Hand brewing coffee operation process is as follows:

Materials/tools: filter cups, glass pots, coffee powder.

1, warming appliances, using a trace amount of hot water, to the filter cups and glass jugs of the "warm pot". Let the temperature of the coffee utensils to raise.

2, warm the filter paper, the filter paper into the filter cup, the first simple hot water to wet the filter paper (filtered out of the hot water poured out), so that the next to be brewed to retain the original flavor of the coffee.

3, add the coffee powder, the amount of coffee powder needed to hand brew into the filter paper, generally believe that hand brewing coffee powder grinding degree similar to the sugar like coarse and fine is appropriate. However, in reality, the thickness of the ground coffee depends on personal preference, and there is no certain guideline. For beginners, take 10 grams of ground coffee as an example, and brew it with about 180 ml. Then vary it until you find your favorite ratio.

4, water injection and stewing steam, "boring steam" (Bloom, that is, "bloom"). It is the beginning of the hand-brewed coffee, first with a small amount of hot water (about two times the weight of the coffee powder water) will be ground coffee powder wet, in order to make the coffee powder bubbling and expansion. The brewing method is to make a circle from the center outward. At this point, the ground coffee will form a hamburger shape and continue to expel air outward. When the expansion ends and begins to crumple, it means that the steaming is complete.

5, the second paragraph of water injection, "boring steam" step has actually been counted as a paragraph of water injection. Next, still from the center to the outside of the circle, slowly injected 100g of water, pay attention not to make the water level more than the edge of the coffee powder. At this stage, there will be a lot of foam, and the aroma will become more and more intense. When the coffee slow avoid drip filter to completion, a cup of hand brewed coffee is also brewed.
