Kona coffee is grown on the slopes of Mauna Loa and Hualalai on the Big Island of Hawaii , one of the only commercially produced coffees grown in the United States. Its price reflects a small growing region, high labor costs, strict state grading standards, and a flavor profile that is smooth, low-acid, and distinctly different from Central American or African coffees. This guide covers what makes Kona coffee unique, the 100% Kona vs Kona blend distinction, how the grading system works, and what to look for when buying.
