"Coffee is native to tropical Africa and is grown for its berries which are picked, pulped and processed to produce a dried seed which is roasted. Hawaii’s coffee is considered by many to have the finest flavor in the world due to the rich volcanic soils and optimal climate.
Coffee is a dark green, small tree, growing to 15 feet unpruned. Many commercial trees are kept at half that height. All ‘Kona Coffee’ is C. Arabica. There is a dwarf C. Arabica called 'Cattura'. It is a highly productive tree with high quality beans. There is also a ‘Coffee Liberica,’ which is a large tree with large leaves, flowers, and berries, and has been used to make instant coffee.
Coffee is grown in most Hawaii climates. The trees require regular fertilization. Local companies process and roast homegrown coffee for clients to sell or give as gifts."
