When we buy a filter cup, we often see what 1-2 people, 3-4 people. The size and capacity of different filter cups have an impact on the amount of coffee powder. So, how should we brew coffee with different amounts of powder?

Let's take the washed [Yega Sheffivoka] as an example to do this demonstration.

Woka Cooperative, located in the south of Gedeb District, was founded in 2005, and joined the famous Yejia Coffee Farmers Cooperative Union (YCFCU,Yirgacheffe Coffee Farmers Cooperative Union) that year, which is famous for producing high quality sun Ye Jia Coffee Farmer. The Waka Cooperative has about 300 coffee farmers. YCFCU was founded in 2002 and includes 26 other cooperatives serving more than 45000 coffee farmers.

1 person

Usually rush 1 person, in the choice of filter cup, the ordinary 1-2 person cup can be. Usually we use 15 grams of powder, the ratio of powder to water is 1:15, the water temperature is 90 ℃, medium and fine grinding, the time is about two minutes.

Imported lemon acid notes, jasmine fragrance is obvious, the tail rhyme has a kind of lemon black tea feeling.

2 persons

If there is one more person, the amount of powder will be increased by 10 grams, that is, 25 grams. At this time, we have to choose a filter cup for 3-4 people. So for 2 people and the following 3 people, we all use key's 02 diamond filter cup to brew.

The ratio of powder to water is also 1:15 and the water temperature is 90 ℃. As the amount of powder increases, the cooking time will also increase, so it is necessary to thicken the grinding, that is, moderate grinding, for about two minutes and twenty seconds.

The acidity of flower, lemon and white grape juice is obvious, and the juice feels solid.

3 people

Try to use 30 grams of powder for cooking, although the choice of Key's No. 02 diamond filter cup, but it will be somewhat reluctant.

The degree of grinding we chose BG 6A, is a relatively rough grinding; a total of four stages of water injection, 40 grams of water steaming for 30 seconds, water injection to 160g water, 240g hours, 350g hours a section, the flow gradually increased, and finally the flood flow directly in the middle to 450g to the end of cooking, the time is about three minutes and thirty seconds.

The feeling of imported lemon tea is very obvious, with some honey-like sweetness!

The editor believes that in order to avoid over-extraction caused by the increase of extraction time, the editor believes that in order to avoid over-extraction caused by the increase of extraction time, coarse grinding can be chosen to slow down the speed of coffee extraction. in the end, increasing the water injection is mainly to reduce the concentration of the coffee liquid, while quickly extracting a small part of the substances that can still be extracted.
