Kona Coffee: Hawaii's Volcanic Treasure

Kona coffee is produced in Hawaii. It can only be grown on volcanic slopes, making it a rare variety. The flavor is rich and mellow, with a subtle wine-like aroma, moderate acidity, and an extremely special taste profile. Due to decreasing production, its price now rivals Blue Mountain coffee.

Kona coffee beans are produced in the Kona region of Hawaii. These coffee beans can only be cultivated on volcanic slopes, belonging to a rare variety. Hawaii, a beautiful tropical Pacific island, not only boasts scenic beauty but also produces the famous Kona coffee. The name "Kona" comes from its main production areas located in the northern and southern Kona districts and the slopes of Mauna Loa volcano on the main island. This variety is one of the most expensive coffees in the world, and only coffee produced in the Kona region can bear the title of "Kona Coffee."

Additionally, coffee beans grown and strictly certified in the region along the southwestern coast of Hawaii's main island, spanning 20 miles long and 2 miles wide, at elevations between 150-750 meters, covering the volcanic slopes of Hualalai and Mauna Loa, can only be sold under the Kona trademark name. Due to the decreasing production of coffee beans, the price approaches that of Blue Mountain coffee. The narrow coastal belt of Kona produces the world's best-tasting coffee, and its production ranks among the world's highest. In less than 2,600 acres of coffee land, Kona can still produce 2 million pounds of coffee beans annually.

The Rarity and Quality of True Kona Coffee

True Kona coffee is indeed a worldly treasure, not easily found. According to the evaluation standards of the Hawaii Department of Agriculture, coffee beans are classified into four grades based on size, weight, and quality ratios: Extra Fancy, Fancy, Prime, and Gr.No.1 (100% KONA). Each bag must be accompanied by complete certification documents from the Agricultural Committee, with grade markings printed on burlap sacks. Due to extremely limited production and high costs, coupled with increasing demand for specialty coffee, the market price of Kona coffee rivals Jamaican Blue Mountain, and high-quality Kona beans are becoming increasingly difficult to purchase.

Ideal Growing Conditions

World-popular Kona coffee is nurtured by Hawaii's special climate. The Kona region's elevation is around 600m, but due to its maritime climate characteristics, its climate conditions are similar to regions in Central America at 1200m elevation. The mountainous areas are rainy and much cooler compared to the plains. Although Hawaii is often affected by tornadoes, the climate conditions are indeed very suitable for coffee cultivation. Additionally, Hawaii has abundant rainfall and sunshine, with no worries about frost damage.

The climate conditions are extremely suitable. In the morning, gentle sunlight passes through moisture-filled air. By afternoon, the mountains become more humid and foggy, and the moving white clouds in the sky serve as natural sunshades for the coffee trees, while nights become clear and cool. These suitable natural conditions give Kona coffee a very high average yield, reaching 2,240 kilograms per hectare. Combined with fertile soil and farmers' meticulous management, this creates a climate perfect for coffee growth, making Kona coffee a premium product in the market.

FrontStreet Coffee's Kona Coffee Roasting Recommendations

Like Blue Mountain coffee, Kona coffee has low density. For low-density beans, the initial roasting temperature cannot be too high. When sweetness emerges and the color turns light yellow, due to high moisture content, sufficient steaming time is needed. The coffee beans are clean, crisp, and have a solid, weighty feel. Kona coffee should not be roasted too dark; medium-light roasting (City to Full City-) is recommended.

FrontStreet Coffee suggests keeping detailed records before roasting: coffee bean moisture content, density, origin, processing method, roasting room temperature and humidity, etc., and planning your roasting curve. Record relevant chemical and physical changes during the roasting process, as this will help you better understand the final roasting results and improve your roasting curve.

Roasting Curve:

Preheat the roaster to 200°C and load the beans, with the damper set to 3. After 1 minute, adjust the heat to 150°C, keeping the damper unchanged. Roast until 5'35" when the temperature reaches 150°C, the bean surface turns yellow, the grassy smell completely disappears, and dehydration is complete. Adjust the heat to 140°C and change the damper to 4.

At 9'30", ugly wrinkles and black spots appear on the bean surface, and the toast aroma clearly transforms to coffee aroma, which can be defined as the prelude to first crack. At this point, listen carefully for the sound of first crack. At 9'30", first crack begins, reduce the heat to 70°C, open the damper fully (be very careful when adjusting heat - don't reduce it so much that the cracking sound disappears). Turn off the heat at 182°C and unload at 193.4°C.

Medium-roasted Kona coffee primarily achieves balanced, mellow honey sweetness and an elegant, substantial but not heavy mouthfeel. The brewed coffee releases mulberry aroma that brings a sweet happiness. The aftertaste features a smooth malt bitterness-sweetness that slides into the throat, then resurfaces when exhaling. When cooled, it becomes like a cup of mulberry tea.
