Colby-Jack, or Co-jack/Cojack,[1] is a cheese produced from a mixture of Colby and Monterey Jack cheeses. It is generally sold in a full-moon or a half-moon shape when it is still young and mild in flavor.[2] The cheese has a semi-hard texture. The flavor of Colby-Jack is mild to mellow.[3] Colby Jack cheese is usually produced in Wisconsin, upstate New York, and other regions of North America where cheese is produced.


Colby-Jack has a shiny orange and white marbled look to it.[4]
