There are many different types of coffee varietals and cultivars, all of which are different versions of the same original bean, Coffea Arabica, originating from western Ethiopia. Each version can effect the coffee plants appearance, yield, resistance to disease, and flavor. Coffee varietals are naturally occurring. The coffee plant evolves over time to best survive its natural environment, and thus altering the flavor. Coffee cultivars are not naturally occurring, the coffee plants are typically controlled hybrids. Generating a desired flavor or perhaps a resistance to a common disease.No matter what, whether the bean is artificially or naturally altered, each varietal and cultivar produces its own unique coffee bean and flavors.
