A History Steeped in Culture and Tradition
Coffee's rich history dates back centuries, with its origins traced to the Ethiopian highlands. Legend has it that a goat herder named Kaldi first discovered coffee when his goats became unusually energetic after nibbling on the berries of a certain plant.
