Coffea arabica, Linn. Common or Ababian Coffee. Fig. 1024. Lvs. 3-6 in. long, rather thin, oblong, nearly 3 times as long as broad, more or less abruptly contracted near the apex to a point about ½in. long: segms. of corolla over twice as long as wide: fr. a 2-seeded, deep crimson berry, but the “berries” or beans of commerce are the seeds. The commercial varieties of coffee are based largely on the size, shape, color and flavor of the seeds, and hence the fr. is very variable, but the typical fr. may be considered to be oval and ½in- long. Indigenous in Abyssinia, Mozambique and Angola; supposed to have been intro. in early Mohammedan times from Abyssinia to Arabia, whence it became known to Europeans in the 16th century. This species furnished until recently the entire commercial product. B.M. 1303. Gng. 6:55.—A variegated form,var. variegata, Hort., is more showy than the type. It is offered by dealers in tropical plants. As coffee grows wild in Afr. it is a small tree 10-15 ft. high, with the trunk 9-12 in. thick at the base. Often cult, under glass in the N. for its economic interest, and in S. Calif, it is a good outdoor ornamental shrub, esteemed for its shining lvs., fragrant white fls., and red berries.

'''''Coffea arabica''''' ({{IPAc-en|icon|ə|ˈ|r|æ|b|ɪ|k|ə}}) is a species of ''[[Coffea]]'' originally indigenous to the mountains of [[Yemen]] in the [[Arabian Peninsula]], hence its name, and also from the southwestern highlands of [[Ethiopia]] and southeastern [[Sudan]]. It is also known as the "coffee shrub of Arabia", "mountain coffee" or "arabica coffee". ''Coffea arabica'' is believed to be the first species of coffee to be cultivated, being grown in southwest [[Arabia]] for well over 1,000 years. It is said to produce better coffee than the other major commercially grown coffee species, ''[[Coffea canephora]] (robusta)'', but tastes vary. ''C. arabica'' contains less [[caffeine]] than any other commercially cultivated species of coffee. Wild plants grow to between 9 and 12 m tall, and have an open branching system; the [[leaf|leaves]] are opposite, simple elliptic-ovate to oblong, 6–12 cm long and 4–8 cm broad, glossy dark green. The [[flower]]s are white, 10–15 mm in diameter and grow in axillary clusters. The [[fruit]] is a [[drupe]] (though commonly called a "berry") 10–15 mm in diameter, maturing bright red to purple and typically contains two [[seed]]s (the coffee 'bean').

Two to four years after planting, ''C. arabica'' produces small, white and highly fragrant flowers. The sweet fragrance resembles the sweet smell of [[jasmine]] flowers. When flowers open on sunny days, this results in the greatest numbers of berries. This can be a curse, 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 favour the ripening of berries to the detriment of its own health. On well kept plantations, this is prevented by pruning the tree. The flowers themselves 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' 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 the same time. They are sometimes shaken off the tree onto mats, which means that ripe and unripe berries are collected together.

According to [[legend]], human cultivation of coffee began after [[goat]]s in [[Ethiopia]] were seen becoming frisky after eating the leaves and fruits of the coffee tree. In reality, human consumption of coffee [[fruits]] probably began long before humans took up [[pastoralism]]. In Ethiopia there are still some locales where people drink a [[tisane]] made from the leaves of the coffee tree.
 
  
The first written record of coffee, made from [[roasted]] coffee beans, comes from [[Arab]]ian scholars who wrote that it was useful in prolonging their working hours. The Arab innovation of making a brew from roasted beans, spread first among the Egyptians and [[Turkic peoples|Turks]] and later on found its way around the world.

Brazilian biologists have found an Ethiopian ''Coffea arabica'' that naturally contains very little caffeine. [[Paulo Mazzafera]], a researcher of [[Universidade Estadual de Campinas]], recently published findings in the journal ''[[Nature (journal)|Nature]]'' about these strains of ''Coffea arabica'' plants. While beans of normal ''Coffea arabica'' plants contains 12 milligrams of caffeine per gram of dry mass, these newly found mutants contain only 0.76 milligrams of caffeine per gram with all the taste of normal coffee.

Coffea arabica (Template:IPAc-en) is a species of Coffea originally indigenous to the mountains of Yemen in the Arabian Peninsula, hence its name, and also from the southwestern highlands of Ethiopia and southeastern Sudan. It is also known as the "coffee shrub of Arabia", "mountain coffee" or "arabica coffee". Coffea arabica is believed to be the first species of coffee to be cultivated, being grown in southwest Arabia for well over 1,000 years. It is said to produce better coffee than the other major commercially grown coffee species, Coffea canephora (robusta), but tastes vary. C. arabica contains less caffeine than any other commercially cultivated species of coffee. Wild plants grow to between 9 and 12 m tall, and have an open branching system; the leaves are opposite, simple elliptic-ovate to oblong, 6–12 cm long and 4–8 cm broad, glossy dark green. The flowers are white, 10–15 mm in diameter and grow in axillary clusters. The fruit is a drupe (though commonly called a "berry") 10–15 mm in diameter, maturing bright red to purple and typically contains two seeds (the coffee 'bean').

Cultivation

C. arabica takes about seven years to mature fully, and does best with 1.0–1.5 meters (about 40–59 inches) of rain, evenly distributed throughout the year.[citation needed] It is usually cultivated between 1,300 and 1,500 m altitude, but there are plantations as low as sea level and as high as 2,800 m.[citation needed] The plant can tolerate low temperatures, but not frost, and it does best when the temperature hovers around 20 °C °F .[citation needed] 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.[citation needed]

Drawing of Coffea arabica

Two to four years after planting, C. arabica produces small, white and highly fragrant flowers. The sweet fragrance resembles the sweet smell of jasmine flowers. When flowers open on sunny days, this results in the greatest numbers of berries. This can be a curse, 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 favour the ripening of berries to the detriment of its own health. On well kept plantations, this is prevented by pruning the tree. The flowers themselves 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' 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 the same time. They are sometimes shaken off the tree onto mats, which means that ripe and unripe berries are collected together.

The trees are difficult to cultivate and each tree can produce anywhere from 0.5–5.0 kg of dried beans, depending on the tree's individual character and the climate that season. The real prize of this cash crop are the beans inside. Each berry holds two locules containing the beans. The coffee beans are actually two seeds within the fruit, there is sometimes a third seed or one seed, a peaberry in the fruits at 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 Island, trees are planted at all times of the year and are harvested year round. In parts of Brazil, however, the trees have a season and are harvested only in winter. The plants are vulnerable to damage in poor growing conditions (cold, low pH soil) and are also more vulnerable to pests than the C. robusta plant.[1] Gourmet coffees are almost exclusively high-quality mild varieties of arabica coffee, such as Colombian coffee.
