Nowadays, many coffee-producing areas have more scientific cultivation, or more screening techniques to enhance the quality of coffee, and Mandheling coffee is no exception. For example, the front street of Indonesian PWN (Pwanni) CompanyGolden Mandheling coffee beans, it can be said that the highest grade Mandheling coffee in Indonesia is also the best representative of fine Mandheling coffee.


Front Street Golden Mandheling CoffeeWhy is it so famous?


front streetPWN Gold Mandheling CoffeeThe reason why it is the leader in Mandheling coffee is because PWN Company will use the Mandheling coffee beans purchased from the Acegayu Mountain production area in Sumatra, using 1 machine selection + 3 manual hand selections to ensure that the batches produced reach the highest grade of Indonesia, G1 grade. The purpose of machine selection is to first screen out beans whose specifications must be above 18 mesh. The subsequent multiple manual operations are to eliminate irregular and defective beans. The reduction of defect rate greatly improves the quality of Mandheling coffee.

It is mellow and the coffee is cleaner and sweeter, and the sweetness will be higher.


Where does Front Street PWN Golden Mandheling Coffee come from?


Indonesia mainly grows Robusta varieties, and the Arabica variety coffee production is less than one-tenth. Among them, the Mandheling coffee produced in Sumatra Island is the most famous, so it is also called Sumatra coffee. Traditionally, Mandheling in Sumatra is mainly produced in Lake Toba in the Lindong producing area of ​​Northern Jiangsu Province and Lake Tawa in the northernmost Aceh region.

Front Street PWN Golden Mandheling comes from Gayo Mountain (Gayo) in Lake Acetawa. The average planting height in the production area is between 1,110 and 1,600 meters. The coffee is grown by small tenant farmers under shade trees. The coffee beans processed by wet planing show a unique flavor and low and lively rich flavor.


Is Front Street Gold Mandheling dark roasted or light roasted?



Front Street noticed that in the past, Mandheling coffee on the market was all medium-dark roasted and had a classic, rich black coffee flavor. With the development of specialty coffee culture in recent years, everyone has begun to pursue a more unique coffee taste. Many businesses will launch medium roasted or even medium light roasted Mandheling coffee. The lighter the roasting degree, the more acidity the coffee beans retain. The flavor is mainly fruit, floral, and tea, and the body is lower. We might think, if the medium-light roasted Mandheling is so refreshing, why not roast it lighter?

I believe friends who often drink Mandheling should know the wet planing method in Sumatra. The wet planing is poured into the shelling machine before the final drying step. Large friction is used to tear off the semi-dry parchment layer that is close to the green beans. After the friction and stirring, the green beans are easily crushed or squeezed. The "naked beans" without the parchment skin dries very quickly. At the same time, they are directly exposed to a moist environment and are susceptible to the growth of various bacterial species.


Although wet planing does create a unique herbal and woody aroma for Mandhelingui, it also results in a higher defect rate in the green beans. Dark roasting can perfectly cover up this defect. In addition, Mandheling’s fame stems from the early discovery of the Japanese. Based on their taste preferences, there is nothing better than Japanese-style dark roasting. This is why most Mandhelings are roasted so darkly. Front Street hopes that everyone will drink the classic Mandheling taste, so the two Mandhelings sold daily on Front Street are medium-dark roasted, including Mandheling ration beans from Front Street Lindong production area and PWN gold Mandheling coffee from Front Street Aceh production area.

front streetPWN Gold Mandheling CoffeeHow to rush?


In order to allow the Front Street Mandheling coffee beans to express their mellow characteristics while also allowing the unique herbal flavor to be clearly displayed, Front Street Coffee (FrontStreet Coffee) roasts the Front Street Mandheling coffee beans before they come out close to the second burst, so it is a medium-dark roasting level. Good coffee needs to be freshly roasted. The coffee beans shipped by FrontStreet Coffee are shipped 5 days after the roasting is completed ~


When brewing PWN Golden Mandheling coffee, FrontStreet Coffee recommends using medium-coarse grinding (the size of coarse sugar, Chinese No. 20 standard sieve screening rate of 70%), a water level of 88 degrees Celsius, a powder-to-water ratio of 1:15, and a KONO filter cup.

The characteristic of the Kono filter cup is that the short rib design can slow down the speed of water flowing through the coffee particles, making the coffee taste fuller. The reason for using medium-coarse grinding is because as the roasting time of coffee beans increases, the structural density of the coffee beans will become greater and the release of substances will be easier. Therefore, dark roasted coffee beans require a combination of medium-coarse grinding and low water temperature for brewing. The KONO filter cup is suitable for medium-dark roasted Front Street Golden Mandheling.


Specific brewing techniques: Inject 30g of water for the first time and steam for 30 seconds; in the second stage, inject a small amount of water in a circle to 125g, wait until the water volume in the powder bed drops to half before adding water, and then continue to inject a small amount of water in a circle to 225g. After all drip filtration is completed, the total extraction time is about 2 minutes and 10 seconds.
