Whole Bean Coffee Kona is really great coffee. The success of their cultivation is due to the environment in which they''re grown. There are two active volcanoes on this part of the Big Island, and therefore the soil is porous and mineral-rich. The area also has an ideal climate for delicate trees: sunny mornings, rainy or windy evenings, and cool nights. All these factors make it possible to grow one of the most elite varieties of Arabica in the world: Kona.
