Degree of grinding of siphon pot what is the degree of grinding of siphon pot

The process of flavor extraction and filtration is carried out at the same time, and the extraction takes place around the position where the water is poured into. The more water, the more extraction. Newly roasted coffee beans will produce more carbon dioxide, these gases are not conducive to the full contact between water and coffee powder to complete the extraction, so it is necessary to stew first to avoid uneven extraction of coffee powder and affect the efficiency. The principle of extraction is that the coffee ingredient enters the water from the surface of the coffee powder, and with the decrease of the surface concentration, the coffee component is transferred from the center of the powder to the surface.

Siphon coffee focuses on taste and aroma. Therefore, the grinding speed can not be too fast, too fast and easy to overheat, overheating will accelerate the volatilization of aromatic substances in coffee powder, nor too slow, coffee powder exposed to the air for a long time, of course more volatilization; to contact the progress of heating, master a degree, moderate grinding speed; generally after a few turns can be reversed

First, wash the filter cloth and tie it to the metal sheet, then pick up the pot, pull the small bead chain through the glass tube and pull it down until the small hook hooks under the glass tube to make sure that the filter cloth and the metal sheet are firmly fastened to the pot.

The change of humidity is also one of the factors affecting the degree of grinding. When the humidity is relatively high, the wet speed of the ground coffee powder is very fast, and there is already a slight humidity when filling the powder and cloth powder. If a fine grinding degree is used, the coffee flavor components have already reacted with the air with high humidity and become messy and impure, while the coffee powder is easier to be compacted and the extraction process is longer, which makes it easier to extract the bad taste and make the overall coffee taste muddy. Therefore, in the case of relatively high humidity, it is not suitable for a finer degree of grinding, it will be better to use a slightly thicker degree of grinding. On the other hand, in the case of relatively low humidity, coffee powder is ground out after contact with the air, the speed of oxidation reaction will also be accelerated, if the coarse grinding degree is used, then the coffee powder oxidation and flavor composition changes together make the extracted coffee taste will be less, lack of depth and mellow feeling, so the degree of grinding should be adjusted appropriately. Of course, after adjusting the degree of grinding, it is necessary to adjust the strength of pressing powder accordingly.

When the coffee beans are ready, grind the beans moderately, use the electric bean grinder to scale about 4, and the hand bean grinder is to adjust the slice from the bottom circle or so.
