Original | Three-minute Hand Brewed Coffee Extraction Method
1.
Boil purified water and prepare 20 grams of coffee beans while waiting for the water to boil, grind the coffee beans into granulated sugar for later use
2.
Ground coffee powder
3.
Fold the filter paper into the filter paper cup
4.
Rinse the filter paper and filter cup with hot water
5.
Pour the ground coffee powder into the filter paper
6.
Inject 50ml of boiled water at 93°C for 25-35 seconds. At this time, the coffee powder expands upward and bubbles are discharged. Its function is to release the carbon dioxide gas in the coffee, so that the coffee particles after exhausting uniformly absorb water, preparing for the subsequent uniform extraction.
7.
Continue to inject water into the core stage of brewing and extraction. This post uses the academic brewing method. It is not only easy to operate, but also has a relatively stable quality of extracted coffee, which is suitable for most filter cups and novices. This method is to inject water from the center of the coffee powder to the outside, then steam it, wait until it collapses and start to inject water slowly from the inside to the outside again. However, this technique has higher requirements for hand-punching. It requires a delicate, vertical, stable and uniform water flow in the hand-punching pot, so that a good cup of coffee can be brewed.
8.
About 2'10'' when the extraction volume reaches 240ml, stop water injection. The water flow should be kept stable during the water injection process. The water flow should be injected into the center area of the coffee powder at 90°. The water flow should not be too large or too small. At this time, the coffee powder is fully soaked, and the oil and some soluble aromatic substances are continuously released. When the ideal extraction is achieved Stop water injection when measuring.
9.
Drink directly after warming the cup or season it according to personal taste
Tips:
The extraction parameters in this post are derived from the recommendations of the Biluo Manor 303 coffee beans. Other coffee beans with flavor and roasting degree need to be adjusted as appropriate.
