Final answer:
The goat herder associated with the discovery of coffee is known by the name Kaldi. The trade of coffee began in Yemen, with Arabica beans being one of the world's most consumed coffee types, demonstrating historical interconnectedness.
Step-by-step explanation:
The young goat herder who is credited with the discovery of coffee is not explicitly named in the historical texts, but the story is a popular legend. According to Ethiopian folklore, it was a goat herder named Kaldi who first recognized the potential effects of the coffee plant when he noticed that his goats became more energetic after eating the berries from a certain tree. This led him to try the berries himself and eventually to the discovery of coffee as a beverage. Coffee cultivation and trade began in the Arabian Peninsula, primarily in Yemen, with the port city of Mocha becoming a major center for coffee export. The Ottoman Empire played a significant role in spreading the coffee-drinking habit to Europe and the rest of the world. Arabica coffee, originating from the Arabian Peninsula, highlights the interconnectedness of cultures and the global influence of products over time.
