Monterey Jack Cheese vs. Colby Jack Cheese

Monterey Jack and Colby Jack are two popular semi-hard American cheeses.

Monterey Jack Cheese vs. Colby Jack Cheese

They share some similarities but have key differences when it comes to their flavor, texture, appearance, ingredients, culinary uses, and nutritional value.

Origins and History

Monterey Jack cheese originated in the 18th century from Franciscan friars in Alta California, who made a semi-firm, creamy, mild cheese from cow's milk. In the 1880s, businessman David Jacks commercialized and popularized the cheese, originally called "Jacks Cheese," leading it to be known as Monterey Jack.

Meanwhile, Colby cheese was first made in 1885 by Joseph Steinwand in Colby, Wisconsin. He made a stirred-curd cheddar, but washed the curds with cold water to create a mellower, higher-moisture cheese. It was named after the nearby city of Colby where his family's cheese factory was located.

Key Takeaway: Monterey Jack dates back to 18th century Spanish missionaries in California, while Colby cheese was invented in the 1880s in Wisconsin.

Flavor and Texture

Monterey Jack has a very mild, slightly sweet, buttery flavor. It is a semi-hard cheese but generally softer and creamier than other cheeses like cheddar. The curds are smooth and it melts very easily.

Colby cheese also has a mild flavor, described as nutty or tangy. It has an open texture with irregular holes. The higher moisture content gives it a softer, springier texture compared to cheddar.

When blended together into Colby Jack, the flavor remains mild and lightly tangy, while the texture becomes even creamier. The cheese pulls apart in shreds when melted.

Key Takeaway: Monterey Jack is extremely mild tasting, while Colby has a subtle nutty tang. Combined in Colby Jack, they create a creamy, melty cheese.


Monterey Jack has a pale white color and smooth, waxy rind. Colby is colored a medium yellow with annatto vegetable dye and also has a waxy rind.

Colby Jack is a marbled cheese with an orange and white pattern created by blending the Colby and Jack curds together before pressing the cheese. This distinct marbled coloration makes Colby Jack easily recognizable.

Ingredients and Make Procedure

The main ingredients for both Monterey Jack and Colby are just cow's milk, rennet, starter cultures, and salt.

They are made using a fairly similar process. The main distinction is that the Colby curds are washed with cold water after cooking, which removes some lactose and acid, resulting in a milder flavor.

Culinary Uses

Monterey Jack is extremely versatile:

  • Melts beautifully, making it perfect for quesadillas, cheeseburgers, grilled cheese, etc.
  • Delicious snacking cheese for cheeseboards due to its mild flavor
  • Commonly used as a base for other flavored cheeses like pepper jack
  • Works well in Mexican dishes, pasta bakes, casseroles and more

Colby also melts very well and can be substituted for Monterey Jack in any recipe calling for melted cheese. Its subtle tanginess gives it a bit more presence.

Colby Jack combines the best properties of both cheeses. Its creamy texture and mellow flavor make it a crowd-pleasing choice for apps, sandwiches, scrambles, mac and cheese, and more cheesy dishes.


Monterey Jack and Colby have very similar nutritional values. Both are high in calcium, protein, Vitamin A, and Vitamin B12. However, Colby Jack typically contains slightly more calories and fat since it is a whole milk cheese blended from two cheeses.
