The proportion of brewing does not decrease with the increase in the number of cups. It is fine for many coffee lovers to make coffee for one person. If you increase the number of people, you will be at a loss. Some people say that one more person will multiply by two. Some people will use less than 2 grams of powder for each additional person. That is to say, if one person brews a cup of 180ml coffee with 14 grams of powder, once it is increased to two. Only 26 grams of powder (save 2 grams of powder) can be brewed twice the amount of coffee, a total of 360 milliliters of coffee, coffee bean extractable water-soluble ingredients, up to 30% of the bean weight, some producing coffee may be even lower. Taste buds can talk, and the proportion of 1RU 13.8 without 2 grams of coffee powder is obviously thinner than that of 1RU 12.8. After ExtractMoJo test, the concentration of 1Rd 12.8 is 1.42%, which is significantly higher than 1.39% of 1RU 13.8. Therefore, under the same brewing ratio, the concentration of coffee will not increase naturally with the increase of the number of cups, that is to say, at 1:12, the concentration of one cup by hand is the same as that of two cups or three cups in the same period of the same period. The amount of coffee powder will not increase because of the number of cups.

Of course, some hand-brewed coffee lovers use a more extreme brewing ratio. For example, those who like heavy flavors are often hand-brewed at 1:10 (that is, the golden cup ratio is 1-12. 5), using a higher concentration to make up for the deficiency of extraction, that is, only to extract low molecular weight and medium molecular weight sour and sweet flavors to avoid extraction of high molecular weight bitter substances, although it can also make mellow delicious coffee, but the concentration is too high, it is not easy for ordinary people to accept. Moreover, it is a waste of coffee powder and should not be encouraged. In fact, good and mellow coffee can be made at a more normal 1:12 (that is, a golden cup ratio of 1mm).

Interestingly, there are also some light coffee lovers who like to brew by hand in a diluted proportion below 1:14, but do not underestimate these coffee lovers, whose taste buds may be sharper and can be appreciated in a variety of layers from the thinner coffee liquid. If you have to use 1:10 to brew in order to feel good enough, it may be that the sense of taste is too dull and depends on high concentrations to stimulate it.

1. Hand punch pot

Hand brewing pot is necessary for hand brewing coffee. When choosing a hand brewing pot, you need to consider "the stability of water flow, the heat preservation of the pot body and the safety of the handle". Different designs of the body and spout of different hands will bring different effects, the first condition is actually suitable for their own hands to hold, with accustomed to better control the flow of water, make delicious coffee.

2. Filter cup

Used to match the filter paper to filter coffee grounds, you can also directly buy the filter cup of the metal filter screen, the advantage is that you do not use the filter paper as a consumptive material, but it is a little troublesome to clean, and there is not enough room to adjust the cooking mode during the operation. Different brands of filter screen thickness will be different.

3. Sharing pot

Can be used to hold coffee, there is a scale to meet their preferences on the line, if not at least need to have a scale, because the powder-to-water ratio is involved.

Powder-to-water ratio, that is, the ratio of coffee powder to water, those that like lighter ones can be used at 1:18. Those who like thicker ones can be used at 1:15 in the middle of 1:13. Coffee tasting as a perceptual behavior, or need to be adjusted according to their own taste preferences.

4. Bean grinder

The grinding thickness and uniformity of coffee powder will affect the coffee in our hands, usually classified by the type of cutter head: flat knife, bevel knife, rail tooth.

No matter which kind can make good coffee, flat knife, rail tooth grinding is more uniform, extraction will be more uniform, cone knife cutting surface is different, will bring more layering. But do not choose a broken bean grinder, rather than a bean grinder, grinding is difficult to ensure uniform, the thickness is very uneven, will lead to the taste is too complex, sometimes there will be dirty feeling
