Few coffee drinkers know that all coffee is not the from just one species -- there are at least two main species: coffea arabica and coffea canephora. Both are known commonly as Arabica and Robusta respectively.Naturally, the biggest difference between these two species is taste. Robusta coffee is higher in caffeine and some say has an inferior taste. Nearly eighty percent of the coffee sold in grocery stores are arabica. Brazil grows arabica, or has up until now because profit was in lots of coffee beans over some quality coffee beans.
The coffee plant is a woody perennial evergreen that belongs to the Rubiaceae family. Because it grows to a relatively large height, it is more accurately described as a coffee tree.
