A guide to Colby and Colby-Jack cheese — mild American classics. How Colby differs from cheddar, what makes it softer, and how to use it.
Colby and its marbled cousin Colby-Jack are quintessentially American cheeses — mild, mellow, and made for everyday eating. Often mistaken for cheddar, Colby is actually made differently, which gives it a softer, moister, gentler character all its own.
What Colby Is
Colby is a semi-hard cow's-milk cheese that originated in the town of Colby, Wisconsin, in the 1880s. It looks a lot like cheddar — usually colored orange with annatto — but it's made by a different process. The defining difference is a step called "washing the curd": cold water is added to the curds during production, which rinses away some acidity and lactose. The result is a softer, moister, milder, springier cheese than cheddar.
Colby vs. Cheddar
Though they resemble each other, the two cheeses diverge in important ways. Colby skips the "cheddaring" step and instead washes its curds, leaving it higher in moisture, softer, and milder, with a more open, slightly springy texture. Cheddar is firmer, denser, and develops sharp, tangy flavors as it ages. Colby, by contrast, is meant to be eaten young and doesn't age into sharpness — it stays mellow and mild.
Flavor and Texture
Colby is mild, sweet, and milky, with only a gentle tang. The texture is supple, moist, and a little springy, making it easy to slice and pleasant to snack on. Because it's a high-moisture cheese, it doesn't keep as long as cheddar and is best enjoyed relatively fresh.
What Is Colby-Jack?
Colby-Jack (sometimes "Co-Jack") is a marbled blend of orange Colby and pale Monterey Jack, pressed together so the finished cheese shows a marbled orange-and-white pattern. Both base cheeses are mild and melty, so Colby-Jack is a smooth, gentle, all-purpose cheese popular for snacking, sandwiches, and melting. Its two-tone look also makes it attractive on cheese and snack platters.
How to Use Colby and Colby-Jack
Both are versatile, mild melting and snacking cheeses. Slice them for sandwiches and burgers, cube them for snack trays and lunchboxes, shred them for quesadillas, nachos, casseroles, and macaroni and cheese, or simply eat them with crackers and fruit. They won't overpower other flavors, which makes them especially good for kids and for dishes where you want melt without a strong cheese taste.
Buying and Storing
Colby and Colby-Jack are widely available in blocks and shreds. Because they're high in moisture, wrap them well and keep them refrigerated, using within a couple of weeks. Buying blocks and grating as needed gives better melt and flavor than pre-shredded.
