FrontStreet Coffee - Introduction to Hawaiian Kona Coffee

Hawaii, the beautiful tropical islands in the Pacific, not only boasts picturesque scenery but also produces the famous Kona coffee. Kona is also named after its origin. Only coffee beans grown in the area on the southwest coast of the Big Island of Hawaii, stretching 20 miles long and 2 miles wide, at elevations between 150-750 meters, covering the slopes of Hualalai and Mauna Loa volcanoes, and undergoing strict certification, can be sold under the Kona trademark name.

Coffee Characteristics

Kona coffee, of the Arabica variety, has an attractive appearance with uniformly shaped beans. It offers a crisp taste, medium body, slight acidity, rich aroma, and a long-lasting aftertaste.

Coffee Grading

Kona coffee is graded into four levels: Extra Fancy, Fancy, Prime, and Grade No. 1. Due to its limited production and high cultivation costs, coupled with increasing demand for specialty coffee, Kona's market price rivals that of Jamaican Blue Mountain. High-quality Kona beans are becoming increasingly difficult to purchase.

Growing Environment

The excellent quality of Kona coffee is attributed to its suitable geographical location and climate. Coffee trees grow on volcanic slopes, where the geographical location ensures the required altitude for coffee cultivation. The dark volcanic ash soil provides essential minerals for the coffee. This is likely due to Kona Island's rich volcanic black mud, which has moderate acidity, abundant mineral content, and appropriate moisture levels.

Additionally, every afternoon, a cloud drifts over Kona Island to block the sunlight, protecting the delicate coffee seedlings. The climate conditions are extremely suitable: gentle morning sunlight filters through moisture-filled air, while afternoons become more humid and foggy in the mountains, with surging white clouds serving as natural umbrellas for coffee trees, while evenings become clear and cool. These favorable natural conditions enable Kona coffee to achieve very high average yields, reaching 2,240 kilograms per hectare, whereas Latin American coffee production averages only 600-900 kilograms per hectare.

Cultivation Pattern

Kona coffee is grown using unshaded cultivation methods. Hawaii belongs to an island climate, where clouds often drift in, creating a natural shading effect. Hawaiian coffee farmers typically maintain their farms in exceptionally clean condition. Fertile land combined with farmers' meticulous management and climate suitable for coffee growth has established Kona coffee as a premium product in the market.

Processing Methods

Kona coffee uses washed processing and natural sun-drying methods. Hawaii's clean, sweet mountain spring water provides ideal conditions for the washed processing method, which creates the bright, clear appearance and pure, fresh taste of Kona coffee beans. The washed coffee beans are then placed on large flat surfaces to dry naturally in the sunlight.

Kona coffee green beans are typically packaged as single-origin small batches. Kona coffee is also often blended with other coffee beans to create blended coffees. Coffee blends containing Kona beans are labeled as "Kona Blend" on the packaging. Unfortunately, the Kona content in these blends may be very low - in Hawaii, the minimum Kona content standard for blends using the "Kona" label is only 10%.
