While many shops sell Kona coffee, it's important to be cautious as not all provide a superior product. Kona coffee quality varies based on factors like grade, which is determined by bean size, defects, and overall quality. The top grades are "Kona Extra Fancy," "Kona Fancy," "Kona Number 1," and more. Difference Coffee, for instance, sources its beans from one of Kona's esteemed coffee estates, guaranteeing the finest and most flavorful beans Hawaii has to offer. This ensures that you can enjoy the delightful taste of Specialty Grade Kona coffee.
