Flannel hand-made iced coffee shows the maximum flavor of coffee.

The supply of hot coffee for many people can be prepared in advance. When brewing, we must pay attention to the skills such as coffee powder thickness, water temperature, water quantity and brewing method. It is best to use a sharp-mouthed kettle, which has a better effect. At the same time, after the coffee liquid drips, we must return the temperature to 80-90 degrees Celsius in order to achieve the best drinking flavor.

(1) preparation utensils: triangular flannel bag, iron frame, kettle, coffee spoon, pointed kettle, cup with capacity scale.

(2) Coffee beans: coffee beans that are lightly roasted.

(3) Coffee powder dosage and grinding degree: 15-20 grams per person, coffee beans can be increased or decreased according to the preferred taste (grinding degree: moderate). The thickness can be adjusted according to individual taste.

(4) Water volume: 150-200ml. Remind you: coffee powder will swell after ◎ boiled water is injected, so choose a slightly larger strainer. The flannelette side of the ◎ filter is on the outside, fully wring off the water and straightening the wrinkles before use.

(5) step ① pours the freshly ground coffee powder into the flannel filter. Flannel has two sides, one is a flat fiber pattern, and the other is a soft flannelette, which is used inside and outside. ② dug a hole in the coffee powder (for the size of the hole, please refer to the filter paper), then filled with hot water for the first stew. After 30 seconds of ③, water was injected again and steamed for the second time, which was also 30 seconds. Because the flow rate of flannel is faster than the other two filtration methods, in order to prevent the soaking time from being too short, the coffee extraction is insufficient, so one more stew is carried out. ④ begins to inject water continuously, using the same filter paper procedure. ⑤ immediately removes the filter cup as soon as the coffee reaches a sufficient amount to complete the whole brewing action.

(6) safekeeping of flannel filter: when using a new flannel filter, in order to remove the water paste or smell that may be left on the cloth, use a brush to wash (do not use soap or soap powder at this time, because the taste cannot fall off). Boil the used coffee powder with water for 5 minutes before washing with water.

(7) the preservation method of flannel filter: wash the filter cloth well with water after use, and put it in the cold storage to prevent oxidation. And the water must be changed every day, otherwise the scale will cause clogging of the cloth. When in use, brew it at a warm temperature, then fully wring it out and then use it.
