Usually, the more difficult it is to harvest a coffee bean, the higher the value per kg will most likely be once it reaches espresso roasteries all over the world. Not each part of the world has this topography though. Brazil, as an example, has massive space of flat, suitable land at high altitude. This permits for bulk harvesting performed by machines. This, in turn, permits Brazil and different nations with similar land to be main exporters of espresso beans world-wide.
