Introduction

A cup of black coffee

Coffee is a beverage brewed from roasted coffee beans. Darkly colored, bitter, and slightly acidic, coffee has a stimulating effect on humans, primarily due to its caffeine content. It has the highest sales in the world market for hot drinks.

The seeds of the Coffea plant's fruits are separated to produce unroasted green coffee beans. The beans are roasted and then ground into fine particles typically steeped in hot water before being filtered out, producing a cup of coffee. 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 is now a global commodity, it has a long history tied closely to food traditions around the Red Sea. The earliest credible evidence of coffee drinking as the modern beverage appears in modern-day Yemen in southern Arabia in the middle of the 15th century in Sufi shrines, where coffee seeds were first roasted and brewed in a manner similar to how it is now prepared for drinking. The coffee beans were procured by the Yemenis from the Ethiopian Highlands via coastal Somali intermediaries, and cultivated in Yemen. By the 16th century, the drink had reached the rest of the Middle East and North Africa, later spreading to Europe. (Full article...)

Coffee production, Doi Chang, Thailand.
Thailand (formerly Siam) is one of the top 25 coffee producers in the world as of 2014, but its status as a coffee origin has not been widely known. Thailand traditionally produced mainly Robusta for industrial use, but the country has quickly become an exciting emerging origin for specialty Arabica and fine Robusta coffees. The origin is unique in that it exports very little coffee and most of the consumption remains in the country. There is a booming specialty coffee ecosystem where farmers, roasters, cafes and consumers symbiotically co-exist. It is often seen as an example of a working coffee ecosystem for an origin where coffee produced is sustainable from both economic and environmental perspectives. (Full article...)

Iced coffee served in the "Kyoto style", where room temperature water is dripped over coffee grounds for eight hours, and then diluted over ice

Iced coffee is a coffee beverage served cold. It may be prepared either by brewing coffee normally (i.e. carafe, French press, etc.) and then serving it over ice or in cold milk or by brewing the coffee cold. In hot brewing, sweeteners and flavoring may be added before cooling, as they dissolve faster. Iced coffee can also be sweetened with pre-dissolved sugar in water.

Iced coffee is regularly available in most coffee shops. Iced coffee is generally brewed at a higher strength than normal coffee, given that it is diluted by the melting ice. In Australia, "iced coffee" is a common term for packaged coffee-flavored and sweetened milk beverage. Iced coffee is made by brewing hot coffee, and pouring it over ice; Cold brew coffee is made without heat by steeping coffee grounds into lukewarm water. (Full article...)
