Combined with Arabica in espresso blends, a perfect harmony with delicious flavour and a pleasant bitterness can be reached. Robusta beans grow in the lowlands, and its cultivation does not require too much effort, as it is often collected by machine, so its price is lower than that of Arabica. Its biggest producers are Brazil and Vietnam.
