Flavor and Taste Differences Between Golden Mandheling Coffee and Blue Mountain Coffee Beans - Pour-Over Brewing Tutorial

Indonesian Mandheling coffee and Jamaican Blue Mountain coffee both belong to the category of bitter-toned coffees with chocolate and nut flavors. Generally, if you want to enjoy a balanced taste, FrontStreet Coffee's barista would recommend Jamaica's Blue Mountain No. 1. If you prefer rich coffee with herbal and spice aromas, FrontStreet Coffee suggests trying Indonesia's Golden Mandheling. Below, FrontStreet Coffee compares the characteristics of these two premium coffees.

Blue Mountain No. 1 Coffee: Originating from Jamaica's High-Altitude Blue Mountains

Jamaica's Blue Mountains are the highest terrain region in the Caribbean, featuring a tropical rainforest climate. During the rainy season each year, precipitation reaches 1800-2000 millimeters. The sloping steep terrain facilitates drainage, allowing local vegetation to receive adequate irrigation. The Blue Mountain area boasts beautiful scenery, excellent air quality, and fertile volcanic soil that promotes crops bearing flavorful fruits. Locals grow coffee trees alongside banana and avocado trees. The high-altitude Blue Mountains are often shrouded in clouds and mist, providing natural shade for coffee trees. To protect the Blue Mountain environment, Jamaican law stipulates that only areas below 1700 meters altitude can cultivate crops, and strictly requires that Arabica coffee grown in the specific 910-1700 meter altitude range can be called Jamaica Blue Mountain Coffee. The region is divided into four producing areas: St. Mary, St. Thomas, St. Andrew, and Portland, covering one-third of the entire Blue Mountain cultivation area.

Unlike many producing regions that have switched to higher-yield coffee varieties to increase production, Blue Mountain has consistently cultivated the recognized high-quality heirloom variety—Typica. After nearly three hundred years of adaptation and propagation, Blue Mountain Typica has not only integrated with the local island terroir but also evolved better disease resistance, particularly showing much stronger resistance to coffee berry disease than typical Typica varieties. FrontStreet Coffee believes that the delicate and clean flavor of Blue Mountain is inseparable from Jamaica's dedicated cultivation of the Typica variety. FrontStreet Coffee's Blue Mountain No. 1 coffee is produced by Jamaica's historic Clifton Mountain Estate, using traditional washed processing.

Clifton Mountain Estate places freshly picked coffee cherries in water tanks for flotation, removing the pulp and skin before the coffee beans ferment. Overnight fermentation produces large amounts of acidic substances, allowing the mucilage layer to separate from the surface. The parchment beans are then placed in sunlight for drying until the moisture content reaches the standard, after which they are packaged and stored in warehouses before being sent for quality inspection. The washing process makes Blue Mountain coffee beans' inherent flavor cleaner and more transparent, with more stable quality.

Indonesian Golden Mandheling: From the Mysterious Island of Sumatra

Mandheling originates from Indonesia's mysterious Sumatra island. The entire Sumatra is divided into eight provinces, with only the high-altitude Aceh and North Sumatra provinces cultivating Arabica coffee on a large scale. Sumatra belongs to the tropical rainforest region, where mountains and forests are often shrouded in clouds and mist, adding a layer of mystery to Sumatra. Locals plant coffee trees around two major volcanic lakes: Lake Tawar and Lake Toba. The Gayo Mountains around Lake Tawar have ideal coffee growing conditions, widely adopting organic cultivation methods, plus a long history of coffee cultivation, making the coffee quality and yield from this area higher. Many green coffee merchants also place greater importance on this region, including the locally renowned Pwani Coffee Company (PWN). The Golden Mandheling coffee on FrontStreet Coffee's menu comes from PWN Company, using Indonesia's unique wet-hulled processing method.

The wet-hulled processing method involves first removing the coffee cherry's skin and pulp, followed by brief fermentation and drying. When the beans are semi-dry, the parchment layer is removed, and drying continues in the later stages until the moisture content drops to 12%. Since each step is completed in 70-90% humidity environment, and the parchment layer has been removed before the final drying step, the "exposed" green beans easily absorb moisture from the air, resulting in coffee with more woody, herbal, and spicy mellow aromas—this is also a unique flavor characteristic of Indonesian coffee producing regions.

Both Blue Mountain No. 1 and Golden Mandheling Belong to the Highest Local Grades

Jamaica grades Blue Mountain green beans based on specifications, defect rates, cupping flavors, and other criteria. Blue Mountain coffee is divided into four grades: Blue Mountain No. 1, Blue Mountain No. 2, Blue Mountain No. 3, and hand-selected Blue Mountain Peaberry. Among these, Blue Mountain No. 1 coffee beans have the highest grade, with green bean specifications above 17 screen size and moisture content around 10-12.5%. After roasting, they possess a perfect balance of acidity, sweetness, bitterness, body, and aroma, making them an extremely precious batch of Blue Mountain coffee. To ensure Blue Mountain coffee beans maintain better quality until roasting and avoid moisture infiltration during transportation, Jamaicans insist on using handcrafted wooden barrels as carriers for Blue Mountain green beans. Wooden barrels have also become one of the important symbols of Jamaican Blue Mountain coffee.

Meanwhile, Golden Mandheling coffee is PWN Company's exclusive signature product. Since PWN registered the "Golden Mandheling" trademark early on, only Mandheling produced by PWN Company can be called "Golden Mandheling." The characteristic of Golden Mandheling coffee lies in the multiple screenings of its green beans, resulting in consistently high overall quality. PWN purchases Mandheling green beans above 18 screen size, with fewer than 3 defective beans per 300g sample, reaching G1 grade—the highest grade for Indonesian green beans. Subsequently, they strictly follow standards for 1 machine selection + 3 manual defect selections, ensuring uniform color, shape, and size of Mandheling coffee beans. Therefore, PWN Golden Mandheling tastes cleaner and more transparent, with more pronounced body and sweetness.

FrontStreet Coffee's two coffees both come with corresponding certification documents. The wooden barrels for green beans and burlap bags are displayed at FrontStreet Coffee's Dongshankou store. Everyone can observe them during their leisurely coffee-drinking time.

Cupping Flavors of Blue Mountain No. 1 and Golden Mandheling Coffee

Before launching a coffee bean, FrontStreet Coffee always evaluates it through cupping. Since both coffees emphasize nutty and rich aromas, FrontStreet Coffee uses medium-dark roasting to retain some acidity. Golden Mandheling coffee has more prominent body, so its roast level is darker than Blue Mountain No. 1 coffee.

Cupping is the evaluation of coffee bean quality and flavor. Unified standards allow for more objective identification of the strengths and weaknesses of the flavors presented by the beans, as well as their characteristics. Through cupping, FrontStreet Coffee found that PWN Golden Mandheling not only has aromas of dark chocolate, nuts, and caramel, but also herbal spice and pine flavors, with a dark chocolate aftertaste, full lingering finish, high clarity, and gentle fruit acidity as the temperature drops.

When FrontStreet Coffee receives the Blue Mountain No. 1 green beans, they are uniform, plump, and consistently sized, displaying a transparent blue-green color overall. After roasting, FrontStreet Coffee conducts cupping. The dry aroma presents nuts, sweet melon, and chocolate. After adding hot water, aromas of oolong tea, caramel, honey, and dark chocolate emerge. The taste reveals rich dark chocolate, roasted hazelnuts, cream, and brown sugar, with clean and clear flavors, rich body, and persistent aroma.

FrontStreet Coffee's Brewing Recommendations

FrontStreet Coffee believes the greatest characteristic of these two coffees is their body and roundness, so FrontStreet Coffee's barista consistently uses the KONO dripper for extraction. The KONO dripper has only one ventilation area in its quarter-ribs. When the water level rises above the rib area, the water volume in the dripper continuously increases, creating pressure through the water's weight. Since the outlet is relatively small, it can extend the contact time between coffee particles and water. As water flows through, it more effectively extracts soluble substances, thereby enhancing the coffee's rich and full-bodied taste. FrontStreet Coffee hopes every customer can enjoy the full aroma in their coffee, so they only ship coffee beans roasted within 5 days, allowing everyone to enjoy the complete flavor period upon receiving them.

Filter: KONO
