Arabica coffee

Coffea arabica

Also calledBunn (Arabic) · Qahwa (Arabic, the drink) · Buna (Amharic) · Kahve (Turkish) · Kāfēi (Chinese) · Kahawa (Swahili) · Café (Spanish/Portuguese)

An evergreen shrub of Ethiopia's highland forests whose roasted seeds make about 60% of the world's coffee. A natural hybrid of two wild species, it is unusual in its genus for being self-fertile, and wild populations are Endangered by deforestation and climate change.

Coffea arabica, 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 makes up most of the remaining coffee production. The natural populations of Coffea arabica are restricted to the forests of South Ethiopia, South Sudan, and Yemen. Wikipedia

What it can do

  1. iAllotetraploid hybrid of Coffea canephora and Coffea eugenioides
  2. iiSelf-pollinating, unlike almost all other Coffea species
  3. iiiCaffeine in seeds and leaves deters insects and inhibits competing seedlings
  4. ivJasmine-scented white flowers open all at once after the first rains

Eatenseeds (roasted, brewed) · fruit pulp (cascara tea) · leaves (brewed as tea in Ethiopia and Sumatra)

Beans, cherry husk and leaves are used for drinks. Caffeine overdose from concentrated products can be dangerous.

In the medicine cabinet

TraditionUse
Sufi devotional practice (Yemen)Coffee drunk to stay awake during night prayers in the 15th century
Modern medicineCaffeine is an approved drug, used with analgesics for headache and for apnoea in premature infants
Ethiopian folk medicineCoffee leaves and husks brewed with butter or salt as a tonic

Weight of evidence

Strong. An approved drug, or consistent results in well-run clinical trials.

Active compounds

caffeine, chlorogenic acids, trigonelline, cafestol, kahweol

CautionCaffeine can cause insomnia, anxiety and palpitations; limit in pregnancy. Unfiltered coffee raises LDL cholesterol via cafestol.

Fruit

Drupe ('cherry')

Ripens: Varies by region; 6–9 months after flowering

Oval cherry 1–1.5 cm, green ripening to bright red or yellow, with thin sweet pulp around two seeds back to back.

Seed: Roasted coffee beans

Seed

8–12 mm

Pale greenish-grey to bluish 'green beans', oval, about 1 cm long, flat on one face with a central S-shaped groove, domed on the other; covered by a papery parchment and a silver skin. A single round seed ('peaberry') forms in some cherries

Dispersal
Birds and mammals eat the cherries
Germination
Remove pulp, sow fresh seed in parchment 1 cm deep at 25–30 °C in shade; slow, 6–10 weeks

USDA 10–12; best in frost-free tropical highlands (900–2,000 m). Survives winters down to about -1 °C.

Light
Partial shade; tolerates sun with ample water
Water
Moderate–high, with a short dry season to trigger flowering
Soil
Deep, well-drained, slightly acidic (pH 5–6.5), rich volcanic or forest loam
Propagation
Seed (comes reasonably true because self-pollinating); cuttings of selected lines
To harvest
3–4 years to first crop
Climates
Tropical highland, Subtropical
  1. 1Sow fresh seed of a named variety (e.g. 'Typica', 'Bourbon', or rust-resistant 'Castillo') in shaded nursery bags.
  2. 2Transplant at 6–12 months, 2–2.5 m apart, under light shade trees that also protect against wind.
  3. 3Mulch, feed with compost, and water during dry spells, while allowing a short dry spell before the main rains to induce mass flowering.
  4. 4Prune to control height (1.5–2 m) and remove old unproductive stems periodically; watch for coffee leaf rust.
  5. 5Hand-pick only fully red cherries; process by washing and fermenting or by sun-drying whole cherries.

Marginalia

Ethiopian legend credits the goatherd Kaldi with noticing his goats dancing after eating coffee cherries. Coffee houses spread from Yemen to Mecca, Cairo and Istanbul by the 16th century, and Ottoman authorities repeatedly tried to ban them as places of sedition.

Curiosity

The Typica coffee of much of the Caribbean and Latin America traces to a few plants: one given to Louis XIV in 1714 was the source of seedlings Gabriel de Clieu carried to Martinique around 1720, sharing his water ration with it on the voyage.
