From Cocoa to Confection: Evolution of Chocolate from Ancient Beans to Modern Bars

Story of chocolate as we know it today begins with the word “conche” and its verb form, “conching.” This process was a closely guarded secret in the valleys of Switzerland long before it revolutionized the world with melt-in-the-mouth chocolate bars. Rodolphe Lindt kept the conching process to himself for 20 years until 1899, when he sold it to Johann Rudolf Sprüngli-Schifferli, a fellow chocolate manufacturer.

Where did Chocolate’s journey start?

Chocolate’s journey starts with cocoa, a bean with a history dating back to the 4th millennium BC in the Ecuadorian rainforests. By the 2nd millennium BC, the word “kakawa” had gained prominence in Mexico, where the Aztecs enjoyed a spicy drink called “Xocolatl.” However, it wasn’t until European explorers “discovered” it that chocolate began its global ascent. In 1528, the conquistador Hernán Cortés brought cocoa to Europe. By 1544, chocolate had reached the Spanish court and was enjoyed as a drink.

Centuries later, the cocoa tree was scientifically named Theobroma Cacao L. by Carl von Linné, meaning “food of the gods” in Greek. Since then, chocolate has continued to captivate people worldwide.

Solid chocolate, as we know it, was still centuries away from being perfected. The Italian “cioccolatieri,” or traveling craftsmen, began showcasing their chocolate-making skills at fairs across Europe. Chocolate making was a labour-intensive process requiring significant skill and patience. One of the first Swiss individuals to master this art was François-Louis Cailler, who opened Switzerland’s first chocolate factory in Corsier-sur-Vevey in 1819. Cailler’s brand remains the oldest existing chocolate brand in the world today, though chocolate bars were yet to be invented.

In the 19th century, young chocolate producers in Switzerland, France, and England spent years experimenting, facing many failures, and striving for success. France was home to the first single-bar manufacturing plant in 1846, but the chocolate was still bitter, hard, grainy, and left an unpleasant taste.

It wasn’t until 1847 that England produced the first palatable chocolate bar, although it was still rough and gritty. These early attempts were far from the smooth, delectable chocolate we enjoy today. Yet, these innovations laid the groundwork for future developments.

Switzerland’s contribution to Chocolate making?

Switzerland’s contribution came a few decades later when the process of conching was perfected by Rodolphe Lindt, which significantly improved the texture and flavour of chocolate. This marked the beginning of the modern chocolate era, transforming chocolate from a coarse, bitter treat into a smooth, luxurious confection that continues to delight people around the globe.
