Home Roasting Cocoa Beans

Many coffee enthusiasts roast their own coffee beans at home to ensure the highest degree of flavor and quality for themselves. If you are one of those people, you may be surprised to know that you can do exactly the same thing for cocoa beans. Even if you don’t, but just love the flavor of high-quality cocoa or chocolate, you follow some quick, easy steps to roast your own cocoa beans in the comfort of your kitchen.

The processes of roasting coffee and cocoa beans are nearly the same, with just one exceptions: because cocoa beans are more fragile than coffee beans, they have to be roasted at a much cooler temperature. While coffee beans are generally roasted at around 400 degrees Fahrenheit, cocoa beans should never get hotter than 325 degrees.

Other than that, the process is the same. As with coffee beans, they can be roasted in a variety of ways. They can be oven-roasted, air-roasted, drum-roasted in a gas grill, or coffee-roasted. They can even be roasted with a hot air gun. The important details aren’t in how they are roasted, but in the internal and external temperature.

To roast the beans, the first step is to put expose them to a high temperature, a little above 325 degrees, and then gradually lower that temperature of the course of five to 30 minutes (for best results, roast for at least 15 minutes). The point of lowering the temperature is to prevent burning of the outside of the beans while the inside gets appropriately hot. When the beans start to pop (from water evaporation), they are very close to being finished. You want to stop just after most are finished popping, but not so long after that they start to smell burnt. In the end, it’s a trial-and-error system that you will get better at as you gain experience roasting cocoa beans.
