Mandheling coffeeIt is one of the most famous specialty coffees in Indonesia. What is special about it is that the coffee has a unique herbal aroma. Some people say it is like cigars, some say it is like spices, and some say it is grass. A friend told Front Street that he made it at home.Mandheling coffeeIt has only a bitter taste and no aroma at all like when you drink it in a store. So here at Front Street, take the Golden Mandheling from Front Street as an example. Let’s talk about how to make that Mandheling taste better.
Prepare a pack of freshly baked goods firstGolden Mandheling coffee beans
Before brewing, Front Street will first confirmGolden Mandheling coffee beansIf the roasting date of coffee beans is more than one month old, Front Street will not use it to produce coffee beans. Since coffee beans have an optimal tasting stage after roasting, the aroma of coffee will be lost at an accelerated rate with storage time, and the dissipated flavor is difficult to restore during brewing. This is why Front Street insists on only shipping freshly roasted coffee within 5 days. Front Street hopes that every customer can enjoy the most complete tasting stage of coffee beans.
front streetGolden Mandheling CoffeeProduced by the famous PWN company in Indonesia, it is processed by wet planing method. Although the wet planing method greatly improves the defect rate of coffee beans, the coffee taste is not particularly negative, but brings a herbal aroma. The final drying step of the wet planing method is not protected by parchment, so the green beans are directly exposed to the environment and are susceptible to the growth of various bacterial species. Give Indonesian coffee a unique aroma of wood, spices and herbs. This is what we call the "flavor of place".
Since the wet planing method uses "rough" friction to forcefully peel off the sheepskin when the beans are semi-dry, the production process requiresMandhelingThe green beans are subjected to a large squeezing force, and the green beans are deformed and even broken. Therefore, the wet planing method makes Mandheling green beans have a higher defect rate.
PWN Company invests a lot of manpower in green coffee beans. First, it only purchases G1 grade from the Tawa Lake area in the Gaio Mountains in northwest Sumatra.Mandheling coffee, and then undergo four manual screenings to ensure that the Mandheling coffee beans are uniform in color, shape and size. Therefore, PWN Golden Mandheling will taste cleaner and more translucent, and its mellowness and sweetness will be more obvious. (Green coffee beans with a mesh size of more than 18 and less than 3 defective beans in a 300g sample are classified as G1, which is the highest grade of Indonesian green beans).
In order to present the classic mellow flavor of Mandheling coffee, Front Street roasters choose medium-to-dark roasting to make the aroma of dark chocolate and caramel more explosive. FrontStreet Coffee baristas also adjust their brewing based on the roasting degree and flavor type of the coffee beans.
Pink to water ratio
For a cup of coffee produced by Front Street, 15g of coffee powder is used. The amount of powder is usually selected based on the size of the filter cup. The filter cup of Front Street is suitable for 1-2 people, and can be between 15-20g of powder. Excessive amount of powder is difficult to control, and the extracted coffee flavor is easily mixed.
Regarding the ratio of powder to water, 1:15 is the most commonly used, and the ratio range is from 1:13 to 1:17. If you like a rich taste, you can choose 1:13, and if you like something refreshing, you can choose a ratio of 1:17. Front Street believes that everyone has different tastes. 1:13 may be too strong for some people, and 1:17 may be too light, so we will take the middle value of 1:15.
The grinding degree should be coarser
Dark roasting loosens the internal texture of the coffee beans and can be crushed with a gentle pinch. This shows that the structure of the coffee beans has been changed a lot, and it is highly water-absorbent after being ground into powder. In order to avoid over-extraction of coffee powder after absorbing water and releasing a large amount of bitter substances, Front Street will use a coarser grind than light roasted coffee beans. Medium-coarse grinding will be used here (Chinese standard No. 20 screen pass rate 70%), store EK43s-scale 11.
The brewing water temperature should be lower
Roasting causes caramelization and Maillard reactions in coffee beans. As the roasting degree deepens, monosaccharides and amino acids interact and decompose under heating, causing more non-enzymatic browning, so it is easier to release bitter macromolecules. In order to avoid extracting too many impurities, Front Street will lower the water temperature a little. The brewing water temperature for light roasted coffee is 91~93℃, and Front Street recommends 87~88℃ for dark roasted coffee beans.
Choose KONO filter cup
FrontStreet Coffee baristas will give priority to KONO filter cups for brewing mellow-tasting coffee such as Indonesian Mandheling coffee, Brazilian Queen's Manor coffee, and Jamaican Blue Mountain coffee. Compared with the v60, the KONO filter cup has a smoother curved surface. This design is actually to ensure that the filter cup sticks to the wall of the filter cup after it is wet with water. At the same time, the guide ribs that are only a quarter of the height of the filter cup limit the air flow upwards, and the water can only pass through the bottom and remain in the pot. This will increase the time for the coffee powder particles to absorb water, allowing the coffee powder layer and hot water to form an immersion extraction, making the coffee taste more mellow and mellow.
Segmented water injection makes Golden Mandheling even sweeter
The brewing method uses a three-stage water injection method. The three-stage water injection can better express the mellow taste of golden Mandheling coffee and the sweetness of caramel.
Wet the KONO filter cup to make the filter paper and the coffee filter cup fit better. After draining the water from the pot, add 15g of ground coffee powder and steam it with 30g of water for 30 seconds. During this period of water injection, the coffee powder is fully wetted and exhausted, so as to better extract the flavor of the coffee later. When extracting light-roasted coffee beans, some friends extend the steaming time to 45 or 50 seconds to enhance the aroma of the first part of the coffee. However, if the dark-roasted Mandheling coffee is steamed for too long, it will easily release too much woody and miscellaneous flavors, so Front Street chooses to steam it for 30 seconds.
In the second section, start to slowly inject hot water with a small flow of water in a circle from the center, and keep the water flowing smoothly until the segmentation begins at 125g.
When the coffee powder layer drops to half of the filter cup and the powder bed is exposed, start injecting the second stage in the same way until it reaches 225g. When all the dripping is completed, the filter cup can be removed. The extraction time is two minutes, plus or minus 10 seconds. Finally, shake the next pot of coffee liquid and start tasting the Pour over(V60) golden Mandheling black coffee.
Ground Golden Mandheling coffee powder has the aroma of nuts and toasted bread, and the sweet aroma of caramel can be smelled during brewing. The brewed Mandheling coffee has spices and dark chocolate in the mouth. It has a mellow and clean taste, a clear sweet aftertaste, and a long-lasting aftertaste.
