The basic knowledge of fine coffee explains the method of brewing coffee machine in detail.

< 1 > filter drop method (Paper Drip)

1. First put the prepared filter into the drip, and then put the ground coffee powder (about 2 tablespoons per person, about 12 grams).

two。 Pour 95 ℃ of boiled water gently from the center and let the coffee powder permeate and spread through the boiling water. At this time, the coffee powder begins to expand and slowly sink, and wait 25 seconds before preparing to inject the second boiled water.

3. After the second injection of boiling water, the coffee powder starts to swell again and the coffee begins to drip down the bottom. Pay attention to the proper amount of water injected, too much coffee is thin and light, and too little bitter taste is strong (2 tablespoons per person, about 12 grams of powder boiled water is 120cc). When the top drip coffee completely flows into the drip pot below, the top drip pot can be removed and the coffee can be poured out.

Note: it is best to use a professional fine-mouthed coffee pot, ordinary kettle water is too large, generally this kind of fine-mouthed pot is about 280-500 I sell is 280.

Siphon boiling method (Siphon)

At present, this is the favorite style of most Japanese coffee specialties in Taiwan, commonly known as "sesame." because it feels so beautiful, it seems that the laboratory of chemistry once detonated the coffee bar in Taiwan, especially in many small shops. The principle is that the glass bottle is filled with alcohol to make it in a vacuum, and then the coffee is extracted by the principle of steaming force.

1. First boil the boiling water, pour it into the glass bottle at the bottom, and then add it again with alcohol.

two。 Then put the ground medium coffee powder into the top glass bottle (about 12 grams per person, boiling water about 120cc, and so on). After the water in the lower bottle begins to boil, insert the top glass bottle and fix it. (note that it is too early to insert the coffee to extract it perfectly.)

3. Completely lift the boiled water at the bottom into the upper glass bottle and then dissolve it completely with a tablespoon of coffee powder. After about a minute, the alcohol is extinguished, and the coffee liquid will flow through the cloth and back into the lower glass bottle. Remove the funnel above and pour out the coffee in the lower glass bottle.
