Some friends bought FrontStreet CoffeePWN Gold Mandheling Coffee BeansLater, I asked Front Street, "Why does the taste I brew at home differ from what I drink in the store? I have scanned the QR code on the coffee bean packaging and looked at your parameters for grinding and brewing. Why do I feel like something is missing after brewing it?" Don't worry! FrontStreet Coffee uses Kono's famous filter cup to brew golden Mandheling coffee beans. The biggest feature of this filter cup is that it can enhance the mellowness of the coffee, so the grinding degree in the parameters will be slightly coarser. Many friends use the V60 filter cup to brew golden Mandheling coffee beans at home, so how can I use the V60 to brew it?PWN Gold Mandheling CoffeeHere~

What is the difference between kono famous filter cup and V60 filter cup?
The V60 filter cup is a large hole filter cup and is characterized by fast flow rate. The design extending to the low ribs and large holes allows the barista to have sufficient room to control the flow rate. For example, during the early stage of brewing, the flow rate can be reduced to fully extract the flavor substances in the front stage, and the flow rate in the later stage can be accelerated to reduce the production of bitter substances. FrontStreet Coffee believes that the coffee brewed by the V60 filter cup has a good sense of layering.
The Kono filter cup is a small hole filter cup, and its characteristic is slow flow rate. There are only short ribs close to the orifice, and the cloth powder without ribs is in close contact with the filter paper. There is no space for air to flow, the extraction speed will be slowed down, and the water-powder contact time will be longer than that of the V60 filter cup. Front Street believes that brewing with Kono's famous filter cup can improve the mellowness of coffee, so this filter cup is always used when brewing medium roasted coffee beans.
Back to the topic, the Front Street Kono filter cup is used to brew PWN Gold Mandheling coffee.Grinding degreeBrewing with V60 will feel thin, so how should we adjust it?
First, let’s review the kono brewing parameters provided by FrontStreet Coffee PWN Golden Mandheling: powder volume 15g, powder-to-water ratio 1:15, water temperature 88°C, grinding degree: medium-coarse grinding (0.85mm aperture screen sieve rate 65%). Seeing this, are you thinking about what a 0.85mm aperture screen is?
The purpose of the 0.85mm screen is to determine a grinding calibration standard suitable for the brewing method of this coffee bean. First, weigh 10 grams of coffee beans, then grind the coffee to the degree of grinding to be measured, then place the ground coffee powder into the upper part of the sieve, and shake vigorously to drop the coffee powder with a thickness of less than 0.85 mm into the lower part of the sieve. Shake multiple times and continuously to ensure that all coffee powder smaller than 0.85 mm falls out. At this time, weigh the lower part of the coffee powder and divide the weighed coffee powder weight by 10 grams to get what we call the sifting rate.
Front Street has carried out different sieving and multiple experiments on the grinding thickness of coffee brewed in various ways. The final recommendations for black coffee brewing grinding thickness based on 10g coffee powder sieving are: ice drip > light roasted hand brew, Psiphon sieving rate 80% > Mocha, American drip sieving rate 75-80% > cupping sieving rate 70-75% > Medium roasted hand brew, French press, sieving rate 65-70%. FrontStreet Coffee's PWN Golden Mandheling uses medium roasting, so when brewing, the amount of coffee powder passed through 10g of coffee powder reaches a thickness of 6.5g-7g, which is about the size of coarse sugar.
So sinceGrinding degreeWe didn’t adjust it above, but used the V60 filter cup to brew. What should we adjust?
When it is not recommended to adjust the grinding degree, then you need to adjust the water-to-powder ratio for coffee brewing! The ratio of powder to water brewed by Front Street using the kono filter cup is 1:15. Because the kono filter cup is characterized by slow flow rate and increased mellowness, this parameter is just right for brewing with the kono filter cup. So for the V60l filter cup, which has the characteristics of fast flow rate and high layering of brewed coffee, Front Street recommends using a ratio of 1:13, so that the coffee can improve the overall body of the coffee by reducing the ratio of powder to water.
When brewing PWN Golden Mandheling coffee with V60, do I need to adjust the brewing water temperature?
Here Front Street recommends using 90° water temperature. Higher water temperature will release the flavor molecules of the coffee faster. Coupled with the fast flow rate of V60, the coffee flavor of PWN Golden Mandheling coffee can be more mellow. One thing to note is that when using a water temperature of 90°C, you must ensure that the grinding degree of the coffee powder is still at a screening rate of 65%-70%. If the grinding is too fine and brewed at this temperature, the coffee will taste bitter/woody and other miscellaneous flavors.
Having said so much, let’s finally summarize the parameters of V60 brewing golden Mandheling coffee beans!
Powder amount: 15g
Pink to water ratio: 1:15
Grinding degree: medium-coarse grinding (Chinese No. 20 standard sieve screening rate 65%-70%)
Water temperature: 88℃
Use three-stage extraction: in the first stage, use 30g of water to fully wet the coffee powder layer and steam it, then inject 70g in a circle with medium-fine water flow (the total weight is 100g at this time), and wait until the liquid level drops to 2/3 of the coffee powder layer. Start the third stage of injection. Use medium-fine water flow to evenly inject 95g in a circle and then stop injecting water. The total injection amount is 195g. The final extraction amount of coffee is 170g. The extraction time is 1'45".
Because the coffee brewed by the V60 filter cup has distinct layers, after the coffee extraction is completed, it must be shaken thoroughly before tasting.
