Robusta coffee is coffee made from the Coffea canephora plant, a sturdy species of coffee bean with low acidity and high bitterness. C. canephora beans, widely known by the synonym Coffea robusta, are used primarily in instant coffee, espresso, and as a filler in ground coffee blends.
Robusta has its origins in central and western sub-Saharan Africa. It is easy to care for, has a greater crop yield, has almost double the amount of caffeine and more antioxidants, and is less susceptible to disease than arabica coffea. It represents approximately 40% of global coffee production, with arabica constituting the balance.
Roasted robusta beans produce a strong, full-bodied coffee with a distinctive, earthy flavour, but usually with more bitterness than arabica due to their high pyrazine content.

Cultivation and use
Some 37% to 40% of the coffee produced in the world is robusta. It is mostly grown in Vietnam, where French colonists introduced it in the late 19th century, though it is also grown in India, Africa and Brazil, where it is often called conilon. In recent years, Vietnam, which produces mostly robusta, has become the world's largest exporter of robusta coffee, accounting for over 40% of the total production. It surpasses Brazil (25% of the world's production), Indonesia (15%), India (6%), and Uganda (4,5%). Brazil is still the biggest coffee producer in the world, producing one-third of the world's coffee, though 70% of that is C. arabica.
Robusta is easier to care for and has a greater crop yield than C. arabica, so is cheaper to produce. Roasted robusta beans produce a strong, full-bodied coffee with a distinctive, earthy flavour, but usually with more bitterness than arabica due to their pyrazine content. Since arabica beans are believed to have a smoother taste with more acidity and a richer flavour, they are often considered superior, while the culture and processing of robusta has for a long time been neglected and focused on unwashed beans, resulting in a harsher taste. However, the powerful flavour can be desirable in a blend to give it perceived "strength" and "finish", noticeably in Italian coffee culture, and carefully processed, washed robustas can be superior in quality and provide a milder taste than some lower quality arabicas. Good-quality robusta beans are used in traditional Italian espresso blends, at about 10-15%, to provide a full-bodied taste and a better foam head (known as crema). Robusta is also used as a stimulant, diuretic, antioxidant, and antipyretic, and relieves spasmodic asthma.

Plant
Robusta is a species of flowering plant in the family Rubiaceae. Though widely known by the synonym Coffea robusta, the plant is currently scientifically identified as Coffea canephora, which has two main varieties, C. c. robusta and C. c. nganda. The plant has a shallow root system and grows as a robust tree or shrub to about 10 m tall. It flowers irregularly, taking about 10-11 months for cherries to ripen, producing oval-shaped beans. The robusta plant has a greater crop yield than that of arabica, contains more caffeine (2.7% compared to arabica's 1.5%), and contains less sugar (3-7% compared to arabica's 6-9%). As it is less susceptible to pests and disease, robusta needs much less herbicide and pesticide than arabica.
Originating in upland forests in Ethiopia, robusta grows indigenously in Western and Central Africa from Liberia to Tanzania and south to Angola. It was not recognized as a species of Coffea until 1897, over 100 years after Coffea arabica. It is also reportedly naturalized in Borneo, French Polynesia, Costa Rica, Nicaragua, Jamaica, and the Lesser Antilles. In 1927 a hybrid between robusta and arabica was found in Timor. This strain was subsequently used to breed rust-resistant plants.
