Only coffee grown in the North and South districts of Kona may use the geographic designation of Kona. The KCFA feels that the use of the word “Kona” in a 10% Kona Blend (90% of which is non-Kona) is abusive. Ā There are no Federal regulations protecting Kona Coffee.Ā Anyone outside of Hawaii can use the word āKonaā as they wish- e.g. Kona cream gum.
