Cacao

Cacao characteristics, types and management

Cacao (Theobroma cacao L.) is a tropical crop grown primarily in regions near the equator. Its beans are processed for use in chocolate, food fats and cosmetic products.

The species belongs to the genus Theobroma and the Malvaceae family. It originated in tropical America and was domesticated in Mesoamerica.

Main cacao groups

Cacao is traditionally discussed in three broad groups from which many varieties, hybrids and clones have been developed:

• Criollo: valued for fine flavor but generally less vigorous and more susceptible to disease.
• Forastero: widely cultivated and typically more productive and resilient.
• Trinitario: a diverse group that originated from hybridization between Criollo and Forastero cacao.

Harvesting and fermentation

Ripe cacao pods are opened and their beans, still surrounded by pulp, are removed for fermentation. Fermentation is essential to developing the aroma and flavor precursors later expressed during roasting. Its duration and handling must be controlled to avoid under-fermentation, excessive acidity or undesirable flavors.

Drying cacao beans

After fermentation, cacao beans must be dried carefully. Important variables include:

• Humidity: moisture must be reduced sufficiently for safe storage.
• Temperature: excessive heat can roast or damage the beans during drying.
• Time: drying should proceed evenly without leaving the beans too moist or making them brittle.

Controlled drying helps stabilize the cacao, preserve quality and reduce the risk of mold during storage.

Storage and bean selection

Dried cacao should be stored in a cool, dry and well-ventilated place, protected from moisture and strong odors. Temperature and humidity must be monitored because cacao beans readily absorb moisture and surrounding aromas.

Beans may be classified by size and physical quality using sieves. Larger, well-formed beans are commonly separated from smaller beans and visible defects. Sorting should also remove broken, moldy, insect-damaged or insufficiently fermented beans before storage or processing.

Cacao in Nicaragua

Nicaragua’s tropical growing regions support the cultivation of cacao, including Criollo- and Trinitario-type material. The final quality of the beans depends not only on genetics and growing conditions, but also on careful harvesting, fermentation, drying, sorting and storage.
