Most people don’t know that chocolate comes from a fruit

You read that right—the deep, dark, chocolaty goodness that you love so much starts with a pod that looks a lot like an elongated melon and grows on a tree. How that very fruity melon-like pod becomes chocolate is a fascinating story.

The cacao beans that are turned into chocolate are the seeds from the fruit of the tree Theobroma Cacao, which grows only within twenty degrees north and south of the equator. Cacao pods come in many different shapes, sizes and colors, and these variations are due to the many genetic differences in the trees. These differences also have a big impact on flavor.

Beyond the genetic differences in the trees, arguably the biggest impacts on the flavor of a cacao bean are post-harvest practices, the two most important of which are fermentation and drying.

Post harvest practices have a big impact on flavor

Unlike coffee beans, cacao beans can’t just be picked and then shipped—they must undergo a period of fermentation that’s not only crucial to developing the flavors in the bean, but also requires extensive skill to master.

Likewise, the beans can’t just be laid out to dry in the sun. The process must be done in a way that ensures maximum flavor without compromising the quality of the bean.

It is this skill in post harvest practices that makes finding fine flavor cacao so difficult. In fact, finding a bean with incredible genetic qualities will still result in poor chocolate if the post harvest practices aren’t done with care and skill.

The first step, of course, is to harvest the beans. Ripe beans are cut down and then carefully broken open, usually with a machete. Care must be taken to not cut into the beans.

Once enough beans are collected they’re brought to a fermentation facility and placed in fermentation boxes. Depending on the bean, they’re fermented for anywhere from three to six or more days. During the fermentation they’re periodically “turned” to ensure the beans ferment evenly. This can be done in several ways, but usually involves moving the beans from one box to another.

The fermentation process must be carefully monitored, and the beans are periodically checked to determine when they’re ready to be turned and when the fermentation is complete.

Once the fermentation is complete the beans are moved onto drying platforms or racks. These are usually covered to protect the beans from the elements, and sometimes are on wheels or have retractable covers that can be pulled back to fully expose the beans to the sun.

The fermentation boxes have openings to allow the pulp to drain out, which is important for proper fermentation.

After the beans have been drying for several days they’re tested for moisture content. When they reach a level near 7% they can be bagged for shipment.

Finally the beans are weighed, bagged, labeled and sent to a warehouse in preparation for shipment.
