Coffee filter cup is an instrument for extracting and filtering coffee. Its main function is to hold the filter paper, so that the filter paper can effectively separate coffee grounds and coffee liquid, which is equivalent to a "support". The effects of different filter cups have their own characteristics. Because the distribution of coffee powder in different shapes of filter cups is different, the launching speed and the contact time between powder and water are different. What is the difference between cooking the same bean with different filter cups? This time we use hollowed-out filter cup and V60 to carry on the comparative experiment.

| 01 | filter cup introduction |

The flow rate of V60 is faster, which makes the exhaust effect of the filter cup more fluent, improve the extraction rate, and the curved ribs increase the way of water flow, which can greatly increase the contact area of coffee grounds with air and water, so as to avoid excessive water flow and insufficient extraction.

The skeleton of the hollowed-out filter cup is distributed in a network, the filter paper and air are fully released, the extraction is not easy to block, the water flow is smooth, and the water will flow down from around when brewing coffee, so the coffee brewed out will be relatively light. It is suitable for coffee with clear and balanced taste.

Both kinds of filter cups use the same cooking method, steaming at the same time and water, and using the same amount of water to complete the cooking. Try your best to achieve the consistency of the experiment.

02 | Cooking experiment

Take the red cherry of Yejiaxuefei as an example

V60 hand flushing parameters

Powder / water ratio: 1:15

Degree of grinding: BG4Z (medium and fine grinding)

Water temperature: 90 ℃

Brewing and cooking techniques:

Steam in 30g water for 30s

110g water injection section

It ends when water injection reaches 225g.

Finish the water injection at 1: 41 ", and wait for the water to be filtered at 1: 56".

Flavor: tropical fruits, spices, fermented wine, outstanding aroma.

Palate: rich layers and high mellow thickness.

Hollowed-out filter cup hand data

Powder / water ratio: 1:15

Degree of grinding: BG4Z

Water temperature: 90 ℃

Brewing and cooking techniques:

Steam for 30s with 33g water

110g water injection section

It ends when water injection reaches 226g.

1: 40 "finish the water injection, and when the water is filtered, it is 2: 07".

Flavor: berries, fermented wine.

Palate: the taste is balanced and clean, but the palate is slightly thin.

03 | conclusion

The flavor level of V60 cooking is outstanding, the taste is clear and transparent, and the alcohol thickness is high. The filter cup has a high bonding degree with the filter paper, but the flow rate is faster than that of the hollowed-out filter cup, because the design of the spiral ribs prolongs the extraction time of coffee liquid and coffee powder, and the design of the convex groove will produce a torsion, thus accelerating the extraction speed of coffee powder.

The fit between the hollowed-out filter cup and the filter paper is poor, and the filter paper is easy to fall in the process of cooking. The flow path of the hollowed-out filter cup is shorter than that of V60, and the flow rate is faster when there is more water, and when it flows to the back, the velocity will slowly decrease, the coffee liquid will flow out from all sides of the filter cup, and the extraction time of water and coffee powder will also be shortened. it's easier to cause insufficient extraction.
