How Chocolate Is Made: From Cacao Bean to Finished Bar

A finished chocolate bar starts life as the seed of a tropical pod and passes through at least seven distinct stages before it reaches a wrapper. Understanding each step helps explain why cocoa — the main raw material — has become one of the most closely watched commodities of the mid-2020s.

From pod to dried bean

Cacao pods grow on Theobroma cacao trees and ripen at different times, so harvesters use machetes to cut only mature pods without damaging the tree's flowers, according to a bean-to-bar process guide published by Alpha Foodie. Workers then break the pods open, often using a wooden muddler or hammer, to scoop out the beans, which are still coated in white pulp.

The beans and pulp are then piled together, often under banana leaves, or placed in lidded boxes to ferment. Alpha Foodie's guide describes a traditional process of around five days — sometimes slightly longer — and a modern dehydrator method that can run five to ten days. During fermentation internal temperatures reach roughly 40–50°C (104–122°F); workers drain liquid and mix the beans daily. The beans visibly change color from purple to reddish-brown to dark brown as flavor compounds develop and astringency is reduced, Alpha Foodie's guide states.

Once fermentation ends, the beans are dried — typically in the sun or with forced air at around 40°C — until their moisture content is low enough for shipping and long-term storage.

Roasting, winnowing and grinding

At the processing plant, dried beans are roasted, commonly for around 15 to 20 minutes at roughly 120°C (250°F) for a light roast, though manufacturers vary time and temperature depending on the flavor they want. Roasting removes remaining moisture, develops flavor, reduces bacteria and loosens the outer shell from the bean's inner kernel.

The cracked shells are separated from the kernels in a step called winnowing, leaving behind cocoa nibs. Cacao nibs are roughly half cocoa butter and half solid cocoa content by composition, per the Alpha Foodie guide. The nibs are then ground into a paste; friction from grinding melts the cocoa butter and produces a thick liquid known as chocolate liquor, into which sugar, milk solids or vanilla may be added depending on the recipe.

Conching and tempering

The ground paste then undergoes conching — extended mixing that is distinct from grinding. Conching removes unwanted volatile acids and incorporates air to refine and mature the chocolate's final flavor. UK producer Pump Street Chocolate says its own conching process is not rushed and typically runs three to four days, after which the chocolate is left to mature for about 30 days before further processing.

Finally, the chocolate is tempered — carefully heated and cooled to form a stable crystal structure — before being poured into molds, cooled, and released as finished bars ready for wrapping and distribution.

Why cocoa supply is in the news

Cocoa futures reached a 50-year high of nearly $12,906 per tonne in December 2024, according to data tracked by Trading Economics. As of October 23, 2026, cocoa was trading around $5,558 per tonne, down about 12% from a year earlier but still far above pre-2024 levels; prices had spiked to roughly $6,771 per tonne in late August 2026 before easing.

Côte d'Ivoire and Ghana together account for more than half of global cocoa production, according to analysis published by FoodNavigator. The outlet reported that excessive rainfall, insufficient moisture in other periods, rising plant disease and declining soil quality are reducing yields in West Africa and discouraging some farmers from reinvesting in their land — a trend it described as a structural rather than temporary threat to supply. Diversification efforts in Ecuador, Peru, Colombia and Brazil are underway, but FoodNavigator noted that meaningful diversification will take time, leaving West Africa as the backbone of global supply for now.

The International Cocoa Organization's August 2026 Quarterly Bulletin reported that world gross production for the 2024/25 season rose 8.5% year-on-year to 4.733 million tonnes, while world grindings — a measure of processing demand — fell 3.3% to 4.649 million tonnes. The bulletin estimated a global supply surplus of 37,000 tonnes and said end-of-season stocks rose nearly 3% to 1.309 million tonnes, lifting the stocks-to-grindings ratio to 28.2%. The ICCO also noted growing concerns about an anticipated El Niño event later in 2026 and said market sentiment remains highly sensitive to production risks in major growing countries.

FoodNavigator reported that chocolate manufacturers raised prices in 2024 and 2025, but by 2026 major premium brands had reached the limits of their pricing power as sales growth slowed. In response, some manufacturers are exploring reformulation, reduced cocoa content and cocoa-free alternatives to manage costs, while also funding farmer training and farm-rejuvenation programs intended to support long-term supply.
