Sumatra · Aceh Origin

Sumatra · Aceh

Aceh Province is located at the northwestern tip of the Indonesian archipelago, straddling both sides of the equator, with a typical tropical equatorial maritime climate, hot like summer all year round, with an average annual temperature of about 27°C, high heat and abundant rain. From October to March each year, influenced by Asian and Pacific air currents, it is Indonesia's rainy season, with abundant rainfall and a cool climate; from April to October, influenced by Australian continental air currents, moisture decreases and the climate is dry and hot, regarded as the dry season. Front Street has cupped many coffee beans from the Aceh origin, including Longberry Mandheling, Front Street PWN Golden Mandheling, Aged Mandheling, and this Tiger Mandheling. Herbal, dark chocolate, high body, clean mouthfeel, and noticeable sweetness are all characteristics of coffee from this origin.

Why is it called Tiger Mandheling?

Tiger Mandheling

This Tiger Mandheling that Front Street sourced comes from Sumatra, the homeland of the Sumatran tiger. This Tiger Mandheling uses 19-mesh coffee cherries (the coffee cherries must be strictly filtered through a screen with 19-mesh holes, in order to make each bean as uniform in size and diameter as possible), and then through three rounds of hand-sorting to select ripe coffee cherries before green bean processing. Therefore, locals use "Sumatran tiger" to describe the nobility and rarity of this 19-mesh selected coffee bean. In Front Street's cupping, the coffee has high viscosity, a smooth mouthfeel, rich agarwood notes and high sweetness, with a long-lasting sweet aftertaste on the palate, reminding one of the image of a Sumatran tiger crawling forward.

Wet-Hulled Processing Method

Wet-Hulling

The wet-hulled processing method first removes the skin and pulp of the coffee cherry, then after a brief fermentation it is sun-dried, then the mucilage and parchment layer are removed, and drying continues in the later stage until the moisture content drops to 12%. Wet-hulled Mandheling coffee beans clearly show varying degrees of挤压 cracking (beans produced by this phenomenon take a horseshoe shape, so they are also called horseshoe beans), and the bean color is on the darker blue-green side.

Because this method shortens the drying time to just two to four days, the fermentation period of the coffee beans is shortened, and the acidity is also greatly reduced. In contrast, the body increases, caramel and fruity aromas are obvious, and it even carries herbal or grassy aromas as well as woody notes, thus forming the unique flavor of the Sumatra origin.

Coffee Bean Varieties

Typica & Caturra

This Tiger Mandheling uses two coffee varieties with obvious sweetness, Typica and Caturra. Typica has bronze-colored top leaves, oval or pointed bean shape, elegant flavor, but weak constitution, poor disease resistance, and low yield. Front Street Coffee, through cupping Typica from multiple origins, can reflect its unique clear and clean flavor and balanced characteristics. Caturra is a Bourbon mutation, with a curved tail end on the coffee bean, round and slender, and both productivity and disease resistance are better than Bourbon , its flavor is overall bright, with good sweetness as well.

Front Street's roaster observed that Tiger Mandheling green beans are round and plump, yellow-green, with good uniformity and relatively high moisture content. The roasting target is medium-dark roast, in order to erase excess acidity and enhance its body and balance.

Front Street Coffee Roasting Record

Charge when the drum temperature reaches 200°C, set airflow to 3, after 30s adjust heat to 160°C, airflow unchanged, turning point at 1'45", maintain heat, at 5'18" the bean surface turns yellow, the grassy smell completely disappears, entering the dehydration stage, reduce heat to 140°C, adjust airflow to 4;

At 7'30" dehydration is complete, reduce heat to 140°C, at 8'55" the bean surface shows ugly wrinkles and dark spots, the toasted bread smell clearly turns into coffee aroma, which can be defined as the prelude to first crack. At this time, listen carefully for the sound of first crack. At 9'00" first crack begins, reduce heat to 110°C, open airflow fully to 5 (adjusting heat must be very careful, not so low that there is no crack sound), develop for 4'00" after first crack, drop at 203°C.

Front Street Coffee Brewing Notes

For darker-roasted coffee beans, in order to highlight the coffee's body, Front Street Coffee chooses the Kono dripper for brewing. The Kono dripper's feature is that it has an immersion function, which can be used to extract more coffee substances and enhance the mellow mouthfeel. The Kono dripper has few ribs and they are located at the bottom, which allows the filter paper to cling tightly to the dripper to achieve the effect of restricting airflow, thereby slowing the water flow rate and increasing water-powder contact time.

Dripper: Kono Meimon

Dose: 15g

Coffee-to-water ratio: 1:15

Water temperature: 88°C

Grind size: medium-coarse grind (about 73% passing rate on a 0.85mm standard sieve)

Front Street Coffee uses staged extraction, blooming with 30g of water for 30 seconds, then pouring in a small stream in circles until 125g for the stage break, and when the water level drops and is about to expose the coffee bed, continue pouring until 225g and stop pouring. When the water level drops and is about to expose the coffee bed, remove the dripper. (timing starts from the beginning of blooming) The extraction time is 2'05".

Brewing flavor: Nuts, Cream, Dark Chocolate, Caramel, Traditional Chinese herbal medicine, with obvious sweetness, and the flavor is relatively clean and clear.
