Opening the Pod
Each journey to chocolate begins by carefully cracking open cacao pods — mindful not to damage the precious beans inside.
Here, 32 freshly harvested pods yield about one gallon of beans, enough for a small batch fermentation.
Fermentation: Awakening the Beans
Fermentation is cacao’s essential transformation — a natural, microbial dance that unfolds over about seven days in Hawaiʻi’s climate.
Large batches and insulated containers are key. We use an igloo cooler lined with rinsed banana leaves, which gently cradle the beans while keeping the heat in. This warmth activates the microbes that convert sweet pulp sugars into complex flavor precursors.
The cooler’s walls carry “memory” from past ferments — encouraging a healthy community of beneficial microbes to flourish. When mold appears, we clean and start fresh, respecting the delicate balance.
Early Signs
The beans are juicy at first — that pulp liquid is drained in the first couple of days. If you’re adventurous, it can be savored as a sweet, tropical drink (consume responsibly).
The ferment’s aroma shifts from sweet to sour with hints of alcohol as yeasts work. For the first two days, the lid remains sealed tight to preserve warmth and exclude oxygen.
Turning the Beans
From day 3, the pulp lessens, and heat builds inside the pile — like a miniature compost heap alive with billions of microorganisms.
At days 3, 5, and 7, the beans are carefully “turned” to introduce oxygen, which encourages beneficial aerobic microbes and improves fermentation quality.
Temperatures rise between 110°F and 120°F (43°C to 49°C). The longer the beans stay warm, the richer the flavor development.
Monitoring Progress
Fermentation completes when the temperature falls, typically after about seven days. Sometimes an extra day is needed for perfect results.
Cut tests reveal fissures opening on the beans — a sign of proper fermentation. Beans with closed fissures may benefit from more time.

Our ferments carry aromas of berries, raisins, and a strong, vinegary tang — a signature of healthy cacao transformation.
Drying: Capturing the Flavor
Freshly fermented beans hold about 60% moisture and require sun drying down to 7–8%.
We built a drying house with wire mesh racks, spreading beans in thin layers to dry for 2 weeks to a month, depending on weather.
During drying, chemical reactions continue inside the beans, deepening flavor and reducing acidity. Mold is uncommon due to the acidic nature of the cacao pulp.
Once dried, beans are stored in breathable grain bags that protect from pests and dust, while allowing air circulation. Properly dried beans can be stored for years.
This is what gets sold and traded as a commodity on the world market.
