Arabica (Coffea arabica), named for the Arabs, is the better and more

equator, both in the western and eastern hemispheres, at high altitudes.
There's a whole wide world of beans out there, but almost all commercial coffee comes from the beans of only two varieties of plant - coffea arabica or coffea robusta. You're forgiven if you think robusta to be the more appealing of the two.
