Coffee species
Arabica
The most widely grown coffee species, generally associated with more acidity and a wider flavour range than robusta. Accounts for the majority of speciality coffee production.
Where it comes from
Arabica is native to the highland forests of south-western Ethiopia and neighbouring South Sudan, where it still grows wild as an understorey tree. It is unusual among coffee species in being a natural hybrid: it arose from a cross between two other species, Coffea canephora — robusta — and Coffea eugenioides, and it carries a full set of chromosomes from each: 44 in all, where each parent species has 22. That single origin, followed by the handful of plants carried out through Yemen to found the world's plantations, left cultivated arabica with very little genetic variety. Most of the arabica grown outside Ethiopia descends from two lineages, Typica and Bourbon.

Measured data
| Species | Production |
|---|---|
| Arabica | 94.4 million bags |
| Robusta | 84.4 million bags |
Source: USDA Foreign Agricultural Service, Coffee: World Markets and Trade, July 2026 circular. Period: Marketing year 2025/26. Estimate, as published in July 2026. One bag is 60 kg of green coffee. Other species, including liberica and excelsa, are not reported separately.
How it grows
Arabica is a plant of cool tropical mountains. It wants mild, stable temperatures without frost, which in the tropics means altitude, and it does poorly in sustained heat. It pollinates itself, so a variety stays true from seed and farms can save their own. It is also the more demanding and vulnerable of the two main species: lower yielding than robusta, and susceptible to coffee leaf rust and coffee berry disease, the two diseases that have shaped most of the last century's breeding. Its narrow genetic base is part of why — there is little natural resistance to select from — and much modern breeding has worked by bringing in genes from robusta through the Timor Hybrid.

What it tends to taste like
Arabica is generally described as having more perceptible acidity, more sweetness and a wider range of aroma than robusta, with a lighter body and less bitterness. That is the trade's settled description of the two species; CoffeeHQ has tasted neither side by side and cites no sensory study for it.
A tendency, not a guarantee
Those are tendencies of the species grown well, picked ripe and roasted with care. A low-grown, strip-picked, dark-roasted arabica can be flatter and harsher than a good robusta, and "100% arabica" on a label is a statement about botany, not a guarantee of quality. Variety, altitude, processing and roast move the cup further than the species name does.
What it is used for
Almost all speciality coffee, most filter coffee and the larger part of the world's roasted coffee. In espresso it is used alone or blended with a proportion of robusta for body and crema.
Caffeine content
Generally contains less caffeine per bean than robusta, though roast, dose and brew method affect the cup far more than species alone.
For what ends up in a cup, the caffeine estimator gives a range by brewing method and dose.
Varieties of arabica
A variety is a distinct, named type within a species — the level at which most of the differences between coffees are bred and selected.

How this page was put together
A synthesis of published botanical and agricultural research, in CoffeeHQ's own words. Taste descriptions are tendencies reported in that literature, not the result of CoffeeHQ tasting. Last reviewed 2026-10-09.
What we have deliberately not stated
- A date for the hybridisation that produced arabica. Published estimates span several hundred thousand years and depend on the method used.
- Caffeine content as a percentage. The comparison with robusta is well established; CoffeeHQ has not verified a figure precise enough to print.
