[その４]
   Prior to the 1700s the Arabs still had a monopoly on commercial coffee cultivation and transportation. But Europeans finally acquired coffee tree seeds and began to cultivate coffee trees. The Dutch are believed to be the first Europeans to produce coffee for profit. They grew coffee trees in their overseas colonies such as Java. Coffee tree seeds were also brought to North America for cultivation, but, they found an ideal environment in Brazil. Today Brazil is one of the leading producers of coffee in the world.
   As the years progressed additional coffeehouses were opened. More efficient methods of production were discovered and new variations of coffee were produced. In 1908 the first drip coffeemaker, using paper filters, was created. Thirty years later instant coffee was invented. Today coffee is the most popular beverage in America and perhaps in the rest of the world.
