Water temperature: boiling water into the cool hand pot is basically about 95 degrees, at this time to grind beans (I use electric mill, hand or grind first …... As DIMLAU said, 95 degrees starts steaming, and when you flush, the water in the pot can start to flush at about 90 degrees. Basically, the water temperature is always in the right state, and you don't have to worry about it without a thermometer.

Powder-water ratio: for those who are too lazy to understand the golden cup, please read the boldface directly. Citing the rule of the fool's version of the golden cup (temporarily based on the American version of the gold cup, based on the average concentration and average extraction rate of American black coffee drinkers' favorite range of nearly 10,000 random samples), the data is 1.15% to 1.35%, and the extraction rate is 18% to 22%. In the stupid version, then what can we control? The ratio of powder to water, the mid-point recommended brewing ratio of SCAA's golden cup rule is 1buzz 18.18SCAE midpoint 1RV 16.6666666, but due to the diversity of brewing methods, and when the roasting degree of modern boutique coffee is generally not deep (not easy to extract) or pay more attention to the extraction of sweet and sour front flavor (tend to low extraction rate). For example, the use of bypass (a large amount of powder is extracted before the flavor is injected into the appropriate concentration), so the average extraction rate is not enough, so it is recommended to use 1:16 (1 g coffee powder corresponds to 16ml water). Under this powder-to-water ratio, the extraction rate is relatively low and it is easier to reach 1.15%-1.35% concentration.

Xiao he is to blame for the so-called success or failure. If we take advantage of the characteristic that the metal screen will let the fine powder pass through, our French pressure will become a professional coffee press filter pot, and all we need to achieve this step is a detailed metal screen (fineness is based on Hario's TH series filter press, if you can buy that kind of filter pot that can see the mesh clearly with the naked eye, please buy some good tea to make it) and an ordinary coffee mill: domestic Pegasus. Swiss-made solis166/167 and high-quality hand mill can be competent. The degree of grinding should be slightly thicker than spinning sugar, so that the degree of grinding is basically close to the limit of ordinary coffee grinding (another case for changing the machine), and then the ground coffee powder will be carefully sifted with the pleasant dry aroma. Do not pity the fine powder that floats away, it is a poisonous powder that destroys the quality of coffee, and you do not have to sift it for too long so as not to affect the freshness, of course, if you use fresh beans baked within 2 weeks. All efforts beyond this deadline are in vain. But at least you can get a cup of black liquid that is easier to enter than before. of course, the French pressure is not perfect, and the problem that the metal filter can not completely filter the fine powder is one of the problems, so there is the view that the French pressure requires rough grinding. it is true that coarse grinding can reduce the content of fine powder to a certain extent. But the price is that the particles get thicker and much of the content cannot be extracted. Based on this, there is a point of view that it is necessary to increase the extraction time to improve the extraction rate. However, the effective extraction temperature range of each kind of bean is very narrow, there is no heat preservation function of the French pressure, only tens of seconds is in the effective extraction. At the same time, because the fine powder could not be completely eliminated, after several minutes of soaking, they were thoroughly over-extracted, bitter, astringent and miscellaneous tastes gushed out one after another, so a cup of coffee that can only be used to entertain the sink was born.
