The two main varieties of coffee viz., Arabica and Robusta are grown in India. Arabica is mild coffee, but the beans being more aromatic, it has higher market value compared to Robusta beans. On the other hand Robusta has more strength and is, therefore, used in making various blends.

Arabica coffees (or Arabicas) have a delicate flavor and balanced aroma coupled with a sharp and sweet taste. They have about half the amount of caffeine compared to Robustas. Four popular varieties of Arabica coffee are Kent, S.795, Cauvery, and Selection 9.

Robusta coffee (or Robustas) has twice the level of caffeine compared to Arabicas. Robusta coffees have a robust taste, a grainy essence, and an aftertaste somewhat similar to that of peanuts. Two popular varieties of Robusta coffee are S.274 and CxR.
