The ratio of hand-washed coffee beans to water

ratio of coffee beans to water

The brewing ratio does not decrease with the increase in the number of cups. Many coffee lovers are fine when making coffee for one person. If you increase the number of people, they will be a little confused. Some people say that the amount multiplied by two for each additional person. Some people use 2 grams less powder for each additional person. That is, if one person makes a cup of coffee with 14 grams of powder, once it is increased to two people, it only needs 26 grams of powder (saving 2 grams of powder) to brew twice the amount of coffee, totaling 360 ml. Coffee beans can extract water-soluble components, at most only 30% of the bean weight, some coffee may be even lower. Taste buds can talk, less than 2 grams of coffee powder brewing ratio 1:13.8, drink significantly thinner than 1:12.8, after ExtractMoJo test 1:12.8 concentration of 1.42%, significantly higher than 1:13.8 concentration of 1.39%. Therefore, under the same brewing ratio, the concentration of coffee will not naturally rise with the increase of the number of cups, that is to say, the ratio of 1:12, the concentration of the amount of hand-brewed cup, and the concentration of the same proportion of hand-brewed two cups or three cups, is the same; the amount of coffee powder will not increase because of the number of cups, and there is room to reduce the amount of powder, how much powder can be rushed out of the coffee, its concentration has its own fixed number, unless you use finer coffee powder or higher water temperature brewing scale to catch the right, but the brewing ratio is not right, it is not easy to rush out delicious coffee. In the process of learning, repeated trial drinking and concentration detection are needed, and the optimal brewing ratio of hand brewing is found, that is, the coffee bean ratio is between 1:12 and 1:13, which is equivalent to the four gold cup systems in Europe and America. The coffee bean gram ratio is 1:14.5~1:15.5 of the raw water volume. It is the easiest to hit the gold range of 18%~22% extraction rate and 1.15%~1.35% concentration, without making strong coffee or thin coffee with too heavy water taste. It is believed that the brewing ratio of most hand-brewed coffee lovers should fall within this range. The most commonly used brewing ratio in Chongqing is 1:12~1:13, that is, 1:14.5~1:15.5 of the "Golden Cup Standard". Of course, some coffee lovers use extreme brewing ratio, for example, like heavy taste often 1:10 to hand brewing (that is, the ratio of 1:12.5 gold cup), the use of higher concentration to make up for the lack of extraction, that is, only to extract low molecular weight and medium molecular weight sweet and sour taste, avoid extraction of high molecular weight bitter substances, although it can also brew a mellow delicious coffee, but the concentration is too high, most people are not easy to accept, and too much waste of coffee powder, not worth encouraging, in fact, with a normal 1:12 (that is, the ratio of 1:14.5 gold cup) can also brew a very mellow good coffee. Interestingly, there are also some light coffee lovers who prefer to brew at a diluted ratio of 1:14 or less, but don't underestimate these coffee lovers, whose taste buds may be more acute and can appreciate the layers of fragrance from the thinner coffee liquid. If you have to use 1:10 to brew, just feel enough flavor, it may be too slow taste, need to rely on high concentration to stimulate taste
