Botanical varieties
It is about the two varieties of coffee that are sold worldwide. The coffee trees of these varieties are cultivated around the world, in the range between the Tropics of Cancer and Capricorn, throughout more than 60 countries. There are differences between both grains, which help not only to recognize them but to choose the exact combination of both for the realization of the different blends.
Robusta
The Robusta coffee plant is the second most commercialized variety, with 25% of the world coffee production. Unlike Arabica, a 100% Robusta variety can not be made, but it is used to add blends to a greater or lesser extent. It has a higher concentration of caffeine, between 1.7 and 4%. The coffee of this variety grows best in areas where the temperature ranges between 24 ° - 30 ° C. The grain is round, smaller than the Arabica grain and has a straight opening.
Arabica
Arabica coffee is the variety of coffee that is most cultivated and marketed, representing about 75% of world production. Its grain has a lower amount of caffeine than Robusta, between 0.4 and 1.4%. It grows best on land where the temperature ranges between 15 ° - 24 ° C. The shape of its grain is oval with a small opening in the shape of S.
