Last Updated: 2024/11/17, Atmospheric pressure extraction, high pressure pre-soaking, what flavor of coffee 1. The coffee powder surface absorbs enough water without starting the extraction, and when the 9bar water is used to extract it, it increases the chance that all coffee powder particles can fully release aromatic substances. two。 When the coffee powder surface absorbs water and expands, the contact area between the coffee powder and the water distribution network of the coffee machine increases, and it is closer, reducing the extraction caused by uneven distribution of the powder.

Atmospheric pressure extraction, high pressure preleaching, what flavor of coffee

1. The coffee powder surface absorbs enough water without starting the extraction, and when the 9bar water is used to extract it, it increases the chance that all coffee powder particles can fully release aromatic substances.

two。 Coffee powder surface water absorption expansion, will increase the contact area with the coffee machine water distribution network, and more closely, reducing the probability of extraction failure caused by uneven distribution of powder. Of course, Viagra did not say that it is not good without a pre-soaked coffee machine, because it can make good coffee without a pre-soaked coffee machine.

The first is the choice of instruments for production. Good filter cups and filter paper are not only necessary for making good coffee, but also necessary for good steaming. The high-quality brand filter cup design groove can make the air fluidity is good, will not let the gas gush out from the coffee surface, the water permeability of the high-quality filter paper will also make the hot water pass through quickly, will not form the dripping filtration speed sometimes fast and sometimes slow.

Second, it is necessary to have a suitable hand flushing pot, which can well control the outlet speed and flow rate, flow rate, as well as the softness and hardness of the flow.

Third, water quantity. Steaming water does not need too much, only need to wet the surface of coffee, but need to be soft and light, fast and uniform, like spring rain moisturizer, so that the steaming speed can be carried out at the same time.

Fourth, the temperature of the water. I personally think that the best temperature for making hand-brewed coffee is 83 degrees, and the highest temperature should not exceed 90 degrees. This kind of water temperature will not produce too much bitterness or sour taste when steaming, and it can also make the coffee fully expand.
