87-601: One of the high points in this woreda is Mount Wanchi (3386 meters). Coffee is an important cash crop of Ambo; over 50 square kilometers are planted with this crop. This woreda is home to Dr. Merera Gudina , the founder and chairman of the Oromo People's Congress (OPC). Although the OPC has a large following in Ambo, Human Rights Watch has received reports of kebele officials imprisoning people for campaigning for or providing support to

174-459: A drupe (commonly called a "cherry") 10–15 mm in diameter, maturing bright red to purple and typically containing two seeds , often called coffee beans. Endemic to the southwestern highlands of Ethiopia , Coffea arabica is grown in dozens of countries between the Tropic of Capricorn and the Tropic of Cancer . It is commonly used as an understory shrub. It has also been recovered from

261-414: A 9th-century Ethiopian goatherd, first observed the coffee plant after seeing his flock energized by chewing on the plant. This legend does not appear before 1671, first being related by Antoine Faustus Nairon, a Maronite professor of Oriental languages and author of one of the first printed treatises devoted to coffee, De Saluberrima potione Cahue seu Cafe nuncupata Discurscus (Rome, 1671), indicating

348-537: A coffee berry and lays 35 to 50 eggs. Inside, the offspring grow, mate, and then emerge from the commercially ruined berry to disperse, repeating the cycle. Pesticides are mostly ineffective because the beetle juveniles are protected inside the berry nurseries, but they are vulnerable to predation by birds when they emerge. When groves of trees are nearby, the American yellow warbler , rufous-capped warbler , and other insectivorous birds have been shown to reduce by 50 percent

435-564: A cupful. It is composed of water and the fruit from a bush called bunnu. Thriving trade brought many goods, including coffee, from the Ottoman Empire to Venice. From there it was introduced to the rest of Europe. Coffee became more widely accepted after it was deemed a Christian beverage by Pope Clement VIII in 1600, despite appeals to ban the "Muslim drink". The first European coffee house opened in Venice in 1647. The Dutch East India Company

522-485: A first language by 90.92%, and 8.37% spoke Amharic ; the remaining 0.81% spoke all other primary languages reported. The majority of the inhabitants professed Ethiopian Orthodox Christianity , with 74.16% of the population reporting they practiced that belief, while 18.77% of the population said they held traditional beliefs, and 6.07% were Protestant . 9°00′N 37°45′E  /  9.000°N 37.750°E  / 9.000; 37.750 Coffee Coffee

609-670: A huge wild population of 13.5 to 19.5 billion individuals throughout its native range, C. arabica is still considered endangered on the IUCN Red List due to numerous threats it faces. Due to being an understory plant, it requires standing forest, making it highly susceptible to the historically significant deforestation levels in Ethiopia; prior to major deforestation, forest cover was thought to be between 25–31% of Ethiopia's total land surface, but has dropped to just 4%, and deforestation still continues. In addition, climate change may have

696-527: A major effect on growing areas for wild C. arabica in Ethiopia due to its high-temperature sensitivity, and estimates indicate that population could reduce by 50–80% with a 40–50% reduction in area of occupancy by 2088; climate change can also impact reproductive success. In addition, the main pest of coffee, the coffee berry borer ( Hypothenemus hampei ) may benefit from climate change and colonize higher altitudes that were formerly too cold for it, which can also impact coffee populations. The conservation of

783-520: A mulch. They are especially appreciated by worms and acid-loving plants such as blueberries. Climate change may significantly impact coffee yields during the 21st century, such as in Nicaragua and Ethiopia which could lose more than half of the farming land suitable for growing (Arabica) coffee. As of 2016, at least 34% of global coffee production was compliant with voluntary sustainability standards such as Fairtrade , UTZ , and 4C (The Common Code for

870-502: A problematic invasive species. Coffee has been produced in Queensland and New South Wales of Australia, starting in the 1980s and 1990s. The Wet Tropics Management Authority has classified Coffea arabica as an environmental weed for southeast Queensland due to its invasiveness in non-agricultural areas. The first written record of coffee made from roasted coffee beans (botanical seeds) comes from Arab scholars, who wrote that it

957-476: A sign of quality. In 2023, several large coffee roasters dropped the "100% Arabica" declaration previously residing on some of their packages and started to blend less expensive Robusta coffee into the mix. To avoid making larger changes to the visual design of the package the Arabica label was replaced by other labeling, keeping the previous ornamental design, thereby presenting a case of shrinkflation . In some case,

1044-549: A student of Balliol College from Crete named Nathaniel Conopios of Crete. Oxford's Queen's Lane Coffee House , established in 1654, is still in existence today. Coffee was introduced in France in 1657 and in Austria and Poland after the 1683 Battle of Vienna , when coffee was captured from supplies of the defeated Turks. When coffee reached North America during the Colonial period, it

1131-428: A third are beetles , and over a quarter are bugs . Some 20 species of nematodes , 9 species of mites, and several snails and slugs also attack the crop. Birds and rodents sometimes eat coffee berries, but their impact is minor compared to invertebrates. In general, arabica is the more sensitive species to invertebrate predation overall. Each part of the coffee plant is assailed by different animals. Nematodes attack

1218-517: 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. It has the highest sales in the world market for hot drinks. Coffee production begins when the seeds of the Coffea plant's fruits (coffee cherries) are separated to produce unroasted green coffee beans . The beans are roasted and then ground into fine particles. Coffee

1305-419: 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

1392-546: Is estimated between 1.08 million and 543,000 years ago and is linked to changing environmental conditions in East Africa. Wild plants grow between 9 and 12 m (30 and 39 ft) tall, and have an open branching system; the leaves are opposite, simple elliptic-ovate to oblong, 6–12 cm (2.5–4.5 in) long and 4–8 cm (1.5–3 in) broad, glossy dark green. The flowers are white, 10–15 mm in diameter, and grow in axillary clusters. The seeds are contained in

1479-475: Is generally in places where the humidity is very high. An Asian coffee known as kopi luwak undergoes a peculiar process made from coffee berries eaten by the Asian palm civet , passing through its digestive tract, with the beans eventually harvested from feces . Coffee brewed from this process is among the most expensive in the world, with bean prices reaching $ 160 per pound or $ 30 per brewed cup. Kopi luwak coffee

1566-536: Is induced by the fungal pathogen Gibberella xylarioides . It can affect several Coffea species, and could potentially threaten production worldwide. Mycena citricolor , American leaf spot, is a fungus that can affect the whole coffee plant. It grows on leaves, resulting in leaves with holes that often fall from the plant. It is a threat primarily in Latin America. Over 900 species of insect have been recorded as pests of coffee crops worldwide. Of these, over

1653-661: 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. The two most commonly grown coffee bean types are C. arabica and C. robusta . Coffee plants are cultivated in over 70 countries , primarily in

1740-403: Is often simpler and less labor-intensive, and a wet process method, which incorporates batch fermentation, uses larger amounts of water in the process, and often yields a milder coffee. Then they are sorted by ripeness and color, and most often the flesh of the berry is removed, usually by machine, and the seeds are fermented to remove the slimy layer of mucilage still present on the seed. When

1827-609: Is prevented by pruning the tree. The flowers only last a few days, leaving behind only the thick, dark-green leaves. The berries then begin to appear. These are as dark green as the foliage until they begin to ripen, at first to yellow and then light red and finally darkening to a glossy, deep red. At this point, they are called " cherries ", which fruit they then resemble, and are ready for picking. The berries are oblong and about 1 cm long. Inferior coffee results from picking them too early or too late, so many are picked by hand to be able to better select them, as they do not all ripen at

1914-414: Is said to have a uniquely rich, slightly smoky aroma and flavor with hints of chocolate, resulting from the action of digestive enzymes breaking down bean proteins to facilitate partial fermentation . In Thailand, black ivory coffee beans are fed to elephants whose digestive enzymes reduce the bitter taste of beans collected from dung. These beans sell for up to $ 1,100 a kilogram ($ 500 per lb), achieving

2001-399: Is to raise seedlings in nurseries that are then planted outside after six to twelve months. Coffee is often intercropped with food crops, such as corn, beans, or rice during the first few years of cultivation as farmers become familiar with its requirements. Coffee plants grow within a defined area between the tropics of Cancer and Capricorn, termed the bean belt or coffee belt. In 2020,

2088-413: Is used as an inexpensive substitute for arabica in many commercial coffee blends. Good quality robusta beans are used in traditional Italian espresso blends to provide a full-bodied taste and a better foam head (known as crema ). Additionally, robusta is less susceptible to disease than arabica and can be cultivated in lower altitudes and warmer climates where arabica does not thrive. The robusta strain

2175-466: Is vulnerable, hastened the uptake of the resistant robusta. The pathogen and results in light, rust-colored spots on the undersides of coffee plant leaves. It grows exclusively on the leaves of coffee plants. Coffee leaf rust is found in virtually all countries that produce coffee. Beans from different countries or regions can usually be distinguished by differences in flavor, aroma, body, and acidity. These taste characteristics are dependent not only on

2262-560: The Boma Plateau in South Sudan . Coffea arabica is also found on Mount Marsabit in northern Kenya , but it is unclear whether this is a truly native or naturalised occurrence; recent studies support it being naturalised. The species is widely naturalised in areas outside its native land, in many parts of Africa , Latin America , Southeast Asia , India , China , and assorted islands in

2349-601: The Caribbean and in the Pacific . The coffee tree was first brought to Hawaii in 1813, and it began to be extensively grown by about 1850. It was formerly more widely grown, especially in Kona , and it persists after cultivation in many areas. In some valleys, it is a highly invasive weed. In the Udawattakele and Gannoruwa Forest Reserves near Kandy, Sri Lanka, coffee shrubs are also

2436-516: The Central Statistical Agency in 2005, this woreda has an estimated total population of 260,193, of whom 131,922 are men and 128,271 women; 70,675 or 27.16% of its population are urban dwellers, which is greater than the Zone average of 12.3%. With an estimated area of 1,588.13 square kilometers, Ambo has an estimated population density of 163.8 people per square kilometer, which is greater than

2523-545: The Rainforest Alliance have led a campaign for 'shade-grown' and organic coffees , which can be sustainably harvested. Shaded coffee cultivation systems show greater biodiversity than full-sun systems, and those more distant from continuous forest compare rather poorly to undisturbed native forest in terms of habitat value for some bird species. Coffee production uses a large volume of water. On average it takes about 140 litres (37  US gal ) of water to grow

2610-682: The coffee industry have also pointed to its negative impact on the environment and the clearing of land for coffee-growing and water use. The word coffee entered the English language in 1582 via the Dutch koffie , borrowed from the Ottoman Turkish kahve ( قهوه ), borrowed in turn from the Arabic qahwah ( قَهْوَة ). Medieval Arab lexicographers traditionally held that the etymology of qahwah meant 'wine', given its distinctly dark color, and

2697-426: The polyploid species of the genus Coffea , as it carries 4 copies of the 11 chromosomes (44 total) instead of the 2 copies of diploid species. Specifically, Coffea arabica is itself the result of a hybridization between the diploids Coffea canephora and Coffea eugenioides , thus making it an allotetraploid , with two copies of two different genomes. This hybridization event at the origin of Coffea arabica

2784-685: The 18th century, coffee consumption declined in Britain, giving way to tea drinking. Tea was simpler to make, and had become cheaper with the British conquest of India and the tea industry there. During the Age of Sail, seamen aboard ships of the British Royal Navy made substitute coffee by dissolving burnt bread in hot water. The Frenchman Gabriel de Clieu took a coffee plant to the French territory of Martinique in

2871-518: The 19th and 20th centuries. Rapid growth in coffee production in South America during the second half of the 19th century was matched by an increase in consumption in developed countries, though nowhere has this growth been as pronounced as in the United States, where a high rate of population growth was compounded by doubling of per capita consumption between 1860 and 1920. Though the United States

2958-694: The 19th century. After that, much of the Ethiopian coffee was exported to Aden via Berbera. By the 16th century, coffee had reached the rest of the Middle East and North Africa. The first coffee seeds were smuggled out of the Middle East by Sufi Baba Budan from Yemen to India during the time. Before then, all exported coffee was boiled or otherwise sterilized. Portraits of Baba Budan depict him as having smuggled seven coffee seeds by strapping them to his chest. The first plants from these smuggled seeds were planted in Mysore . Coffee had spread to Italy by 1600 and then to

3045-855: The Caribbean in the 1720s, from which much of the world's cultivated arabica coffee is descended. Coffee thrived in the climate and was conveyed across the Americas. Coffee was cultivated in Saint-Domingue (now Haiti) from 1734, and by 1788 it supplied half the world's coffee. The conditions that the enslaved people worked in on coffee plantations were a factor in the soon to follow Haitian Revolution . The coffee industry never fully recovered there. Meanwhile, coffee had been introduced to Brazil in 1727, although its cultivation did not gather momentum until independence in 1822. After this time, massive tracts of rainforest were cleared for coffee plantations, first in

3132-473: The Coffee Community). Coffee berries are traditionally selectively picked by hand, which is labor-intensive as it involves the selection of only the berries at the peak of ripeness. More commonly, crops are strip picked, where all berries are harvested simultaneously regardless of ripeness by person or machine. After picking, green coffee is processed by one of two types of method—a dry process method which

Although etymologists have connected it with a word meaning ' wine ' , it is also thought to be from the Kaffa region of Ethiopia. The terms coffee pot and coffee break originated in 1705 and 1952, respectively. There are multiple anecdotal origin stories which lack evidence. In a commonly repeated legend, Kaldi ,

The 2007 national census reported this woreda's total population as 108,406, of whom 54,186 were men and 54,220 women; 865 or 0.8% of its population were urban dwellers. The majority of the inhabitants (51.82%) said they practised Ethiopian Orthodox Christianity , while 32% of the population practiced traditional religions, and 15.9% were Protestant . Based on figures published by

One account credits Muhammad Ibn Sa'd for bringing the beverage to Aden from the African coast, other early accounts say Ali ben Omar of the Shadhili Sufi order was the first to introduce coffee to Arabia. 16th-century Islamic scholar Ibn Hajar al-Haytami notes in his writings that a beverage called qahwa developed from a tree in the Zeila region located in the Horn of Africa. Coffee

The 1994 national census reported a total population for this woreda of 177,465, of whom 87,325 were men and 90,140 women; 39,535 or 22.28% of its population were urban dwellers at the time. The two largest ethnic groups reported in Ambo were the Oromo (92.58%), and the Amhara (5.76%); all other ethnic groups made up 1.16% of the population. Oromiffa was spoken as

3567-418: The beans. The coffee beans are actually two seeds within the fruit; sometimes, a third seed or one seed, a peaberry , grows in the fruit at the tips of the branches. These seeds are covered in two membranes; the outer one is called the "parchment coat" and the inner one is called the "silver skin". On Java , trees are planted at all times of the year and are harvested year-round. In parts of Brazil , however,

3654-505: The berries have only one; these are called peaberries . Arabica berries ripen in six to eight months, while robusta takes nine to eleven months. Coffea arabica is predominantly self-pollinating, and as a result, the seedlings are generally uniform and vary little from their parents. In contrast, Coffea canephora , and C. liberica are self-incompatible and require outcrossing . This means that useful forms and hybrids must be propagated vegetatively . Cuttings, grafting, and budding are

Unshaded coffee plants grown with fertilizer yield the most coffee, although unfertilized shaded crops generally yield more than unfertilized unshaded crops: the response to fertilizer is much greater in full sun. While traditional coffee production causes berries to ripen more slowly and produce lower yields,

3828-452: The coffee beans needed to produce one cup of coffee. Growing the plants needed to produce 1 kg (2.2 lb) of roasted coffee in Africa, South America or Asia requires 26,400 litres (7,000  US gal ) of water. As with many other forms of agriculture, often much of this is rainwater, much of which would otherwise run off into rivers or coastlines, while much water actually absorbed by

3915-412: The coffee growing on plantations around the world contains less than 1% of the diversity in the wilds of Yemen alone. Climate change also serves as a threat to cultivated C. arabica due to their temperature sensitivity, and some studies estimate that by 2050, over half of the land used for cultivating coffee could be unproductive. The more heat-tolerant Coffea stenophylla may replace C. arabica as

4002-478: The coffee is still advertised as "100% Arabica" in flyers in 2024, but is no longer declared so on the actual package. One strain of Coffea arabica (called AC1, AC2 and AC3 in honour of the geneticist Alcides Carvalho) naturally contains very little caffeine. While beans of normal C. arabica plants contain 12 mg of caffeine per gram of dry mass, these mutants contain only 0.76 mg of caffeine per gram, with similar expected cup quality. Although it has

Varietals are generally known by the region in which they are grown, such as Colombian , Java , and Kona . Arabica coffee beans are cultivated mainly in Latin America, eastern Africa or Asia, while robusta beans are grown in central Africa, southeast Asia, and Brazil. Coffee can also be blended with medicinal or functional mushrooms, of which some of

Most African coffee is dried in this manner and certain coffee farms around the world are starting to use this traditional method. Next, the coffee is sorted, and labeled as green coffee. Some companies use cylinders to pump in heated air to dry the coffee seeds, though this

4263-556: The color of the bean. Coffea arabica Coffea arabica ( / ə ˈ r æ b ɪ k ə / ), also known as the Arabica coffee , is a species of flowering plant in the coffee and madder family Rubiaceae . It is believed to be the first species of coffee to have been cultivated and is the dominant cultivar, representing about 60% of global production. Coffee produced from the less acidic, more bitter, and more highly caffeinated robusta bean ( C. canephora ) makes up most of

4350-551: The equatorial regions of the Americas, Southeast Asia, the Indian subcontinent, and Africa. Green, unroasted coffee is traded as an agricultural commodity. The global coffee industry is massive and worth $ 495.50 billion as of 2023. In the same year, Brazil was the leading grower of coffee beans, producing 35% of the world's total, followed by Vietnam and Colombia. While coffee sales reach billions of dollars annually worldwide, coffee farmers disproportionately live in poverty. Critics of

4437-412: The fermentation is finished, the seeds are washed with large quantities of fresh water to remove the fermentation residue, which generates massive amounts of coffee wastewater . Finally, the seeds are dried. The best (but least used) method of drying coffee is using drying tables. In this method, the pulped and fermented coffee is spread thinly on raised beds, which allows the air to pass on all sides of

4524-472: The flavor. There are also various coffee substitutes . 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

4611-486: The genetic variation of C. arabica relies on conserving healthy populations of wild coffee in the Afromontane rainforests of Yemen. Genetic research has shown coffee cultivation is threatening the genetic integrity of wild coffee because it exposes wild genotypes to cultivars . Nearly all of the coffee that has been cultivated over the past few centuries originated from just a handful of wild plants from Yemen, and

4698-409: The ground, which causes scale parasites to not only attack the scale on the fallen branches but in the plant as well. The 2-mm-long coffee borer beetle ( Hypothenemus hampei ) is the most damaging insect pest of the world's coffee industry, destroying up to 50 percent or more of the coffee berries on plantations in most coffee-producing countries. The adult female beetle nibbles a single tiny hole in

4785-774: The large family Rubiaceae . They are evergreen shrubs or trees that may grow 5 m (15 ft) tall when unpruned. The leaves are dark green and glossy, usually 10–15 cm (4–6 in) long and 6 cm (2.4 in) wide, simple, entire, and opposite. Petioles of opposite leaves fuse at the base to form interpetiolar stipules , characteristic of Rubiaceae . The flowers are axillary , and clusters of fragrant white flowers bloom simultaneously. Gynoecium consists of an inferior ovary, also characteristic of Rubiaceae. The flowers are followed by oval berries of about 1.5 cm (0.6 in). When immature, they are green, and they ripen to yellow, then crimson, before turning black on drying. Each berry usually contains two seeds, but 5–10% of

Harsh conditions led to many uprisings, coups, and bloody suppression of peasants. The notable exception was Costa Rica, where lack of ready labor prevented the formation of large farms. Smaller farms and more egalitarian conditions ameliorated unrest over

4959-405: The middle of the 15th century in the accounts of Ahmed al-Ghaffar in Yemen, where coffee seeds were first roasted and brewed in a similar way to how it is prepared now. Coffee was used by Sufi circles to stay awake for their religious rituals. Accounts differ on the origin of the coffee plant before its appearance in Yemen. From Ethiopia, coffee could have been introduced to Yemen via trade across

5046-480: The molecular level and are close to commercialization. Of the two main species grown, arabica coffee (from C. arabica ) is generally more highly regarded than robusta coffee (from C. canephora ). Robusta coffee tends to be bitter and has less flavor but a better body than arabica. For these reasons, about three-quarters of coffee cultivated worldwide is C. arabica . Robusta strains also contain about 40–50% more caffeine than arabica. Consequently, this species

5133-526: The most frequently used include: lion's mane, chaga, cordyceps and reishi. Mushroom coffee has about half the caffeine of standard coffee. However, drinking mushroom coffee can result in digestive issues and high amounts can result in liver toxicity. There is little clinical evidence for the benefits of mushroom coffee. Coffee wilt disease or tracheomycosis is a common vascular wilt found in Eastern and Central Africa that can kill coffee trees it infects. It

5220-427: The most highly regarded species, is native to the southwestern highlands of Ethiopia and the Boma Plateau in southeastern Sudan and Mount Marsabit in northern Kenya. C. canephora is native to western and central Subsaharan Africa, from Guinea to Uganda and southern Sudan. Less popular species are C. liberica , C. stenophylla , C. mauritiana , and C. racemosa . All coffee plants are classified in

5307-427: The nitrogen-fixing non-legume sheoaks of the genus Casuarina , and the silky oak Grevillea robusta . This method is commonly called " shade-grown coffee ". Starting in the 1970s, many farmers switched their production method to sun cultivation, in which coffee is grown in rows under full sun with little or no forest canopy. This causes berries to ripen more rapidly and bushes to produce higher yields, but requires

5394-474: The number of coffee berry borers in Costa Rica coffee plantations. Originally, coffee was grown in the shade of trees that provided a habitat for many animals and insects. Remnant forest trees were used for this purpose, but many species have been planted as well. These include leguminous trees of the genera Acacia , Albizia , Cassia , Erythrina , Gliricidia , Inga , and Leucaena , as well as

Coffee is often grown in countries where there is a water shortage, such as Ethiopia . Used coffee grounds may be used for composting or as

5568-406: The primary export and economic backbone for African countries like Uganda, Burundi, Rwanda, and Ethiopia, as well as many Central American countries. Several species of shrub of the genus Coffea produce the berries from which coffee is extracted. The two main species commercially cultivated are Coffea canephora (predominantly a form known as 'robusta') and C. arabica . C. arabica ,

5655-479: The quality of the coffee is allegedly superior. In addition, the traditional shaded method provides living space for many wildlife species. Proponents of shade cultivation say environmental problems such as deforestation, pesticide pollution, habitat destruction, and soil and water degradation are the side effects of the practices employed in sun cultivation. The American Birding Association , Smithsonian Migratory Bird Center , National Arbor Day Foundation , and

5742-463: The remaining coffee production. The natural populations of Coffea arabica are restricted to the forests of South Ethiopia and Yemen. Coffea arabica was first described scientifically by Antoine de Jussieu , who named it Jasminum arabicum after studying a specimen from the Botanic Gardens of Amsterdam . Linnaeus placed it in its own genus Coffea in 1737. Coffea arabica is one of

5829-457: The rest of Europe, Indonesia, and the Americas. In 1583, Leonhard Rauwolf , a German physician, gave this description of coffee after returning from a ten-year trip to the Near East: A beverage as black as ink, useful against numerous illnesses, particularly those of the stomach. Its consumers take it in the morning, quite frankly, in a porcelain cup passed around and from which each one drinks

5916-542: The roots, coffee borer beetles burrow into stems and woody material, and the foliage is attacked by over 100 species of larvae (caterpillars) of butterflies and moths. Mass spraying of insecticides has often proven disastrous, as predators of the pests are more sensitive than the pests themselves. Instead, integrated pest management has developed, using techniques such as targeted treatment of pest outbreaks, and managing crop environment away from conditions favoring pests. Branches infested with scale are often cut and left on

The trees are difficult to cultivate and each tree can produce from 0.5 to 5.0 kilograms (1.1 to 11.0 lb) of dried beans, depending on the tree's individual character and the climate that season. The most valuable part of this cash crop is the beans inside. Each berry holds two locules containing

6090-465: The spread of Yemen's trade. Indonesian coffees, such as Sumatran and Java, are known for their heavy body and low acidity. This makes them ideal for blending with the higher acidity coffees from Central America and East Africa . Coffea arabica accounts for 60% of the world's coffee production. C. arabica takes approximately seven years to mature fully, and it does best with 1.0–1.5 metres (39–59 in) of rain, evenly distributed throughout

6177-413: The story is likely apocryphal. Another legend attributes the discovery of coffee to a Sheikh Omar. Starving after being exiled from Mokha (a port city in what is now Yemen), Omar found berries. After attempting to chew and roast them, Omar boiled them, which yielded a liquid that revitalized and sustained him. The earliest credible evidence of coffee drinking or knowledge of the coffee tree appears in

6264-480: The sustainability of arabica coffee production, leading to attempts to breed new cultivars for the changing conditions. Gourmet coffees are almost exclusively high-quality mild varieties of arabica coffee, and among the best known arabica coffee beans in the world are those from Jamaican Blue Mountain , Colombian Supremo , Tarrazú , Costa Rica , Guatemalan Antigua , and Ethiopian Sidamo . Blends consisting only of Arabica are often labelled "100% Arabica" as

6351-419: The sweet smell of jasmine flowers. Flowers opening on sunny days result in the greatest number of berries. This can be problematic and deleterious, however, as coffee plants tend to produce too many berries; this can lead to an inferior harvest and even damage yield in the following years, as the plant will favor the ripening of berries to the detriment of its own health. On well-kept plantations, overflowering

6438-665: The taste of the beverage by changing the coffee bean both physically and chemically. The bean decreases in weight as moisture is lost and increases in volume, causing it to become less dense. The density of the bean also influences the strength of the coffee and the requirements for packaging. The actual roasting begins when the temperature inside the bean reaches approximately 200 °C (392 °F), though different varieties of seeds differ in moisture and density and therefore roast at different rates. During roasting, caramelization occurs as intense heat breaks down starches , changing them to simple sugars that begin to brown, which darkens

6525-484: The trees have a season and are harvested only in winter. The plants are vulnerable to damage in such poor growing conditions as cold or low pH soil , and they are also more vulnerable to pests than the C. robusta plant. It is expected that a medium-term depletion of indigenous populations of C. arabica may occur, due to projected global warming , based on IPCC modelling. Climate change—rising temperatures, longer droughts, and excessive rainfall—appears to threaten

6612-452: The usual methods of vegetative propagation. On the other hand, there is great scope for experimentation in search of potential new strains. The traditional method of planting coffee is to place 20 seeds in each hole at the beginning of the rainy season . This method loses about 50% of the seeds' potential, as about half fail to sprout. A more effective process of growing coffee, used in Brazil,

6699-517: The vicinity of Rio de Janeiro and later São Paulo. Brazil went from having essentially no coffee exports in 1800 to being a significant regional producer in 1830, to being the largest producer in the world by 1852. In 1910–1920, Brazil exported around 70% of the world's coffee, Colombia, Guatemala, and Venezuela exported 15%, and Old World production accounted for less than 5% of world exports. Many countries in Central America took up cultivation in

6786-424: The world production of green coffee beans was 175,647,000 60 kg bags, led by Brazil with 39% of the total, followed by Vietnam, Colombia, and Indonesia. Brazil is the largest coffee exporting nation, accounting for 15% of all world exports in 2019. As of 2021, no synthetic coffee products are publicly available but multiple bioeconomy companies have reportedly produced first batches that are highly similar on

6873-409: The world's most expensive coffee, three times costlier than palm civet coffee beans. The next step in the process is the roasting of green coffee. Coffee is usually sold in a roasted state, and with rare exceptions, such as infusions from green coffee beans, coffee is roasted before it is consumed. It can be sold roasted by the supplier, or it can be home roasted . The roasting process influences

6960-702: The year. It is usually cultivated at an altitude between 1,300 and 1,500 m (4,300 and 4,900 ft), but there are plantations that grow it as low as sea level and as high as 2,800 m (9,200 ft). The plant can tolerate low temperatures, but not frost, and it does best with an average temperature between 15 and 24 °C (59 and 75 °F). Commercial cultivars mostly only grow to about 5 m, and are frequently trimmed as low as 2 m to facilitate harvesting. Unlike Coffea canephora , C. arabica prefers to be grown in light shade. Two to four years after planting, C. arabica produces small, white, highly fragrant flowers. The sweet fragrance resembles

7047-467: Was derived from the verb qahiya ( قَهِيَ ), ' to have no appetite '. The word qahwah most likely meant 'the dark one', referring to the brew or the bean; qahwah is not the name of the bean, which are known in Arabic as bunn and in Cushitic languages as būn . Semitic languages have the root qhh , 'dark color', which became a natural designation for the beverage. Its cognates include

7134-716: Was first collected in 1890 from the Lomani River , a tributary of the Congo River, and was conveyed from the Congo Free State (now the Democratic Republic of the Congo) to Brussels to Java around 1900. From Java, further breeding resulted in the establishment of robusta plantations in many countries. In particular, the spread of the devastating coffee leaf rust (caused by the fungal pathogen Hemileia vastatrix ), to which arabica

7221-526: Was first exported from Ethiopia to Yemen by Somali merchants from Berbera and Zeila in modern-day Somaliland, which was procured from Harar and the Abyssinian interior. According to Captain Haines, who was the colonial administrator of Aden (1839–1854), Mokha historically imported up to two-thirds of its coffee from Berbera-based merchants before the coffee trade of Mokha was captured by British-controlled Aden in

7308-545: Was initially not as successful as in Europe, as alcoholic beverages remained more popular. During the Revolutionary War, the demand for coffee increased so much that dealers had to hoard their scarce supplies and raise prices dramatically; this was also due to the reduced availability of tea from British merchants, and a general resolution among many Americans to avoid drinking tea following the 1773 Boston Tea Party . During

7395-646: Was not the heaviest coffee-drinking nation at the time (Belgium, the Netherlands and Nordic countries all had comparable or higher levels of per capita consumption), due to its sheer size, it was already the largest consumer of coffee in the world by 1860, and, by 1920, around half of all coffee produced worldwide was consumed in the US. Coffee has become a vital cash crop for many developing countries. Over one hundred million people in developing countries have become dependent on coffee as their primary source of income. It has become

7482-576: Was the first to import coffee on a large scale. The Dutch later grew the crop in Java and Ceylon. The first exports of Indonesian coffee from Java to the Netherlands occurred in 1711. Through the efforts of the British East India Company , coffee also became popular in England. In a diary entry of May 1637, John Evelyn recorded tasting the drink at Oxford in England, where it had been brought by

7569-630: Was useful in prolonging their working hours. The Arab innovation in Yemen of making a brew from roasted beans spread first among the Egyptians and Turks , and later on found its way around the world. Other scholars believe that the coffee plant was introduced from Yemen, based on a Yemeni tradition that slips of both coffee and qat were planted at Udein ('the two twigs') in Yemen in pre-Islamic times. Arabica coffee production in Indonesia began in 1699 through
