Coffee is a beverage that can be drunk hot or cold. It is actually one of the most widely consumed drinks in the world and one of the most widely traded food crops. The coffee drink comes from coffee cherries which grow on trees in Southern Asia, Africa and Latin America. The cherries house the seeds which are known as coffee beans (although not actually true beans) and it is these beans that are processed and roasted to make the drink. The degree to which the beans are roasted affects the taste of the end product. Different varieties of the evergreen coffee tree (Coffea) are cultivated and the most prized is Coffea Arabica which is grown on a commercial scale. Coffea canephora (robusta) is also a widely grown variety and it is more able to fight off than the Arabica. The drink produced from the beans is dark brown and has an acidic flavour and an energising effect on the human body. This stimulating effect is because of the caffeine content and it is the caffeine that also gives the bitter taste. Caffeine is the plant's natural defence against being eaten. Caffeine levels vary between the different coffee varieties. Arabica contains far less than robusta. The compound was first extracted from coffee in 1820 by Friedlieb Runge. Coffee drinking has been around for hundreds of years and the first country of origin appears to be Ethiopia. The popularity of coffee spread from the Muslim countries to the rest of the world where people still love it. Coffee is served in many ways these days. Café's offer a sometimes bewildering range of options from American, espresso, cappuccino and latte to iced coffee or decaf. The most exclusive and costly coffee is Kopi Luwak or Civet Poo Coffee. Civets are particularly good at picking out the best coffee cherries and the seeds contained in them pass through the animal unhurt. The seeds are then collected and turned into coffee. Although some say it is the best coffee in the world, Kopi Luwak is controversial because in many cases the animals are farmed and caged, and animal cruelty has been recorded, making the product unethical for a lot of people. There are many ways you can get your coffee fix now, from roasting and grinding your own beans at home to paying a barrista at a café to make you an espresso.
