Last Updated: 2024/11/03, At the same time, in addition to the exhaust of gas from the interior of the coffee powder, hot water also slowly penetrates into the interior of the coffee powder, causing some soluble substances in the coffee powder to begin to dissolve and form a high concentration of coffee liquid. At the end of the steaming process, the overall temperature drops as the gases are exhausted, and some of the unexhausted air begins to contract slightly

How to fold the hand-brewed coffee filter paper? should I cut the filter paper?

At the same time, in addition to the discharge of gas from the inside of the coffee powder, hot water also slowly seeps into the inside of the coffee powder so that some soluble substances in the coffee powder begin to dissolve and form a high concentration of coffee liquid.

In the final stage of steaming, because the gas is almost discharged, the whole temperature decreases, and some undischarged air begins to shrink slightly, so from the outside, the hill will gradually dry or slightly crack and collapse, which also means that the steaming is complete and the second water injection can be started.

When injecting water for the second time, the high concentration of coffee liquid dissolved first during steaming will move to low concentration hot water. In the whole brewing process, due to the continuous pouring of hot water and the constant dripping of coffee, the concentration of coffee powder inside and outside will be different. This is also the reason why the coffee will be stronger at the beginning and lighter in the second half.

1. Grind coffee beans, because hand-made, coffee bean powder should not be ground too fine (20g beans = 300ml original solution).

two。 Fold the filter paper into a triangular funnel.

3. Put the folded filter paper into the filter cup and wet it with hot water. on the one hand, it can remove the smell from the filter paper, and on the other hand, it can warm the cup to prevent coffee from suddenly turning sour (note: pour out after filtering water).

4. It's steaming. Grind the coffee and pour it into the filter paper. when the hot water cools, pour hot water from the top of the filter cup and the water will not pass the powder.

5. Continue to inject water, draw a circle from the center to inject, the flow is fine and slow, and the extraction is sufficient.

6. When you reach the amount of coffee liquid extraction, remove the filter paper immediately.
