Kona Coffee

Kona Coffee is one of the most expensive coffee in the world. Kona coffee is a trademark for arabica coffee (see the article on coffee arabica) grown in the area of Hualalai and Mauna Loa in the North and South Kona Districts of the Big Island of Hawaii.
Kona Coffee trademark is introduced by an English named Henry Nicholas Greenwell. However, Greenwell is not the person who first brought coffee to Kona. Reverend Samuel Ruggles was the one who brought this coffee in 1828.
Not all arabica coffee can be called as Kona Coffee. Only Coffee cultivated in the North and South districts of Kona on the Big Island of Hawaii that can be called as Kona Coffee.
To buy 100% pure Kona Coffee, we need to check the label. If it says "Kona Coffee Blend" it means the coffee was only contains 10% Kona Coffee. It is blended with other lower grade coffee. If you buy Kona Coffee, you are advised to buy it in the form of whole coffee beans. This will keep the freshness of the Kona Coffee flavor for about 3 months if stored in an airtight container.
