Colby cheese is a semi-hard cheese made from cow’s milk. It’s similar in color to cheddar cheese, but Colby has a milder flavor and is slightly more creamy. The cheese is a healthy source of protein, but it also supplies several other vitamins and minerals that increase its nutritional value.
It is used as a table cheese, for grating and grilling, and in snacks and salads. Colby is sometimes mixed with Monterey Jack to produce a marbled cheese often called Colby-Jack or Co-Jack or as Dupont Cheese calls it Rainbow.
