The operation, in one paragraph.
Ellsworth Cooperative Creamery is a farmer-owned dairy cooperative based in Ellsworth, Wisconsin — the trademarked "Cheese Curd Capital of Wisconsin." Its roots trace to 1903, and today it draws milk from more than 180 patron family farms across Wisconsin and Minnesota, producing roughly 180,000 pounds of fresh cheese curds every day. If you've ever bought a cheese curd in an Upper Midwest grocery store, there's a strong chance it came from here.
The cooperative model.
Ellsworth's structure matters. As a farmer-owned co-op, the 180+ family farms supplying milk are the owners — which aligns the operation around milk quality and farm sustainability in a way a corporate creamery isn't necessarily. The milk is rBST-free, and the curds are made with microbial enzymes rather than animal rennet, making them vegetarian. The co-op has grown by acquisition over the decades (Comstock Creamery in 2011, Wohlt Creamery in 2018) and opened a state-of-the-art specialty plant and retail store in Menomonie in 2022.
Most cheese fans consider Ellsworth's curds the gold standard in the cheese curd world. At 180,000 pounds a day from 180-plus family farms, they've earned the right to set it.
The curds.
Ellsworth's Natural Cheddar curds are white, milky, and clean — the textbook American cheese curd, and the one that has largely defined what the snack tastes like nationally. They scored 9.0 in our review with excellent squeak. The co-op also makes Ranch and Garlic flavored cheddar curds. Read the full curd review →
The shelf-life advantage.
Ellsworth's signature technical achievement is shelf life. Their proprietary packaging removes oxygen while keeping the curds loosely packed, producing a tested 9-month shelf life unopened and refrigerated — far beyond any other curd we've tested. Ellsworth says the cheddar flavor actually enriches the longer the bag stays sealed, and in our testing a months-old sealed bag did read as deeper and more cheddar-forward, at the cost of a little squeak. It's a genuinely unusual property and a real competitive edge.
Beyond curds.
Ellsworth makes more than 80 cheese varieties, including the Antonella half-moon line — pressed-curd semi-soft cheeses infused with natural ingredients, aged, and hand-rolled in spice. The co-op runs retail stores in Ellsworth and Menomonie and ships nationwide Monday through Thursday via UPS with ice packs.
The verdict.
Ellsworth is the most available great curd in America, and the 9-month shelf life is a real, unique advantage. It scores 9.0 — just behind Renard's, and a touch milder in flavor distinctiveness — but for value, availability, and reliability, nothing matches it. The gold standard, for good reason.
