History of Cacao, Cocoa and Chocolate:
Chocolate’s story begins at least 4,000 years ago in the tropical rainforests of the Central Americas.
- Ancient Roots (1900 BC – 1500 AD): The native people used to suck the Cacao beans/white pulp that was sweet and sour as a source of energy. Later, they discovered that the beans could be fermented, roasted, and ground into a bitter, frothy beverage.
- Cacao as Currency: Cacao was so valuable that it was used as money. In Aztec markets, 1 bean could buy a tomato, 10 beans could buy a rabbit, and 100 beans could buy a Slave. It was also a sacred "Food of the Gods" used in rituals and marriages.
- The European Transformation (1500s – 1800s): Spanish explorers brought cacao back to Europe. To suit European tastes, they added sugar, cinnamon, and milk to make Coco shake.
- The Industrial Revolution (1828 – 1900):
- In 1828, Coenraad van Houten, a Dutch chemist discovered a way to treat cocoa beans with alkaline salts to form a cocoa powder, that was easier to mix with water to create a beverage. The process became known as "Dutch Processing" and the chocolate produced was called Cocoa powder or "Dutch cocoa".
- In 1847, the British company J.S. Fry & Sons mixed melted Cocoa butter with sugar and cocoa powder to create a moldable paste that was turned into the world's first solid chocolate bar, that was portable, and edible.
- Milk Chocolate (1875): Daniel Peter and Henri Nestlé in Switzerland successfully added condensed milk to chocolate, creating the creamy flavor that dominates the world today.
Note:
- Cacao refers to the raw plant, the tree, the pods or its fruits
- Cocoa refers to the beans after they have been roasted and processed into Cocoa powder.
Cacao Planting:
Cacao trees require heat, moisture, shade and “biting midges", a tiny fly for pollination. Banana trees are planted nearby to attract biting midges for pollination.
- Planting: Seeds are taken from a ripe pod.
- The Nursery:
- Seeds are usually grown in bags for 4–6 months.
- They graft new plant with a high-yield branch. A grafted tree produces more Cacao fruits, faster and are resistant to local fungus.
- Field Planting: Trees are moved to the plantation, under the shade of taller trees like Coconuts or Bananas.
- Flowering: After 3–5 years, thousands of tiny flowers grow directly on the trunk and main branches.
- Note: Grafted tree will flower in half the time and produce double the yield.
- Pollination: Despite a healthy tree producing up to 50,000 flowers a year, typically fewer than 5% are successfully pollinated.
Unlike most plants, cacao is not pollinated by bees, but by tiny "biting midges", flies that live in the leaf litter on the forest floor. Bananas plants/leafs attract them.
Cacao Harvesting:
A cacao fruit takes about 5–6 months to ripen.
- Identification: Farmers look for a color shift (e.g., green to yellow, or red to orange with stripes).
- The Cut: Pods are harvested by hand.
- Opening: The pods are cracked open to reveal 30–50 beans encased in a sweet, white, citrusy pulp.
Post Harvesting:
This is where the "chocolate" flavor is born. Without these steps, the beans just taste like bitter seeds.
- Fermentation (5–7 Days): The beans and pulp are piled into wooden boxes and covered with banana leaves. The pulp liquefies and drains away, while the temperature rises to 50 C or 120 F, killing the seed and starting the chemical flavor precursors.
- Drying (7–10 Days): Beans are spread on mats in the sun. Moisture must drop from 60% to about 7% to prevent mold.
Cocoa and Chocolate Manufacturing:
- Roasting: The dried beans are roasted in large rotating drums. This develops the chocolate aroma and loosens the outer husk.
- Winnowing: The roasted beans are cracked. A vacuum system blows away the light husks (shells), leaving behind the heavy, flavorful Cacao Nibs
- Note: The nibs are about 50–55% cocoa butter (fat)
- Grinding/Milling:
- The nibs are fed into a mill (stone or heavy steel rollers).
- The friction and heat melt the fat, turning the solid nibs into a thick, dark brown liquid called Chocolate Liquor (or Cocoa Mass).
- Pressing: The chocolate liquor is pumped into a massive Hydraulic Press.
- The press applies immense pressure (up to 6,000 psi) to the liquid mass through a very fine mesh filter.
- The liquid fat is squeezed through the filter. This is Cocoa Butter. It is pale yellow and has a mild chocolate scent.
- The Resulting Cake: What remains inside the press is a hard, dry disc known as a Press Cake.
Finishing the Products
- Cocoa Powder: The "Press Cake" is still a solid block.
- Pulverizing: The cake is broken into small chunks and then ground into a fine dust.
- Sifting: The dust is passed through fine screens to ensure a silky texture.
- Dutching (Optional): Sometimes, the powder is treated with an alkalizing agent (like potassium carbonate) to lower its acidity, making it darker and easier to mix into liquids. This is called Dutched Cocoa.
- Used for: Baking, Hot Chocolate, Ice Cream
- Cocoa Butter
- Filtration: The liquid butter is filtered to remove any remaining solid particles.
- Deodorizing (Optional): If the butter is for white chocolate, it is often kept "natural." If it is for cosmetics (lotions/soaps), it is steam-cleaned to remove the chocolate scent.
- Solidifying: The butter is poured into blocks. At room temperature, it is a brittle solid.
- A Hard Yellow Fat: Used to make Chocolate bars (for smoothness), Cosmetics, White Chocolate
Moniliophthora Fungus and Its Impact in Costa Rica:
- Moniliophthora, a commonly known as Monilia fungus is native to the Colombia and Ecuador. Monilia is aggressive and specifically attacks the developing beans inside the Cacao fruit.
- The Great "Disaster" of 1978: Until the late 1970s, Costa Rica was a major global exporter of cacao. In 1978, Monilia was officially detected in a plantation in the Atlantic zone. It is believed to have been accidentally "imported" via contaminated plant material or even on the clothing of travelers coming from South America.
- The Spread: Within just two years, the fungus swept across the entire country.
- The Collapse: Production plummeted by nearly 80% to 90% almost overnight. Farmers would open pods that looked healthy on the outside, only to find a mass of white, "frosty" spores and rotten beans inside.
- The Economic Shift: The fungus didn't just kill trees; it changed the landscape of Costa Rica. Thousands of farmers walked away from their cacao groves.
- The Rise of the Banana & Pineapple: With the cacao industry in ruins, large agricultural companies moved in, cleared the "dead" cacao forests, and replaced them with massive Banana and Pineapple plantations.
- The Scientific Rescue: Scientists developed Hybrid Varieties that are naturally resistant to Monilia. Costa Rica is currently experiencing a "Cacao Renaissance," but the strategy has changed:
- Quality over Quantity: Farmers no longer try to compete with Africa on volume. They focus on Fine Flavor Cacao using the resistant hybrids and Grafting.
Global Cacao Production:
- The Global Leaders:
- The "Big Two": Currently, West Africa (Ivory Coast, Ghana, Nigeria, Cameroon) the global supply, producing nearly 70% of the world's cacao.
- Latin America (Ecuador, Brazil, Peru, Colombia, Costa Rica)
- Southeast Asia (Indonesia, Malaysia, Vietnam)
