n just a couple of months, Sid Cook, owner of Carr Valley Cheese in Wisconsin, will celebrate the 50th anniversary of earning his Wisconsin cheesemaker’s license. You might think that because he’s spent a lifetime over a cheese vat, he might be ready to retire. But you’d be wrong.

When I sat down with Sid last week to talk cheese and mentioned that he was coming up on a half century of cheesemaking, at first he didn’t believe me. He took a second to do the math. And before he concluded that I was right, he revealed he’d actually been making cheese for several years with his dad before he ever got his license. “I was making my own vats when I was 12 years old,” Sid says. “I always really enjoyed being in the factory, and back then, you opened the kitchen door, and the vats were there.”

Here’s the thing about Sid Cook: he never stops working long enough to thing about how long he’s been working. He may get a little good-natured teasing from his peers for no longer being in the cheese room every day, but that’s because his time is now more valuable thinking about what new cheeses to make. And just to be clear, he’s already made enough cheese in his lifetime for two or three people.
