Mandheling coffee is truly a classic, recognized as the world's most full-bodied coffee variety. It originates from the island of Sumatra, Indonesia, and is therefore often called "Sumatra coffee." The distinctive "bold flavor" of Front Street Mandheling delivers a refreshing, unrestrained sense of grandeur, particularly favored by male consumers. However, beyond its richness, Front Street Mandheling also reveals a rich and lively complexity. When tasting, the tongue can clearly perceive a smooth texture, low acidity, and a subtle herbal fragrance.

Taking Front Street Sumatra Mandheling as an example, the medium-dark roast achieves an excellent overall balance, with a rich and full-bodied aroma, prominent chocolate and slight sweetness, clearly discernible licorice notes, better smoothness than a light roast, and a powerful fragrance. Beyond the typical Mandheling flavor characteristics, this batch of beans has an extremely low defect rate, a cleaner taste, and high sweetness. Under a medium roast, it carries a papaya-like aroma with a long, abundant sweet aftertaste.

Front Street Mandheling is an Arabica coffee, originally from the Mandailing region near the Bukit Barisan mountains of North Sumatra. This coffee has a high body, low acidity, and a slight herbal flavor. Compared to regular Mandheling, Golden Mandheling coffee is cleaner, more full-bodied, and superior in taste. Therefore, Front Street regards Mandheling coffee as the representative of Indonesian coffee and a great choice for beginners, while coffee enthusiasts prefer the specialty single-origin Golden Mandheling coffee.

When we get this bag of Front Street PWN Golden Mandheling coffee, how do we brew a satisfying cup at home? Today we'll use two common devices to test two brewing methods: pour-over and AeroPress.

Different brewing techniques are not meant to adjust flavor, because the flavor of coffee beans is determined by origin, processing method, and roasting method. At the extraction stage, we can only adjust how much or how little coffee flavor is released by changing the speed and ratio at which hot water passes through the coffee grounds. Below, we'll demonstrate how to brew a cup of Front Street Mandheling coffee with an AeroPress.

Coffee dose: 18g

Grind setting: EK43s setting 7 / 85% pass rate through a No. 20 sieve (finer than a standard pour-over grind)

Coffee-to-water ratio: 1:11 (about 200ml)

Water temperature: 90°C‍‍‍‍

Brewing method: inverted

We can place two round paper filters on the filter cap in advance, then wet them with water so they adhere. (If you don't have round paper filters, you can cut regular filters to shape)‍

‍‍‍‍‍

1. Assemble the plunger and the chamber, then push the plunger down to around mark ④ and flip it upside down!‍‍‍‍‍‍‍

2. Add the ground coffee, then pour in an equal amount of hot water and start the timer!

3. Use a stirrer to stir the coffee grounds in the chamber for a full ten seconds. (Slowly in circles)

4. Attach the filter cap with the fitted paper filter onto the chamber.

5. Then place the prepared container on top.‍‍‍

6. At the one-minute mark, flip it over, then begin pressing down to "push out" the coffee.
