How long does it take to soak and extract in the smart cup? What is the smart cup suitable for cooking with coffee beans? flavor and taste characteristics

Clever Coffee Dripper smart cup combines the advantages of French pressure pot and hand filter cup, which is simple, convenient and easy to use. Even if you are a beginner in coffee, you can easily get a cup of coffee that tastes good in just two minutes. If you are also worried about mastering a steady flow of water, and can not accept the "powder feeling" of French-pressed coffee, then the smart cup is a better choice.

There is a movable circular part in the middle of the smart cup, which is usually in a submersible state (there are four feet below for him to hang in the air), and the piston firmly blocks the current. When placed on a cup or sharing pot, the moving part is pushed up and the water can flow down. The design of the smart cup makes it have more immersion extraction function than the ordinary trickle filter cup, and the water and coffee powder can be kept in contact in the container until the concentration is enough. The soaking style is less affected by water injection, and it is easier for beginners to copy the basic flavor of coffee. The flavor substances will change the flavor and concentration of coffee with the water temperature, the ratio of powder to water, the thickness of grinding degree and the time of soaking.

Smart cup filter coffee is the same as brewing coffee with filter cup filter paper. Under the same water temperature, powder-water ratio and extraction time, the grinding degree of the same coffee bean is too coarse, and the coffee flavor is easy to be extracted insufficiently, resulting in insipid flavor and lack of layers. If the grinding is too fine, the coffee flavor is easy to be excessively extracted, that is, after the flavor substances are extracted, the coffee powder is still in contact with hot water and hot water, releasing unpleasant flavors such as wood, resulting in strong coffee flavor but mixed flavor. Since it is a "dual-use cup", the smart cup can not only act as an ordinary filter cup for direct filter extraction, but also use soaking to make coffee. Here in the front street, take the red cherry coffee beans in the store as an example to introduce how to use smart cups to soak and extract coffee.

Smart cup filter coffee is the same as brewing coffee with filter cup filter paper. Under the same water temperature, powder-water ratio and extraction time, the grinding degree of the same coffee bean is too coarse, and the coffee flavor is easy to be extracted insufficiently, resulting in insipid flavor and lack of layers. If the grinding is too fine, the coffee flavor is easy to be excessively extracted, that is, after the flavor substances are extracted, the coffee powder is still in contact with hot water and hot water, releasing unpleasant flavors such as wood, resulting in strong coffee flavor but mixed flavor. Qianjie recommends that the degree of grinding of shallow roasted coffee beans in smart cup filtration is fine sugar grinding (the pass rate of standard sieve No. 20 is 75% ~ 80%); the degree of grinding of medium and deep roasted coffee beans is medium grinding (65% and 70% of standard sieve 20).

The effect of water temperature and grinding degree in extraction is the same. The higher the water temperature is, the faster the release rate of flavor substances of coffee powder is, which is prone to excessive extraction. When the water temperature is too low, the release rate of coffee flavor slows down, and it is easy to lack of extraction. In Qianjie, 90 ℃-91 ℃ is recommended for shallow roasted coffee beans and 88 ℃-89 ℃ for medium and deep roasted coffee beans.

Since it is immersion extraction, the length of time directly determines the flavor and concentration of coffee. Qianjie has made a comparison of the soaking time of a smart cup before, with 2 points, 3 points, 4 points, 5 points, 6 points and 10 points respectively. By comparison, the flavor of 2-4 minutes is better, with the flavor of small tomato and pineapple dominating, in which the sweetness is more prominent as time goes on in this range. Combined with this experiment, we can see that the flavor of the smart cup will be better when soaking shallow roasted coffee for about 3-4 minutes. Next, the front street uses the Yega Xuefei sun-tanned cherry plan for brewing demonstration. Water temperature: 90 ℃, powder content: 15g, ratio of powder to water: 1:15, degree of grinding: medium and fine grinding (Chinese standard No. 20 sieve pass rate 75%), soaking time 4 minutes ① folded filter paper into the smart cup, put the smart cup on the container, wet the filter paper with hot water and preheat the appliance at the same time.

② moves the smart cup to the electronic scale (when the valve closes automatically), pours the ground coffee into the center of the filter cup, directly injects the 225ml water to make sure the coffee powder is all wet, then close the lid and wait for 4 minutes.

After soaking, move the smart cup to the container and open the valve to filter out the coffee liquid in the filter cup.
