Cocoa drying is crucial in the process of making cocoa worthy of a chocolate bar.
It may not sound special, but it’s actually one of the most important steps in transforming cacao from fruit to chocolate. Without carefully drying the cocoa beans, they’d spoil before ever reaching your favourite treats.
Done right, drying preserves flavour, prevents spoilage, and lays the foundation for exceptional cocoa. But it’s a careful balancing act. Dry too slowly and you risk mould. Dry too quickly and beans become bitter.
In this guide, we’ll dive into why drying cocoa beans matters, the methods farmers use, how to tell when beans are perfectly ready, and the climate challenges making it all trickier. Ready to discover the art (and science) behind perfectly dried cocoa? Let’s take a closer look.
Why Dry?
Growing cocoa is a meticulous process. After harvesting, the beans are carefully fermented, dried, roasted, and then cracked into cocoa nibs. These nibs are often ground into a rich cocoa paste, the essential base from which cocoa powder is made.
Drying cocoa beans plays a critical role in this journey. Since freshly fermented beans still contain high moisture, sometimes even up to 60 percent! At this level, the beans are too wet. If left undried, they could spoil or develop mould. Drying the beans brings moisture down to around 6 to 8 percent, so that they can be safely stored and transported.
But drying cacao isn’t just about preservation. It’s also about the flavour. The slow removal of water allows the beans’ natural chocolate notes to develop, setting the stage for roasting. If drying is rushed, uneven, or interrupted by rain, the beans may taste sour, smoky, or even musty.
For small cocoa farmers, drying cacao isn’t just a step in the process, it’s their livelihood. Well-dried beans sell for a better price, while poorly dried ones can mean money lost.
Traditional vs. modern methods
Cocoa drying isn’t a one-size-fits-all job, it’s got history, culture, and a touch of local flair baked in. Across the world, farmers have been perfecting their own ways of drying beans for generations, shaped by climate, tradition, and whatever tools are on hand. These days, you’ll often see a clever mix: old-school know-how meets modern tech, all in the name of flavour, efficiency, and consistency.
Sun drying
Sun drying is the oldest and most common method for drying cocoa. Farmers spread the beans on raised wooden racks, bamboo mats or concrete floors, letting the sun slowly draw out the moisture. They turn the beans regularly to make sure they dry evenly and prevent mould.
This method is delicate and sensitive to weather conditions. Too much sun can over-dry the beans, but too little can slow the process and increase spoilage risk. The entire process can take up to a week, and a sudden rainstorm can undo all that work.
But when it’s done well, sun drying brings out a rich, layered flavour that mechanical methods just can’t match. Plus, it’s energy-efficient and sustainable, a true tradition of cocoa craftsmanship. On our travels through Mexico and Bolivia, this is the method we’ve seen most smallholder farms using.
Mechanical drying
When the weather is unpredictable, or when farmers need to dry larger batches, mechanical dryers come into play. These machines use warm, controlled air to reduce moisture quickly and evenly, giving a consistent result every time.
While mechanical drying is reliable, it does require energy and investment. For many smallholder farmers, only access to shared facilities or cooperatives makes this method possible, helping them process beans efficiently without sacrificing quality. More advanced farms, such as large-scale producers in Ghana and Cameroon, have easier access to mechanical dryers, which helps them manage larger harvests and adapt to shifting weather.
Climate Challenges in Cocoa Drying
Unfortunately, climate change is throwing a curveball at cocoa drying. Longer rainy seasons and sticky humidity mean beans take forever to dry, and mould is always lurking around the corner. For smallholder farmers, that’s not just an inconvenience. Losing even part of a harvest to poor drying can mean losing hard-earned income.
Viridiana de la Cruz of Hacienda RC is one smallholder farmer facing exactly this problem. As we got to know Viridiana when travelling through Comalcalo, Mexico, she explains how climate shifts have affected her beans.
“We had many problems with the sun because in March it starts with a lot, a lot of sun,” she tells us. “Maybe because we do not have the ideal infrastructure, then we suffer because of too much sun. Because the grain, if it is not dried in a certain way, the pores close and inside, it cannot get its moisture out.”
As part of our micro-project series, we helped Viridiana solve the challenge of consistent bean drying by sponsoring the construction of a drying house at her Hacienda RC, shared with neighbouring farm, Finca Cacayo too. It’s simple facilities like this that protect beans from unpredictable weather and ensure better quality cocoa.
How to tell if the drying is finished?
Producers often rely on a simple but effective trick: the crack test. By biting or breaking a bean, farmers can tell how it’s drying. A properly dried bean will break with a sharp snap and reveal a brittle interior. If it bends or feels soft, moisture is still too high.
But the crack test isn’t the only way to tell if beans are ready. Some farmers use moisture meters for a precise reading, while others rely on experience, judging dryness by weight, texture, and appearance. Fully dried beans feel lighter, harder, and often have a slightly shrivelled look with a uniform color.
This stage takes patience and practice, but combining methods ensures the beans are perfectly ready for roasting.
How cocoa drying develops flavour
If fermentation lays the foundation, drying is where the house is built.
As moisture escapes, acids formed during fermentation evaporate, leaving behind balanced chocolate notes. Poorly dried beans can taste flat or overly bitter. Well-dried beans, on the other hand, reveal the full complexity of the cocoa itself: fruity, nutty, and deeply aromatic.

Use of chemicals when drying
Some big producers reach for chemical sprays to hurry things along or keep mould at bay. Sure, it’s faster, but it can strip away the cocoa’s natural character and raise red flags for health and the environment.
At The Cocoa Circle, we take the scenic route. We team up with farmers who trust the sun (and a little gentle airflow) to do the job, no shortcuts, no chemicals, just patience and care. The payoff? Cocoa that keeps its true flavour, pure and delicious, just the way nature intended.
What Happens After?
Once the beans hit that sweet spot of moisture, it’s time for the next act: sorting, bagging, and tucking them safely away. Properly dried cocoa can sit happily in storage for months without losing quality, giving farmers the freedom to sell when the timing (and price) is right.
From there, the beans are off on their grand adventure: roasting, grinding, refining… and finally transforming into the chocolate you know and love.

The Bigger Picture
Drying cocoa beans might seem like a simple step, but it’s one of the most crucial parts of cocoa’s journey from bean to bar (or bean to baking). It impacts flavour, safety, storage, and income for farmers.
Supporting smallholder farms with proper drying facilities, training, and resources ensures that more people can enjoy delicious chocolate while sustaining the livelihoods of those who grow it.
