Kona coffee was carefully cultivated by Japanese settlers in Hawaii during the Meiji period, and has since become a world-famous coffee. The coffee beans grown by a Japanese grandfather are completely pesticide-free, hand-picked, and slowly roasted in a handmade roaster, resulting in an elegant and refined flavor. These world-class coffee beans are put into alcohol to create a coffee liquor. Kona coffee is characterized by its low acidity, low bitterness, and strong aroma, and its rich flavor matches that image.
