The journey of coffee from its discovery to its status as a global beverage is remarkable. It all began in the 9th century when legend has it that an Ethiopian goat herder named Kaldi discovered the coffee bean after noticing his goats became unusually energetic after eating the red berries from a certain tree. This discovery led to the cultivation and trade of coffee across the Arabian Peninsula.
By the 15th century, coffee was being grown in the Yemeni district of Arabia. The beverage quickly gained popularity and spread to Persia, Egypt, and Turkey. Coffee houses, known as qahveh khaneh, became social centers where people gathered to drink coffee, listen to music, and discuss politics. The first coffee house in Europe opened in Venice in 1645, marking the beginning of coffee's journey into Western culture.
As coffee spread throughout Europe, it became a staple in many countries, leading to the establishment of coffee plantations in the Americas and other regions. Today, coffee is enjoyed by millions worldwide, with a rich tapestry of cultures and traditions surrounding its consumption.
