Most of the coffee grown in Kaʻu is in a climatic band from 1,000' to approximately 2,500' above sea level. The climate and soils of the region have produced some of the best coffees in the world. Since entering coffee bean and cupping competitions in 2007 at the Specialty Coffee Association of America annual events Kaʻu has placed among the top ten coffees in the world.
Why does Kaʻu coffee score so highly? The soils of the district are young volcanic ash deposits from nearby Kilauea volcano; they are well drained and acidic in nature which the coffee plants love. The climate of the region provides sunny hot mornings, then a characteristic cloud filled afternoon with light rains. Then at night the cold mountain air flows off of Mauna Loa towards the coast cooling the region and allowing the coffee plants to store energy and sugars within the ripening beans.
