Chocolate History & Science

Chocolate originated in Mesoamerica, where the ancient Maya and Aztec civilizations cultivated cacao and consumed it as a bitter, spiced beverage over 3,000 years ago.

Chocolate is made from cacao beans, which are the seeds of the Theobroma cacao tree. The name Theobroma means 'food of the gods' in Greek.

The Aztecs drank chocolate as a cold, frothy, bitter beverage called 'xocolatl,' often flavored with vanilla, chili peppers, and other spices. Sugar was unknown to them.

Spanish explorers, including Hernan Cortes, brought cacao beans back to Spain in the 16th century. The Spanish added sugar to the bitter drink, and it quickly became popular among the elite.

Daniel Peter invented milk chocolate in 1875 by adding condensed milk (developed by his neighbor Henri Nestle) to chocolate. This created a smoother, sweeter product.

Theobromine is the primary stimulant in chocolate. It is similar to caffeine but milder, and it is the reason chocolate is toxic to dogs, who metabolize theobromine much more slowly.

Chocolate bloom occurs when fat or sugar rises to the surface, creating a white, powdery coating. While it looks unappetizing, bloomed chocolate is still safe to eat.

Ivory Coast (Cote d'Ivoire) is the world's largest producer of cacao beans, producing about 40% of the global supply. Most of the world's cacao is grown in West Africa.

Conching is the process of continuously mixing and aerating heated chocolate for hours or days. It develops flavor, reduces acidity, and creates the smooth texture of fine chocolate.

While definitions vary, dark chocolate generally contains at least 50-70% cacao solids. In the US, the FDA requires dark chocolate to contain at least 35% chocolate liquor.

White chocolate contains cocoa butter, sugar, and milk but no cacao solids (cocoa mass), which is what gives dark and milk chocolate their brown color and characteristic flavor.

Raw cacao beans are bitter and flavorless. They must be fermented for several days and then roasted to develop the complex flavors we associate with chocolate.

The Aztecs used cacao beans as currency. A turkey cost about 100 beans, and a fresh avocado cost about 3 beans. Cacao was literally money that grew on trees.

J.S. Fry & Sons of Bristol, England, produced the first modern chocolate bar in 1847 by combining cocoa butter, cocoa powder, and sugar into a moldable paste.

Dogs metabolize theobromine much more slowly than humans, allowing it to build up to toxic levels. Dark chocolate is more dangerous than milk chocolate due to higher theobromine content.
