’ve earned it, tells quite a story.

It tells you that experience, technical expertise and artistry went into making that cheese. And, it means that you can be confident that you’ve chosen the best cheese from the only place in America where cheesemakers can become true Masters of their craft – Wisconsin.
