A cup of black coffee
Coffee is a brewed drink prepared from roasted coffee beans, the seeds found inside "berries" of the Coffea plant. Coffee plants are cultivated in over 70 countries, primarily in equatorial Latin America, Southeast Asia, India and Africa. The two most commonly grown are the highly regarded arabica, and the less sophisticated but more hardy robusta. The latter is resistant to the coffee leaf rust (Hemileia vastatrix). Once ripe, coffee beans are picked, processed, and dried. Green (unroasted) coffee beans are one of the most traded agricultural commodities in the world. Once traded, the beans are roasted to varying degrees, depending on the desired flavor, before being ground and brewed to create coffee. Coffee can be prepared and presented in a variety of ways. Coffee is slightly acidic (pH 5.0–5.1) and can have a stimulating effect on humans because of its caffeine content. It is one of the most consumed drinks in the world.
The energizing effect of coffee was likely first discovered in the northeast region of Yemen. Coffee cultivation first took place in southern Arabia; the earliest credible evidence of coffee-drinking appears in the middle of the 15th century in the Sufi shrines of Yemen. In East Africa and Yemen, coffee was used in native religious ceremonies that were in competition with the Christian Church. As a result, the Ethiopian Church banned its secular consumption until the reign of Emperor Menelik II of Ethiopia. The beverage was also banned in Ottoman Turkey during the 17th century for political reasons and was associated with rebellious political activities in Europe. An important export commodity, coffee was the top agricultural export for twelve countries in 2004, and it was the world's seventh-largest legal agricultural export by value in 2005. Some controversy is associated with coffee cultivation and its impact on the environment. Consequently, organic coffee is an expanding market.
Many studies have examined the health effects of coffee, and whether the overall effects of coffee consumption are positive or negative has been widely disputed. The majority of recent research suggests that moderate coffee consumption is benign or mildly beneficial in healthy adults. However, coffee can worsen the symptoms of some conditions, largely due to the caffeine and diterpenes it contains.
An Irish coffee being prepared
|Irish coffee is a cocktail consisting of hot coffee, Irish whiskey, and sugar (some recipes specify that brown sugar should be used, and that fresh cream should be floated on top), stirred, and topped with thick cream. The coffee is drunk through the cream. The original recipe explicitly uses cream that has not been whipped, although drinks made with whipped cream are often sold as "Irish coffee".
Although different variations of coffee cocktails pre-date the now-classic Irish coffee by at least 100 years, the original Irish coffee was invented and named by Joe Sheridan, a head chef at Foynes, County Limerick but originally from Castlederg, County Tyrone. From the mid 19th Century, earlier versions such as the Pharisäer and the Fiaker were served in Viennese coffee houses, both coffee cocktails served in glass, topped with whipped cream. The former was also known in northern Germany and Denmark around this time. Around the turn of the 20th century the coffee cocktail menu in the Viennese cafés also included Kaisermelange, Maria Theresia, Biedermeier-Kaffee and a handful of other variations on the theme.
