Gouache proportion of coffee brewing reference-drip coffee pot gouache ratio

Determine the amount of coffee to be brewed and set the upper and lower limits of coffee powder from the control table, how to reach the best extraction rate from 0: 30% to 18: 22%, and the brewing concentration of coffee is just at 1.2%-1.45%, just like how to throw a good ball. After brewing a cup of Gold Cup coffee, the above basic powder and brewing amount are determined, whether it can reach the best extraction rate of 18%-22%, while the concentration falls at 1.2%-1.45%, which involves the problem of extraction rate, coffee grinding thickness, water temperature, filter medium (affecting water retention time). Wait for mutual cause.

According to SCAE, the controlling factors of making a good cup of coffee include the following five items; no matter how you brew coffee, these five principles must be mastered.

Master extraction time Contact time: apply various brewing methods, in order to extract 180.22% extraction rate within the better extraction time, it is important to control the grinding degree and water temperature of coffee.

It is necessary to master the water temperature from Temperature of the water:92 °C to 96 °C. too high or too low initial water temperature may not be appropriate.

Disturbance of coffee powder Turbulence in the process of brewing: disturbance is to get the proper extraction rate, such as plug air stirring, hand flushing water column flushing strength and so on are all necessary to achieve the extraction.

Pre-soaked moisturizing coffee powder Wettability: hand-made, espresso, American style has the same wetting stage before brewing, this stage wetting water is per gram of coffee powder, 2ml water pre-soaking, soaking time is about 30sec. Of course, the roasting state of coffee beans has different pre-soaking and moistening states, and this part of the hand washing can be well controlled.

In Italy, you often see people walk into a cafe, order a cup of Espresso that is only about 30 milliliters, pick it up, drink it, and then go out. Yes, the right way to drink this thing may be more like wine. Some even choose Ristretto with only 15ml (also known as super-espresso in China).

The scale is right, but the brewing proportion is not right, and it is not easy to make delicious coffee. In the process of learning, we need to drink repeatedly and test the concentration. It is found that the best brewing ratio, that is, the amount of coffee beans is higher than that of black coffee, which is between 1 cup, 12 grams and 13 milliliters, which is equivalent to the four major gold cup systems in Europe and the United States. the yield of coffee beans is 14.5 grams 115.5 per gram of raw water, and it is most likely to hit the golden range of 18% 22% and 1.15% 1.35% of the "golden cup moment". Instead of brewing espresso with tangled flavor spectrum or thin coffee with too strong water flavor. It is believed that the brewing ratio of most hand-brewed coffee lovers should fall within this range. The most commonly used hand-brewing ratio in Chongqing is 1: 12: 1: 13, that is, 1: 14.5: 1: 1: 15.5 according to the Golden Cup Criterion. 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.
