Mandheling Coffee In the mid-17th century, the Dutch brought coffee trees to Indonesia. Last year Indonesia exported 300,000 tons of coffee, making it the world's fourth-largest coffee producer. About 75,000 tons of that is Arabica coffee. Ninety percent of these coffees are grown by smallholders on farms of one hectare or less.

Indonesia's main coffee-producing regions include Sumatra, Java, and Sulawesi, among which "Mandheling" from Sumatra is the most famous. In the northern part around Lake Tawar, it can be called Aceh coffee or Lake Tawar coffee, while the Lintong and Lake Toba area can be called Mandheling. It is divided into eight provinces in total, but only two provinces grow coffee in large quantities—Aceh Province and North Sumatra Province. The most representative coffee-producing area in these two provinces is the Gayo Mountains around Lake Tawar in Aceh Province, where coffee is grown by the local indigenous Gayo people. Coffee in North Sumatra Province is grown around Lake Toba, a body of water so enormous that it is the largest volcanic lake in the world. The Mandheling produced around Lake Tawar and Lake Tawar is the famous "Two Lakes, Two Mandhelings," and to the south of Lake Toba is the Lintong production area.

Country: Indonesia Region: Sumatra, Lintong Altitude: 1100-1600 meters Variety: Typica, Caturra Processing Method: Wet-Hulled Flavor: Baked toast, nuts, caramel, pine, herbs

Coffee Producing Region Mandheling is actually not specifically a coffee bean variety, nor the name of a coffee-producing region, but the name of a tribe. It was mistaken by the Japanese for the name of a coffee bean, and it has been used that way ever since.

Front Street Lintong Mandheling comes from the Lintong highlands in north-central Sumatra, near Lake Toba. Front Street Lintong Mandheling grows on highland terrain at an altitude of 1000-1500 meters. Within its territory there are many volcanoes and numerous volcanic lakes, among which the most famous coffee-growing area is located at Lake Lawar. The fresh soil comes from volcanic earth, an original brown podzolic substance mixed with a considerable amount of organic matter. Combined with the local tropical rainforest climate and abundant rainfall year-round, this provides the most suitable geographical and climatic environment for coffee growth.

Front Street Lintong Mandheling is the regular version of Mandheling. Front Street Lintong Mandheling also uses the conventional wet-hulled method, which creates its characteristics of low acidity and high body. However, one situation that arises from using the wet-hulled method is that, because the semi-hard, semi-soft wet raw beans are prone to being crushed when the parchment and mucilage layer are removed, the beans become damaged and split open like a sheep's hoof, commonly known as sheep-hoof beans. These are not defective beans, and can be said to be a very notable characteristic of Front Street Mandheling.

Front Street Lintong Mandheling does not put much effort into screening, so there will be cases of uneven bean size. The lack of refinement in processing can easily lead to instability in the finished coffee beans, but it does not diminish people's love for its rich, full-bodied flavor.

Coffee Variety

The variety of Mandheling is a mix of Ateng and Tim Tim, among which the coffee variety of Golden Mandheling is Ateng, whose name comes from the Central Aceh region of Aceh Tenggah. The Ateng series is the collective name for Catimor varieties on Sumatra and other Indonesian islands. It is a hybrid of Arabica and Robusta, widely planted on Sumatra, with high yield, strong resistance to coffee leaf rust and coffee berry disease, and relatively good performance in cupping.

Coffee Processing Method Wet-hulling is a method of processing coffee beans quickly, giving the flavor a rich and intense expression with a very distinct character. Coffee drying generally takes 2-3 weeks on average, because humidity in Indonesia is between 70-90% year-round, with constant typhoons and heavy rainfall. In such a humid climate in Indonesia, drying coffee becomes a major problem, and at the same time farmers pursue more efficient economic returns. It differs clearly from the washed method: the skin and pulp are removed, the parchment and mucilage are retained and fermented in a water tank, then the mucilage is washed off, and the beans are sun-dried with the parchment for 2-3 days until the moisture content reaches 20-24%. Removing the parchment is then done to carry out the final step of drying. In this way, sunlight shines directly onto the surface of the raw beans, causing the raw coffee beans to dry rapidly, 2-3 times faster than washed processing. Therefore, the beans are relatively easy to crush and form small gaps. This is what we commonly call horse-hoof or sheep-hoof beans.

Front Street Coffee (FrontStreet Coffee) Roast Analysis Front Street's roaster used a medium-dark roast for this Front Street Lintong Mandheling coffee bean in order to highlight Mandheling's rich, abundant spice and herbal notes as well as its full-bodied mouthfeel.

Front Street Coffee (FrontStreet Coffee) Brewing Recommendation For brewing Front Street Lintong Mandheling coffee, Front Street uses a Kono dripper. Kono's ribs do not reach even half the height of the entire dripper. This design is actually intended to ensure that the filter paper clings tightly to the dripper wall after being wet, thereby restricting airflow. This increases the time for the coffee grounds to absorb water, so that the brewed coffee is overall more even and the full-bodied mouthfeel is enhanced. It is suitable for brewing medium-dark roasted coffee beans such as Front Street Golden Mandheling and Front Street Jamaica Blue Mountain. Also, the groove skeleton at the bottom of the Kono dripper is the key design that allows the subsequent brewing to produce a siphon effect.
