Extraction mode is carried out by soaking.

In fact, water accounts for more than 98% of each drop of coffee. The American Fine Coffee Association used to quantify the concentration of total dissolved solids (TDS, total dissolved solids) measured by an optical refractometer. If less than 1% of a cup of coffee comes from coffee beans, our taste will be considered too light. On the contrary, if the content is more than 2%, it will generally feel too strong. The differences between nationality and taste are reflected in the concentration standards of different boutique associations. In the United States, it is between 1.2% and 1.4%, while northern Europeans have a heavier taste and prefer a concentration of between 1.3% and 1.5%.

Hand-brewing coffee seems simple, but in fact, there are many technical details to master and too much equipment to prepare. Different factors in the process of hand-brewing may cause different flavors. For a coffee beginner, after discovering his favorite taste, it is difficult to write down his formula. Even if all variables (temperature / powder / water ratio / time) are the same, the taste of the hand will not be the same next time.

The most important feature of the smart filter cup is the piston at the bottom of the filter cup. After hot water is injected into the filter cup, the water pressure closes the piston, prevents the hot water from flowing out, and allows the coffee powder to soak fully. After soaking, the filter cup is placed on the coffee cup or sharing pot, and the bottom is pressed to open the piston. Coffee flows into the cup.

After the traditional filter cup is injected with hot water, coffee flows out of the bottom, which has higher requirements for the speed of water injection, and it is also necessary to skillfully master a stable flow of water, otherwise it will easily become a lack of flavor. And smart filter cup, simple operation can fully show the meticulous flavor of coffee.
