Cacao Origin Map

Understanding Cacao Origins: Genetics, Processing and Flavor Examples

Cacao flavor develops through interacting choices and conditions, from planting material and growing environment to fermentation, drying, roasting and manufacture. ICCO’s fine-flavor definition reflects that combination. It does not assign genetics, environment, fermentation and roasting an equal 25% share, or imply that manufacturing cannot change the result.

The 2008 Motamayor study proposed ten major genetic groups. Those groups are useful for understanding diversity, but they are not national flavor categories. Names used for geography, ancestry and trade can describe different things. Our genetics guide explains that distinction; a 2026 Peruvian study also illustrates continuing work on local lineages.

Madagascar: a concrete example is Dandelion’s Ambanja 70% listing, 2024 harvest, with chocolate mousse, yogurt and fresh-plum notes. The maker also describes variation between harvests and roasts. This does not establish an exclusive national red-berry flavor. Production is concentrated in Sambirano, but concentrated geography does not make every harvest taste alike. See the Madagascar guide for source-specific geography and examples.

Ecuador and Peru: both contain varied planting material, producers and processing practices. Nacional ancestry, the Arriba designation and a finished bar’s flavor are distinct subjects. In Peru, a place named Marañón does not by itself identify the named Marañón genetic group. Compare particular producers and makers rather than expecting one flavor from either country. The Ecuador and Peru guides distinguish particular studies, suppliers and maker examples.

Papua New Guinea: smoke is not a required national flavor trait. Historical accounts of smoky beans describe particular supply and drying conditions. The PNG guide distinguishes those accounts from current producer and maker examples. The industry’s smoke-taint guidance treats unwanted smoke exposure as a defect to prevent, not a country signature to seek.

Fat and formulation: use data for the actual lot. A study of 323 accessions grown in Trinidad found genetic variation in butterfat content and bean characteristics. That evidence does not supply fixed Tanzania, Trinidad, Ecuador or Madagascar fat percentages. Research on chocolate rheology also examines interacting effects of fat, particle size and lecithin. Fat alone cannot predict the behavior of a finished recipe.

Fermentation: the appropriate process depends on material, pulp, batch size, equipment and local conditions. The CAOBISCO/ECA guidance describes those variables. A country or genotype label does not establish an exact two-, three- or seven-day schedule. The map’s notes provide context, not a validated fermentation or roast protocol.

These profiles are authored summaries. Named product notes belong to those products and their stated harvests; they are not a statistical national average or our own tasting results. The map is not a live import of thousands of expert reviews, and coverage is not uniform across its entries. Use the linked guides and primary sources to judge the scope of a claim.
