We sell 100% Kona coffee, NOT a Kona blend. Grading coffee is regulated by the state of Hawaii Department of Agriculture according to size, shape, and number of defects in each bean. The lowest grade in the system is Hawaii Number 3, and the Kona label is not allowed to be used with that. Coffee products with less than 100% Kona coffee must be labeled Kona blend. There must be at least 10% Kona coffee by weight. Hawai‘i’s production of coffee makes up only 0.04% of total world coffee production, and Kona coffee is a subset of Hawaiian coffee.
