Cut and graded by an independent third party. 8 sites, 5 tonnes fermented.
The cut test is how the industry judges fermentation: slice open 100 beans, count and grade them. Fully brown is the target colour. Fissuring — the cracked internal structure of a well-fermented bean — is graded 1 to 4, with 4 the highest.
Four monitored batches and four fermented traditionally were sent to a third-party professional cacao bean grading authority. GOcacao did not conduct or supervise the evaluation.
Beans per 100 — a 20.3% improvement.
Each bean in the sample is cut and classified — fully brown, partially fermented, or defective — and fissuring is graded. The fully brown count and the grade 4 fissuring count are the two indicators buyers, exporters and craft producers use internationally.
EVALUATOR — Third-party cacao bean grading authorityGrade 4 fissuring indicates that flavour precursors formed during the ferment.
A 55.2% reduction in batch-to-batch variation.
Recorded in the field rather than under laboratory conditions, across a range of microclimates, cooperative structures and levels of farmer experience.
Coefficient of variation measures how much batch quality swings around the mean. Traditional fermentation sits at 22.67%. GOcacao cuts it to 10.17%.
For buyers and chocolate makers, consistency matters as much as peak quality.
Measured on grade 4 fissuring across graded samples.
Northern Thailand. Mountain-zone fermentation, high diurnal temperature variance.
Two cooperative sites. Northern plains. One of the highest-yield deployment locations.
Northern cooperative. 13 active farmers, 30 joining. A former orange-growing community that moved to cacao production.
Central Thailand. Humid lowland climate. Close-proximity monitoring of multiple boxes.
Samut Sakhon Province. Coastal microclimate with high ambient humidity.
Urban cooperative and R&D base. Also used for controlled comparison trials.
Eastern border region. Dryer conditions, lower humidity. Algorithm trained on variance.
Gulf of Thailand coast. Tropical coastal climate, high heat and humidity loading.
5 Tonnes
Across 8 sites, diverse microclimatic conditions.
Farmers capture 5–7% of what a finished bar is worth. Better fermentation produces better beans, and better beans earn a premium.
Standard cacao in Thailand fetches around 90 baht a kilogram. Beans fermented properly, with the data to prove it, earn a premium on top of that — de'Finnitive Chocolates pays 25–45% above commodity price for them. In Phrae, GOcacao-monitored batches now reach 130 baht a kilogram.
A difference of 40 baht per kilogram, per batch.
For years, the Phrae community grew oranges. Then orange prices collapsed — falling to as low as 10 baht per kilogram. The community had hundreds of cacao trees and land well-suited to the crop, but no understanding of the fermentation process that separates raw cacao from high-value product.
Without proper fermentation, cacao is worth little — unfermented or poorly fermented beans are rejected by premium buyers. The community had the trees but was capturing none of the value.
GOcacao deployed devices and ran hands-on fermentation training with the Phrae cooperative. The device signalled the turn point on each fermentation cycle.
Within the first season the cooperative was achieving 130 baht/kg, against roughly 90 baht/kg for unassisted cacao and 10 baht/kg for their former orange crop. With 50 kg batches running 12–18 times per year, each farming family now earns 78,000–117,000 baht annually from cacao alone.
13 farmers are currently active and 30 more from surrounding areas plan to join next season.
