Episode notes
Forget the legend of Kaldi and his dancing goats, a story invented centuries after coffee was already part of human culture. This deep dive traces how a wild East African shrub became a brewed drink for Sufi monks in 15th-century Yemen and then a nearly half-trillion-dollar global industry.
We follow coffee through Ottoman coffee houses, a papal taste test, colonial plant smuggling, and the enslaved labor of Saint-Domingue and the deforestation of Brazil. Then we turn to the science: the fragile genetics of Arabica versus Robusta, coffee leaf rust, the chemistry of roasting, and how caffeine tricks the brain by blocking adenosine.
