"Ah! It's too hard to inject water around! The current is so difficult to control. There is no coffee rookie can be easily used, easy to operate filter cup recommended! After reading this message, the barista in front of the street immediately moved out the coffee brewing apparatus-Smart Cup, which integrates immersion extraction and filter extraction.

How should I use this "rookie coffee artifact"? In front of this issue, let's talk about how to use a smart cup to filter out a cup of coffee that won't turn over.

What is the Smart Cup?

The full name of the Smart Cup is "Clever Coffee Dripper". There are many filter cups with on-off valves on the market that are sold under the name "Smart Cup" by merchants, but in principle, only those sold by the Mr.Clever brand can be called "Smart Cup".

What's so special about the Smart Cup?

The bottom of the smart cup is divided into two layers, the outer layer is the support function, and the inner layer is designed with a pressing on-off valve. As long as it is not placed on the container, the valve is in a closed state in which the coffee powder can be soaked. After soaking, as long as the filter cup is placed on the container, the middle of the chassis will be pressed, prompting the piston valve to open and the coffee liquid to flow into the container.

How to use a smart cup to make filtered coffee?

Grinding degree

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.

In Qianjie, it is recommended that the degree of grinding of shallow roasted coffee beans in smart cup filtration should be medium and fine (the pass rate of standard sieve No. 20 is 75% ~ 80%). The degree of grinding of medium and deep roasted coffee beans is medium and coarse (the standard sieve No. 20 has passed 65% and 70%).

Water temperature

If the water temperature is too high, the coffee flavor will accelerate the release rate, and it is prone to excessive extraction. If the water temperature is too low, the coffee flavor release rate slows down, and it is easy to cause insufficient extraction. In Qianjie, 90 ℃-91 ℃ is recommended for shallow roasted coffee beans and 88 ℃-89 ℃ for medium and deep roasted coffee beans.

Powder-water ratio

Qianjie took the interval of SCA gold cup extraction (extraction rate: 18% Mel 22%, concentration: 1.15% Mel 1.45%) as the reference standard, using different powder-water ratio and filter cup for brewing experiments, and found that the extraction rate of coffee brewed at 1:15 was about 17.79% Mel 18.73%. Although the gold cup is only on the edge of reaching the standard, through sensory tests, it is found that the flavor is very suitable for the cooking of most coffee beans.

Next, the front street uses Costa Rican Stonehenge blueberry coffee beans for filtration 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%)

① folds the filter paper into the smart cup and puts the smart cup on the container. When the filter paper is wet with hot water, the appliance can be preheated at the same time.

② moves the smart cup to the electronic scale (the valve closes automatically) and pours the ground coffee into the center of the filter cup. In the first stage, inject 30g of hot water, press the timer and steam for 30 seconds; after stifling, pour hot water to 225g, then soak for 1 minute.

After soaking, move the smart cup to the container and open the valve to filter out the coffee liquid in the filter cup. The whole process takes about 15 seconds, and the total extraction time of coffee is 2 minutes 39 percent 05 ".

This Boulder Manor blueberry coffee beans have blueberry fudge, citrus acidity, rose aromas, ripe fruit fermented aromas, obvious sweetness and smooth taste.
