Introduction:Indonesian Mandheling coffee is renowned for its unique rich flavor and deep profile, and among its classics, Golden Mandheling stands out as a flagship representation. This article delves into how to brew this classic Sumatran coffee bean using two common brewing devices: the French press and the moka pot. It not only provides practical parameters such as grind size and coffee-to-water ratio, but also analyzes the flavor differences brought out by different devices, helping you find your optimal brewing method.
Indonesian Mandheling is globally recognized as a classic regional flavor, and among them, Golden Mandheling is a standout. This article will start with the background of coffee cultivation in Indonesia and the origin of the name "Mandheling," using this popular Golden Mandheling as the sample bean. It details how to brew using both the French press and the moka pot, including recommended grind size, coffee-to-water ratio, operation steps, and precautions, taking you through the flavor impact of different brewing methods.
As one of the earliest regions in the world to engage in commercial coffee cultivation, Indonesia introduced coffee farming in the late 1600s, initially taking root on the island of Java. Later, due to the impact of coffee leaf rust, more disease-resistant Robusta was planted, and to this day, Indonesia remains one of the world’s major Robusta producers. However, Arabica, though accounting for only 6%–10% of total production, has given rise to representative specialty beans such as Mandheling.
The name "Mandheling" actually originated from a misunderstanding. During World War II, a Japanese officer tasted an amazing coffee in Sumatra and mistakenly thought the word "Mandailing" mentioned by the shopkeeper referred to the place of origin, when in fact it was the name of the local Mandailing ethnic group. Later, due to transliteration, it became "Mandheling," and PWN was the first company to export it to Japan. Among them, "Golden Mandheling" has become a highly distinctive specialty bean due to its strict selection system and unique processing method.
The PWN Golden Mandheling offered is grown in the Gayo Highlands of Aceh, Sumatra, using the Ateng variety, cultivated at an altitude of about 1100–1600 meters. It is processed using the traditional wet-hulled method, classified as G1 grade and has undergone three rounds of manual hand-picking. Its beans are uniform in appearance with an extremely low defect rate, offering a clean taste and pronounced sweetness, making it an excellent choice for experiencing the flavor of Indonesian Mandheling.
The French press, also known as the French plunger pot, originated in France around the 1850s and consists of a heat-resistant glass carafe and a metal filter. It is a simple yet practical brewing device. Coffee brewed with this method can fully retain coffee oils and delicate flavors, resulting in a smooth texture and rich layers, making it suitable for drinkers who prefer bold flavors.
When using a French press, it is recommended to choose single-origin beans with medium to dark roasts, with a grind size of about medium, roughly 65%–70% coarseness as per standard sieve ratios. A base ratio is 20 grams of coffee beans to 200 milliliters of hot water (approximately a 1:10 coffee-to-water ratio), with water temperature advised to be around 93°C. The steeping time is about 3–4 minutes. Note that during brewing, there is no need to rush to press down the filter; allow the coffee grounds to fully interact with the water before slowly pressing down the plunger to avoid over-extraction and bitterness. It is recommended to pour out the coffee immediately after brewing to prevent over-extraction.
In addition, using freshly filtered soft water can significantly improve extraction quality, as stable water quality helps maintain flavor consistency. If you want to try variations, you can also use it to make milk coffee—just add some hot milk to the French press, gently froth it, and then mix it with the coffee.
Another classic brewing device—the moka pot—originated in Italy and consists of three parts: the lower chamber, the filter basket, and the upper chamber. Its principle is to use steam pressure generated by heating to push water through finely ground coffee, extracting a strong coffee liquid, making it very suitable for users who enjoy intense flavors.
When operating a moka pot, it is recommended to use medium to dark roasted beans, with a grind size slightly coarser than espresso but finer than that for a French press, roughly close to the size of the filter basket holes, to ensure smooth water flow and no leakage. Fill the lower chamber with water up to about 0.5 cm below the safety valve, place evenly spread coffee grounds into the filter basket, then assemble and place it on the heat source. When you hear a distinct "wuu wuu" sound, reduce the heat and open the upper chamber lid. Once the coffee liquid has extracted to about half, turn off the heat and let the remaining extraction finish using residual heat.
Coffee made with a moka pot usually has a rich crema, a thick texture, and distinct layers. It is suitable for drinking straight or can be adjusted to personal taste by adding water or milk.
In a comprehensive comparison, PWN Golden Mandheling brewed with a French press showcases layers of spice, pine, chocolate, and caramel, with a dense texture and a light oily feel; whereas the moka pot enhances the aroma of roasted nuts, herbs, and dark chocolate, resulting in a more concentrated flavor with a pronounced sweet aftertaste. Both methods have their unique strengths, suitable for selection based on personal preference and context.
Regardless of which device you choose, mastering the correct grind size, water temperature, and brewing time is key to enhancing the flavor performance of your coffee. Beginners are advised to start with basic parameters and then fine-tune according to actual taste, gradually finding the brewing style that suits you best.
