Curd Formation and Cutting

Once the milk has been heated to the desired temperature and the starter culture has been added, rennet is introduced to initiate coagulation. The rennet enzymes cause the milk proteins, primarily casein, to aggregate and form a gel-like structure known as curd. This process typically takes 30 to 45 minutes at a controlled temperature between 88°F and 92°F (31°C to 33°C).

When the curd achieves a firm texture, it is time to cut it. Cutting the curd facilitates whey expulsion, which is essential for the cheese’s texture and moisture content. For Colby Jack cheese, the curd is cut into small cubes approximately ½ inch (1.25 cm) in size. This size balance allows efficient whey drainage without overly hardening the curd.

Cutting is performed using a curd knife or harp, ensuring even and uniform pieces. After cutting, the curds rest for 5 to 10 minutes to firm up slightly before stirring begins. Stirring enhances whey separation and prevents curds from matting together.

Cooking and Washing the Curds

The cooking phase involves gently heating the curds while stirring to expel more whey and develop the desired texture. For Colby Jack, the temperature is gradually increased to around 102°F (39°C) over 30 minutes. This step encourages curd contraction and whey separation but keeps the curds softer compared to harder cheeses like cheddar.

Following the cooking, the curds undergo a washing process specific to Colby cheese production. Washing involves replacing a portion of the whey with cold water, which lowers the curd temperature and reduces acid development. This step retains moisture in the curds and results in a milder flavor and softer texture characteristic of Colby cheeses.

The washing is typically done by draining off about one-third of the whey and replacing it with cold water at approximately 60°F (15°C). The curds are stirred gently during this process to ensure uniform cooling.

Draining, Cheddaring, and Blending

After washing, the curds are drained using cheesecloth-lined molds or perforated containers to remove excess whey. Unlike cheddar, Colby does not undergo traditional cheddaring (stacking and turning slabs of curd to expel whey and develop acidity). Instead, the curds are allowed to settle and drain until they reach a specific moisture content.

At this stage, to make Colby Jack cheese, two distinct curd batches—one Colby (orange) and one Monterey Jack (white)—are prepared separately following the above steps. The Colby curds are colored with annatto, a natural vegetable dye, to achieve the characteristic orange hue.

Once both curds have reached the appropriate moisture and acidity levels, they are blended together by hand or mechanically to create the marbled appearance of Colby Jack. The blending is done gently to maintain the integrity of the individual curds and ensure a consistent marbled pattern throughout the cheese.

Molding and Pressing

The blended curds are transferred into molds lined with cheesecloth for shaping and further whey expulsion. Pressing is applied to consolidate the curds into a firm cheese block while retaining some moisture for the desired texture.

Pressure and duration depend on the size of the cheese wheel or block but generally range from 15 to 30 psi (pounds per square inch) for 4 to 6 hours. During pressing, the cheese is flipped periodically to promote even whey drainage and shape formation.

Salting and Aging

Once pressed, the cheese is removed from molds and salted. Salting is critical for flavor development, moisture control, and inhibition of undesirable microbial growth.

Colby Jack cheese is typically dry salted by rubbing salt on the cheese surface or by brining, where the cheese is submerged in a saltwater solution for several hours. The salt concentration and duration depend on the cheese size and desired flavor intensity.

Colby Jack is a semi-hard cheese that undergoes a short aging period, usually between 1 to 3 months, at temperatures around 50°F to 55°F (10°C to 13°C) with high humidity (85%-90%). This aging allows flavor development and texture refinement without producing overly sharp or hard characteristics.
