Introduction

A cup of black coffee

Coffee is a beverage brewed from roasted, ground coffee beans. Darkly colored, bitter, and slightly acidic, coffee has a stimulating effect on humans, primarily due to its caffeine content, but decaffeinated coffee is also commercially available. There are also various coffee substitutes.

Coffee production begins when the seeds from coffee cherries (the Coffea plant's fruits) are separated to produce unroasted green coffee beans. The "beans" are roasted and then ground into fine particles. Coffee is brewed from the ground roasted beans, which are typically steeped in hot water before being filtered out. It is usually served hot, although chilled or iced coffee is common. Coffee can be prepared and presented in a variety of ways (e.g., espresso, French press, caffè latte, or already-brewed canned coffee). Sugar, sugar substitutes, milk, and cream are often added to mask the bitter taste or enhance the flavor.

Though coffee has become a global commodity, it has a long history tied closely to food traditions around the Red Sea. The earliest credible reports of coffee drinking pertain to the plant's use among the Sufis of Yemen (southern Arabia) in the middle of the 15th century. Up to the end of the 17th century, most of the world’s coffee was imported from Yemen. But as the beverage gained in popularity, coffee started to be cultivated in Java in the 17th century, as well as in the Americas from the 18th century onward. (Full article...)

Coffee production has been a major source of income for Vietnam since the early 20th century. First introduced by the French in 1857, the Vietnamese coffee industry developed through the plantation system, becoming a major economic force in the country. After an interruption during and immediately following the Vietnam War, production rose once again after Đổi mới economic reforms, making coffee second only to rice in value of agricultural products exported from Vietnam.
