Coffea Arabica is descended from the original coffee trees discovered in Ethiopia. These trees produce a fine, mild, aromatic coffee and represent approximately 70% of the world’s coffee production. The beans are flatter and more elongated than Robusta and contain lower levels of caffeine.
On the world market, Arabica coffees bring the highest prices. The better Arabicas are high grown coffees — generally grown between 2,000 to 6,000 feet (610 to 1830 meters) above sea level — though optimal altitude varies with proximity to the equator.
The most important factor is that temperatures must remain mild, ideally between 59 – 75 degrees Fahrenheit, with about 60 inches of rainfall a year. The trees are hearty, but a heavy frost will kill them. Arabica trees are costly to cultivate because the ideal terrain tends to be steep and access is difficult. Also, because the trees are more disease-prone than Robusta, they require additional care and attention.
