Coffee domestication didn’t happen like corn or wheat — and the truth behind your morning cup is stranger than you might think.

This video explores coffee domestication from the wild forests of Ethiopia to Yemen, where humans learned how to transform a nearly aroma-less seed into a drink that would conquer the world.

Surprisingly, Arabica coffee was barely changed genetically by humans. Coffee domestication happened largely through roasting, brewing, selection, and moving the plant across continents. But the history of coffee reveals a hidden cost: every major journey narrowed the genetic diversity of Arabica coffee.
