Sumatra Mandheling coffee beans

 

Sumatra Mandheling coffee is a famous specialty coffee in Indonesia and one of the best-selling Indonesian coffee beans in Front Street ration beans. Indonesia is located in southeastern Asia. Its coffee history can be traced back to 1696. Dutch coffee farmers tried to find a wider coffee planting land. After many explorations, they finally determined the Java Island in Indonesia. After 30 years, Indonesia has laid a sufficient foundation in the coffee market. However, today, the representative of Indonesian coffee is Mandheling produced in Sumatra. This is actually not an unexpected result, because most of the Javanese coffee sold to Europe at the beginning came from Sumatra, and Mandheling came from Sumatra. Therefore, Sumatra can be said to be an important coffee producing area in Indonesia.

Golden MandhelingCoffee varieties


FrontStreet Coffee's new season golden mandheling is produced in GAYO Mountain in Aceh, North Sumatra. The variety is Ateng, which is a cross between Arabica and Robusta and is widely grown in Sumatra and other small Indonesian islands. Ateng is actually the local name for Catimor coffee. In 1959, the Portuguese moved the Brazilian Bourbon mutant Catura to East Timor and mixed it with Tim with Robusta ancestry. It has super high disease resistance and is three times the production capacity of Typica. During the leaf rust crisis, the Indonesian government not only introduced Robusta (its flavor is far different from Arabica), but also introduced Tim to East Timor, intending to replace Typica. After subsequent investigations by experts, it was discovered that a batch of Tim seeds introduced by the Indonesian government in 1980 were mixed with some Katim seeds. These seeds were planted in Aceh in northern Sumatra, and the first area where Katim was discovered in Indonesia was central Aceh, so the locals also called Katim Ateng, which is taken from Aceh. Tengah (Central Aceh).

Mount Acehgayo is at the northernmost tip of Sumatra. The coffee cultivation in Mount Gayoo is mainly around the town of Takegon and the hillside land next to Lake Tawa. The average height in the production area is between 1100 and 1600 meters. The quality of its coffee has always been excellent. However, due to the previous political instability, the coffee in this area was difficult to export. In recent years, the situation has been peaceful, and coffee planting in Aceh has also been developed, and the quality is better than that in Lindong.

 

Front Street PWN Gold MandhelingThe requirements for quality are even stricter. First, the size of the coffee beans must be 19 mesh, and the particles must be full and even. Next, they have to go through one machine selection and three manual hand selections to ensure the defect rate of the green beans. There is no doubt that this is a sign of trust in the quality of the coffee produced in the Aceh Gayyu Mountain region.

 

Golden Mandheling coffee processing method:

 

Front Street Mandheling CoffeeThe unique flavor is fundamentally related to the processing method. Due to Indonesia's sultry climate and lack of water sources all year round, Indonesian coffee farmers developed a method to better dry coffee beans while saving water - the wet planing method, also known as the wet hulling method.

So how do you hand brew the Front Street Golden Mandheling coffee beans?

 

There are light roasted and dark roasted coffee beans, and the notes on hand brewing are also different.Front Street Gold Mandheling Coffee BeansFor dark roasted beans, the water temperature should not be too high, so use a Kono cup. The water temperature is low because we don’t want to extract too many impurities. When FrontStreet Coffee chooses dark roasting, too many aromatic substances have been released. If you continue to use light roasting water temperature for extraction, it will lead to over-extraction. The reason why FrontStreet Coffee chose the Kono filter cup is because the flow rate of the V60 filter cup is too fast and under low water temperature conditions, it is easy to under-extract. The Kono filter cup has few ribs and is located at the low end. The filter paper is close to the filter cup, which can limit the air flow, increase the contact time between water and coffee powder, allow the coffee powder to be fully extracted, and enhance the mellow taste.

Parameters of Front Street Brewing Front Street PWN Golden Mandheling Coffee:

 

Water temperature: 88°C, powder amount: 15 grams, powder to water ratio: 1:15, grinding degree: medium to fine grinding (pass rate of No. 20 sieve 70%).

 

Using segmented extraction, use 2 times the amount of coffee powder for steaming, that is, 30 grams of water is steamed for 30 seconds. The reason why the steaming process is required is to allow the coffee powder to discharge the internal carbon dioxide gas, thereby making the subsequent extraction more stable. Use a small flow of water in a circle to inject water in stages until 125 grams is reached. Continue to inject water until 225 grams and stop. When the water in the filter cup has finished dripping, remove the filter cup. Start timing from the water injection. The extraction time is 2'00'. Next, pick up the entire cup of coffee, shake it evenly, and then pour it into the cup to taste.

Of course, there are also some customers who need Front Street’s help in grinding the powder, which is okay, but Front Street needs to remind you: if the coffee beans are ground in advance, there is no need to raise the beans, because during the transportation process, the pressure generated by the carbon dioxide in the packaging can also make the coffee flavor mellower, so you can make a cup of coffee immediately after receiving the coffee powder. But the coffee powder needs to be brewed in time, because the coffee powder oxidizes quickly when exposed to air, which means that the flavor of the coffee will dissipate relatively quickly, and the flavor of the coffee will not be so good. Therefore, Front Street recommends buying whole beans and grinding them freshly, so that you can better taste the flavor of the coffee.
