Via a conveyor belt, the now powdery raw mass enters the conche, a large container with an agitator and a water jacket in the outer wall. Depending on the recipe, the chocolate is conched for between six and 24 hours, during which time it heats up considerably due to the frictional energy arising and has to be cooled with the aid of the water jacket. During conching, the individual particles are coated with fat, which gives the chocolate its melting properties. In addition, the unwanted bitter substances are eliminated.

One particular tree, though, does play a prominent role in chocolate-making: the cacao tree.
