What is the extraction time of espresso?
Work begins: first remove the brewing handle from the coffee maker. (need to pay attention to two things: first, always buckle the hand on the brewing head to keep warm, do not put it on the warm cup or plate or other places, otherwise the low temperature handle when brewing coffee will lower the temperature of the brewing water and cause the coffee to go sour. Second, the coffee grounds inside should not be deducted before brewing the next cup of coffee, because the copper cooking head at high temperature will produce a peculiar smell, and the coffee grounds can absorb the smell.)
Wipe the filter in your hand completely with a dry towel. It is absolutely necessary to keep dry in the filter. If there is water in the filter, the coffee powder will start the coffee extraction process before brewing, resulting in excessive extraction. In addition, it will also make the coffee powder agglomerate, resulting in uneven filling pressure. Also, dry the outlet of your hand to prevent the coffee powder from flowing into the cup.)
But if you really want to learn to make good coffee, you have to start from the origin and raw bean pretreatment to think about coffee beans, which is a slow stewing process with no shortcuts at all. Luyao has been systematically exposed to academic coffee for no more than a year, and his personal preferences have always been clear. He prefers hand-brewed coffee to traditional Italian style. "Italian coffee is mostly deeply roasted, and it is difficult to control the internal pressure and temperature of the coffee machine. It is greasy, and it is also the art of blending milk and coffee. On the other hand, the roasting degree of beans used in hand-made coffee is relatively shallow, although Japanese hand-made coffee still tends to be roasted deeply to reflect the imprint of the coffee maker, but I still like light roasting. The beans themselves retain a considerable degree of fresh flavor, which is a precious relic of the place of origin. "
