Professional coffee knowledge exchange more coffee bean information please follow the coffee workshop (Wechat official account cafe_style)

Basic equipment

A hand flushing pot, a filter cup, a filter paper, a coffee pot, a thermometer, a bean grinder, a measuring key, a scale

Key concept

1. the ratio of coffee powder to water is 1:17

2. The temperature is 90-95 degrees Celsius.

3. Stable uniform extraction

4. The extraction rate is 18%-22%.

Manual step explanation

1. Measure the weight of coffee beans, a cup of about 10 grams, brewing 170cc about; two cups (about a mug) about 18 grams, brewing about 300cc, can be adjusted according to personal taste. For each additional cup, the coffee powder increases by about 7 to 10 grams. Then grind it moderately, and the coffee powder particles are similar to those of No. 2 sugar.

2. Add hot water to the appropriate amount of water in the hand flushing pot and insert a thermometer. Use hot water of 90 degrees Celsius to 95 degrees Celsius. Basically, the water temperature should be changed according to different baking degrees of beans. The deeper the baking, the lower the water temperature.

3. Pour hot water over the installed filter paper, warm the cup and the kettle, dilute the smell of the filter paper (some filter paper will contain chemicals such as bleach), and then pour out the water from the coffee pot. Of course, if the filter paper does not smell or bleach, you don't have to get wet first. The purpose of the warm pot is that when making coffee, the temperature of the coffee will not lose temperature too fast.

4. Pour in the coffee powder and pat the filter cup to smooth the coffee powder.

5. at the beginning of the first water injection, the water column should be stable and allow a small amount of hot water to flow out of the nozzle, not too large or too fine. The distance between the beak and the powder layer is about 6 cm, and the force should be maintained and the speed should be the same. Don't be too fast, let the hot water feel like a "light up", circle from the center to the outside, and stop pouring water as soon as you get close to the edge, so that the coffee powder is soaked. Then rest for about 30 seconds, which is called steaming.

6. wait until the end of steaming, start the second water injection, circle from the central point, from the inside to the outside, and then from the outside to the inside, repeat and stabilize this action until the required amount of extraction is almost reached. By the way, remember to keep the water column from touching the filter cup wall when injecting water.

7. Pour into a cup that has been warmed in advance and begin to taste and taste.

Clean up after the event

Just pour out the filter paper along with the coffee grounds, and then wash the filter cup and coffee pot with water.
