At the Center for Tropical Agricultural Research and Education (CATIE) in Turrialba, Costa Rica, you can touch the history of coffee — and also, if the optimists have their way, part of its future.
Here, spread across 25 acres, are coffee trees that take you back to coffee's origins.
"The story starts in Africa, no? East Africa," says Eduardo Somarriba, a researcher at CATIE, as we walk through long rows of small coffee trees.
