Patrick Edward McGovern ca. 7000-6600 B.C. It was a mixed fermented beverage of rice, honey, and grape and/or hawthorn ("Crataegus pinnatifida" and "C. cuneata") fruit. The laboratory and collaborators began studying some of the most ancient chocolate from ancient Mesoamerica (ca. 1400-1100 B.C.) in 2004 Jars from Puerto Escondido in Honduras were in the shape of the cacao ("Theobroma cacao") pod or fruit, as if to advertise the contents as being a chocolate beverage. The fruit's sweet pulp contains about 15% sugar, which naturally ferments to a 5 to 7% alcoholic beverage. This beverage might have led to the domestication of the tree.
Cabécar people are among the tallest trees often found in Cabécar tropical home gardens. Lower strata include permanent crops such as coffee ("Coffea arabica") and cacao ("Theobroma cacao"). The lowest stratum is characterized by medicinal plants, shrubs, and tubers, including chili pepper ("Capsicum annuum"), manioc ("Manihot esculenta"), and tiquisque ("Xanthosoma violaceum"). The Cabécar maintain their tropical home gardens by removing undesired underbrush to allow for growth of wild species that can also be harvested to supplement Cabécar everyday needs. Cabécar subsistence farmers practice rotating slash-and-burn agriculture for basic food requirements. This technique is employed during the driest month to clear dense underbrush
