Alcoholic drinks from Puerto Escondido, lower Ulúa Valley, Honduras
Early Mesoamerican cacao-pulp beverage
Cacao residues in pottery from Puerto Escondido, Honduras, show cacao drinks were served there by about 1100 BCE. The excavators argue the first drink was a weak wine made by letting the sweet pulp around the seeds ferment on its own, before chocolate was made from the seeds. The steps here are a reconstruction; the pulp numbers come from modern cocoa fermentations.

Recipe
No fixed amounts recordedNo recipe survives. The drink is inferred from theobromine in pottery and from how cacao pulp ferments today.
Cacao pulp with the seeds, scooped from ripe pods
Nothing else is known to have been added; the recipe is a reconstruction[henderson2007]
No honey and no chile pepper
Markers of both were absent in four samples tested by GC-MS from the Chotepe phase at Puerto Escondido[henderson2007]

Cacao residues in pottery from Puerto Escondido, Honduras, show cacao drinks were served there by about 1100 BCE. The excavators argue the first drink was a weak wine made by letting the sweet pulp around the seeds ferment on its own, before chocolate was made from the seeds. The steps here are a reconstruction; the pulp numbers come from modern cocoa fermentations. Hanseniaspora thailandica early and Saccharomyces cerevisiae later, as in modern spontaneous cocoa pulp fermentations and Lactobacillus fermentum, the main lactic bacterium of modern cocoa pulp do most of the fermenting.
The drink was made from the sugary pulp, not the bitter seeds that became chocolate. It would have fermented on its own within a day or two, like the pulp in a modern cocoa heap, with no malting or starter.
Modern Malaysian cocoa pulp fermentations (not the ancient drink)
The pulp started at pH 3.3–3.8 and about 25 °C. Yeasts grew fast in the first 24 h and stayed high until 56 h.
In modern cocoa pulp fermentations the pH starts at 3.3–3.8 and ends at 4.4. Alcohol cannot be detected in pottery of these dates, so the strength of the ancient drink is unknown.
At Puerto Escondido in the lower Ulúa Valley, Honduras, 11 of 13 sherds tested positive or borderline positive for cacao (theobromine). The earliest is a spouted bottle from late in the Ocotillo phase, after about 1150 BCE, and cacao use there is documented from at least 1100 BCE. Chemistry alone cannot tell a pulp drink from a seed drink, so the pulp-wine reading is the excavators' argument. At the Olmec capital San Lorenzo, theobromine residues show a liquid cacao product in use between 1800 and 1000 BCE, but whether it was chocolate or a beer fermented from the pulp could not be decided in 2011.
