in 1825, the person who was one of the royal family of hawaii went to britain with the king of hawaii and brought coffee plants on the way home. those plants spread to many regions of hawaii. in 1828, coffee plants were planted in the kona region. after that, many farms were made there. but, because of pest damage and the price decline of coffee, most farmers quit their jobs. in this situation, japanese immigrants moved to the kona region and started to grow coffee to pay their land cost by coffee. this is the beginning of kona coffee. now, kona coffee is drunk at the dinner party in white house because this is the only coffee that is grown in america and the quality is quite high.
