When coffee becomes a part of life, hand-brewing coffee becomes a concrete manifestation of the ritual of life. From the selection of coffee beans to the grinding of coffee powder, and then to the brewing process, the selection and operation of each link will determine the final flavor and temperature of this cup of coffee.

Ratio of coffee powder to water

It is believed that the brewing ratio of most hand-brewed coffee lovers should fall within this range. Our most commonly used hand-brewing ratio is 1-15-15-1-16, that is, the "golden cup" criterion of 1-15-1-1-1-18. 5.

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 the 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, and it is too wasteful of coffee powder to be encouraged. In fact, a better coffee can be made at a more normal 1:12 (that is, a golden cup ratio of 114.5%).

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 taste is too dull and depends on high concentrations to stimulate it.

Many coffee lovers are good at making coffee for one person, but they will be at a loss if they increase the number of people. Some people say that one more person will multiply by two, and some will use 2 grams less powder for each additional person. In other words, if one person brews a cup of 180 ml coffee with 14 grams of powder, once it is increased to two, only 26 grams of powder (saving 2 grams of powder) can be brewed twice as much, a total of 360 milliliters of coffee.

The extractable water-soluble ingredients of coffee beans account for at most 30% of the bean weight, and coffee from some producing areas 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 by hand in the same period. The amount of coffee powder will not increase because of the increase in the number of cups, and there is room to reduce the amount of coffee powder. The concentration of coffee powder can be determined by itself, unless you brew it with finer coffee powder or higher water temperature, which is another matter.

Production time

Hand-brewed coffee does not take long to make, from preparation to the end of extraction may be about 5 minutes, 5 minutes can make a cup of coffee with good flavor, no wonder it is loved by so many people.
