The emergence of coffee demand in Europe began with the history and culture of coffee in the 17th century.

In the 17th century, there was a demand for coffee in Europe and began to import small quantities of roasted coffee beans from Yemen. In the 18th century, with the fragrance of European cafes and the sharp increase in coffee bean consumption, the Yemeni mocha alone was no longer enough. It is estimated that the output of coffee beans in Yemen in 2007 ○○ is about 20, 000 tons, which is stretched to meet the rising demand of Europe. The price of beans remained high, and the port of Mocha was busy exporting coffee beans. The word "Mocha" was synonymous with coffee at that time.

At this time, there were still no coffee trees in Central and South America and Asia, and the European powers were optimistic about the huge business opportunities in the coffee cultivation industry and began to intervene and share coffee cakes. Relying on the advantages of the vast overseas colonies and cheap slaves, the great powers soon broke the Ottoman Empire's monopoly on coffee production and marketing, and even eroded the mocha coffee in the Arab market. It can be said that after 1702 ○, the global coffee cultivation industry began to shift from Yemen to the colonies of the great powers in Asia and Central and South America. Java and Brazilian coffee rose strongly, and Mocha fell as important as before, becoming the biggest loser.

Seventeen ⊙⊙ years ago, only Yemen had large-scale coffee cultivation or wild coffee trees, and the Ottoman Empire did not allow coffee to be grown outside Yemen, but there were signs as early as 16 ○○ that it was difficult for the Ottoman Empire to monopolize the high-profit coffee market.
