Humidity factors play a role not only in sunny and rainy days, but also at different times of the day. Generally speaking, the humidity in the morning and evening is higher than that at noon, so according to the influence of humidity factors, the grinding degree should be thickened in the morning and evening, and finer at noon.
There are many other factors that affect the degree of grinding, including the roasting degree of coffee beans (although coffee beans used by Espresso should use a deeper roasting degree, but sometimes different roasting degrees may be used to roast formula beans for richer taste), blended recipes, and so on. All of the above are the most common and can be mastered by baristas. The previous sections are all about the adjustment of the basic factors in the production process in order to meet that taste standard on the premise of understanding the good taste of Espresso (see the taste of Espresso). There are many places in the world of Espresso that we don't fully understand, and we would like to explore this wonderful world of coffee with you.
This electronic temperature control, with a chip, sets the temperature to stop by itself, and has the function of heat preservation, the ergonomic design makes it feel light when holding, and the new version of the limited flow valve in the kettle can better control the flow of water.
Roughness is a good way to control bitterness, because the finer the grinding, the higher the extraction rate, the easier it is to extract high molecular weight bitter substances such as chlorogenic acid, quinic acid, caffeine and carbides. On the contrary, if the grinding is too rough, the lower the extraction rate is, the more difficult it is to extract the astringent bitter substance with high molecular weight, but the sweet taste with middle molecular weight may remain in the coffee grounds because of insufficient extraction, which is a waste. Therefore, baristas should pay attention to whether the thickness of the powder is normal every day. Too thick or too fine will cause abnormal extraction and affect the flavor of coffee.
The degree of grinding of all kinds of bubble cooking methods, from coarse to fine, in the following order:
French filter kettle (rough grinding), electric drip pot (medium), hand punch, siphon pot, desktop smart filter cup (medium), mocha pot (medium), espresso (fine), Turkish coffee (very fine).
According to the European Fine Coffee Association (SCAE-Speciality Coffee Association of Europe), the rough grinding of the French filter pot indicates that each bean is crushed into 100,300 particles, each about 0.7mm in diameter. In the medium rough grinding of the electric filter pot, each bean is ground into 500 grains of 800 particles, with a diameter of about 0.5 mm. Moderately ground by hand and siphon, each bean is ground into 1000 to 3000 particles with a diameter of about 0.35. The fine grinding of espresso in which each bean is ground into 3500 particles with a diameter of about 0.05mm. Turkish coffee is ground into a flour-like ultra-fine powder, and each bean is ground into 15000mm 35000 particles.
