Introduction to the treatment method of Grinding degree in producing areas of three key words of hand-made Coffee

Hand-made coffee

Step 1: fold the filter paper and put it into the filter cup.

Hot water filter paper

Step 2: rinse the filter paper with hot water, just let the filter paper wet completely, so as to remove the smell of the filter paper. (although there is only a little water to wash the filter paper, don't forget to pour it out first and then take follow-up actions.)

Coffee powder rubbing a small hole

Step 3: pour in the coffee powder, distribute it evenly, and rub a small hole with your little finger in the center.

Pour hot water into the hole

Step 4: with 87 to 92 degrees hot water, first pour some hot water into the small hole, then slowly spread to the surrounding coffee powder clockwise or counterclockwise, until the water is dripping and steam for 30 seconds. (steaming allows coffee powder to inhale hot water and discharge carbon dioxide, which is helpful for the extraction of aromatic substances.)

Coffee powder will swell and bulge

Step 5: when steaming, the coffee powder will swell (the fresher the coffee powder is, the more it will bulge), until the bulge is about to collapse, it can be injected with hot water.

Spread in an intermediate circle

Step 6: when flushing by hand, take the middle as the center and slowly spread out in a circle, so that the hot water can be diffused horizontally in the coffee powder to extract rich coffee flavor. (do not rush directly to the outermost ring when making a circle, this will cause the hot water to fall directly along the edge of the filter paper cup, which will not only fail to extract, but will dilute the coffee concentration.)

Stir coffee powder with hot water under pressure

Step 7: raise the pot slightly before the end of the hand, shake the pot in the middle of the coffee powder, increase the brewing pressure, stir the coffee powder with hot water pressure, and do the final extraction before the end.

Let the water in the filter paper drip slowly

Step 8: collect the water, let the water in the filter paper drip slowly, and so on when you like the coffee in the proportion of powdered water, you can pick it up and enjoy it.

How to choose filter paper and filter cup?

Flannel can extract more aromatic substances

(1) Coffee filter paper is sold in many places. It is recommended to choose unbleached brown filter paper and wash it slightly with hot water before brewing. UCC, Tiamo, Kalita, Hario, pearl horse and other brands are the love of many coffee fans.

(2) generally speaking, the filter cup can be divided into two types: cone-shaped filter cup and ladder-shaped filter cup. the flow rate of cone-shaped filter cup is fast and the extraction time is short, so it needs better technology to control. Beginners, it is suggested that the ladder-shaped filter cup should be used to brew first. Hario, Kalita and Tiamo are all good brands.

(3) apart from the filter paper, there are metal strainer and flannel to choose from. The metal filter can flush out the oil of the coffee, and the flannel filter cloth can extract more aromatic substances because it has been filtered for a long time, and the taste is stronger.
