Coca-Cola is one of the most popular drinks in the world and this is probably due to its signature taste. In fact, the original recipe that gives it that signature taste is only known to 2 people who aren’t allowed to travel together, and the recipe itself is kept in a secure vault.

We know of one ingredient — the one that gives the drink caffeine — the kola nut. In fact, it’s one of the ingredients that the drink is named after. This nut is from West Africa, and the cultivation has been happening across many civilizations. In Europe, it was introduced around 1,500 and by the 19th century, many products started using it.
