What does robusta mean?
Robusta is a species of coffee plant, scientifically known as Coffea robusta, and the name is also commonly used for coffee made from its beans. Compared with Arabica, robusta usually has a stronger, more bitter taste, greater body, and often a higher caffeine content. It is also more resistant to several diseases and environmental stresses that affect coffee plants, which made it especially valuable to growers. Today robusta beans are used in many espresso blends, instant coffee, and traditional preparations where strength and a pronounced flavor are wanted. The word is frequently treated as a mass noun, although “a robusta” can refer informally to a bean, drink, or plant of this kind. Although robusta can describe an especially robust coffee product or plant, its standard reference is the botanical species and the commercial coffee category derived from it. Recognizing the distinction between robusta and Arabica is useful because the two species differ noticeably in flavor, caffeine content, cultivation, and agricultural characteristics.

- A taxonomic name for the species, used as the specific epithet in the botanical name Coffea robusta.
"The café blended its house espresso with a small proportion of robusta for a fuller flavor."
"Robusta is commonly used in coffee blends where a stronger taste and greater body are desired."
"The botanical garden added several plants of Coffea robusta to its collection of tropical crops."
The plural is uncommon; robusta is normally used as a mass noun for the coffee category, while the botanical species name itself does not normally take a plural.
"The roaster offers both arabica and robustas from separate harvests."
Robusta coffee once supplied the industry with hardier plants; today, it survives a growing share of global production as the bold counterpart to Arabica.

Where does robusta come from?
The name comes through botanical Latin from Latin robusta, the feminine singular form of robustus, meaning “strong” or “robust.” It was applied as the specific epithet in Coffea robusta, following the taxonomic convention of using a qualifying Latin term after the genus name. English robust, robustness, and robustly belong to the same Latin root.
