The robusta plant has a greater crop yield than that of arabica, contains more caffeine (2.7% compared to arabica's 1.5%), [7] and contains less sugar (3–7% compared to arabica's 6–9%). [8] As it is less susceptible to pests and disease, [9] robusta needs much less herbicide and pesticide than arabica.
The caffeine concentration of liberica beans is the lowest of the three cultivars, with 1.23 g/100 g, where arabica has 1.61 g/100 g and Robusta has 2.26 g/100 g. [ 11 ] Taxonomy
The two most economically important varieties of coffee plants are the Arabica and the Robusta; approximately 60% of the coffee produced worldwide is Arabica and ~40% is Robusta. [5] Arabica beans consist of 0.8–1.4% caffeine and Robusta beans consist of 1.7–4.0% caffeine. [6]
Robusta strains also contain about 40–50% more caffeine than arabica. [56] Consequently, this species is used as an inexpensive substitute for arabica in many commercial coffee blends. Good quality robusta beans are used in traditional Italian espresso blends to provide a full-bodied taste and a better foam head (known as crema).

Caffeine content in coffee varies widely depending on the type of coffee bean and the method of preparation used; [9] even beans within a given bush can show variations in concentration. In general, one serving of coffee ranges from 80 to 100 milligrams, for a single shot (30 milliliters) of arabica-variety espresso , to approximately 100–125 ...
