Front Street's products have always used filter cups that serve 1-2 people, and the powder quantity standard has always been controlled at 15g. Therefore, all of Front Street's manual brewing instructions are based on the brewing standard for 1 person (one cup). Recently, a friend asked me how to make 2-3 cups of coffee at once?
When the friend asked this question, it means that the friend already has some experience in brewing coffee for one person, and also discovered that brewing two more cups of coffee is not just as simple as adding more coffee powder.
According to the previous brewing standards, one cup of coffee contains 200ml (15g of coffee powder), so the amount of two cups is 400ml, and the required coffee powder is 30g. At this time, the No. 01 filter cup for 1-2 people will have difficulty functioning (the suitable amount of powder for the 01 small filter cup is 10-20g). If you want to brew more powder, you need to use a large filter cup No. 02.
Taking Hario's V60 filter cup as an example, the No. 02 large filter cup looks like an enlarged version of the No. 01 filter cup, which is suitable for brewing more than 20g of powder. Front Street has always emphasized the five major factors that affect coffee (amount of powder, proportion, grinding degree, water temperature, and technique). The factor that changed this time was the amount of powder, so we conducted a brewing around this variable.
Choose coffee beans according to your own taste. Those who are afraid of sourness should buy Front Street PWN Golden Mandheling and Front Street Blue Mountain No. 1 roasted to medium or above;
If you want rich taste, the first choice is Front Street Strawberry Candy and Front Street Colombian Claw with charming aroma;
For those who like fresh floral aromas, we recommend the medium-light roasted Front Street Fruit Tintin Cooperative, Front Street Kafa Forest, and Front Street Flower Butterfly.
Coffee Beans: Front Street Columbia · Divide Estate Hija
Powder amount: 30g
Pink to water ratio: 1/15, that is, 30/450
Grinding degree: No. 20 standard screen pass rate 80%
Water temperature: 91℃
Technique: Three-stage (60/190/200)
Filter cup: V60#02
The total extraction time was 2 minutes and 53 seconds. Only the filter cup and the amount of powder were changed, and everything else remained unchanged. The taste of 30g of powder was stronger and bitter. This happens because the extraction time is too long and the coffee is brewed out with a bitter taste.
During the brewing process, Front Street discovered that since the amount of water injected doubled, the time spent filling it with water also became longer. And although the drain hole of the large V60 filter cup is larger, blockage will still occur.
In this case, Front Street fine-tuned the parameters, because the coffee was soaked for too long, which made the coffee taste bad. Obviously, the ratio of powder to water and water temperature have little to do with this, so we have to start with the grinding degree and technique.
The amount of coffee is doubled, and the thickness of the coffee powder layer is at least 1/2 thicker. Then the water retention capacity of the thick powder layer will of course be stronger than that of the thin powder layer. Therefore, we need to appropriately adjust the grinding degree of the coarse coffee to ensure that their water retention capabilities are equivalent.
Another factor is the size of the water flow, which is a relationship between speed (size of water flow), time, and distance (amount of water injection). If the size of the water flow remains unchanged, if the total amount of water injected is more, the time taken will increase. If you want to control the variable of time, you need to increase the water flow.
Amount of powder: 30g Front Street Xizhao
Pink to water ratio: 1/15, that is, 30/450
Grinding degree: No. 20 standard screen pass rate 75%
Water temperature: 91 degrees Celsius
Technique: three-stage (60/190/200) water flow rate 7-8g/s
Filter cup: V60#02
This is a fine-tuned parameter. Through brewing practice, the extraction time is 2 minutes and 30 seconds. The taste is also on par with the one brewed for 1 person. Then some friends also asked, without the No. 02 filter cup, can the No. 01 filter cup also make a large amount of powder? The answer is: yes!
Although this time I only talked about how to make 30g of powder, I believe you are smart enough to learn to draw inferences from one example.
