Hand-flushing filter cup is one of the most important factors that determine the presentation of hand-flushing flavor. But when we pick the player to flush the filter cup, where do we start? What are the points for attention?

This time we will from the material, flow rate, filter media and filter cup size, these four aspects of comprehensive analysis, let you choose the most suitable for your hand filter cup!

I. material

At present, the filter cups on the market are mainly made of ceramic, plastic, glass and metal. Different materials will affect the water temperature, while the extraction temperature and drinking temperature will make the coffee flavor different.

In terms of these four materials, ceramic is the best filter cup material for thermal insulation, but the premise is that the ceramic must completely warm the cup in order to have a perfect thermal insulation effect. If there is no warm cup, the specific heat and mass of the ceramic are larger. The filter cup itself will absorb the temperature of water, and the water temperature may be lower than that of other materials.

The hand filter cup made of metal and plastic is stronger and more resistant to falling, but the heat preservation effect is also poor.

Second, flow velocity

The flow rate is the length of time that the coffee stays in the filter cup, which is easy to be extracted for too long, resulting in a bitter taste; if the time is too short, the extraction will be insufficient, making the coffee taste weak. It is an important factor that must be considered when making hand-brewed coffee, which has a far-reaching impact on the taste of coffee.

Fan-shaped and cake-shaped filter cup, the bottom of the dripping filter caliber is smaller, the flow rate is slower, and the water volume is better controlled, while the conical filter cup has larger dripping diameter and faster flow rate.

Tapered filter cup, usually with large caliber and fast flow rate

In addition to the type of filter cup, the service degree of filter paper and filter cup will also affect the flow rate. if the filter paper is more affixed, hot water will flow out easily from the bottom of the filter cup, resulting in a decrease in flow rate. Therefore, there are lines on the inner edge of most filter cups, so that hot water can flow out of the filter cup smoothly. The grain depth of different materials is also different, usually the plastic grain is more obvious, the ceramic is more gentle.

In addition, the folded line of the fan-shaped filter paper is just in the drip filter hole, and the filter paper blocks the hole to make the fan-shaped filter cup flow more slowly. some manufacturers have introduced a first-line filter cup to make a straight-line raised rib at the bottom of the fan-shaped filter cup. the purpose is to make a gap between the filter paper and the filter cup. Some people put toothpicks on the bottom of the fan-shaped filter cup, which has the same effect.

III. Filter media

The most common filter media are filter paper, filter cloth and metal, each of which has its own advantages and disadvantages, but none of them is the most perfect method. It can only be chosen according to one's preference for coffee. Filter paper is easy to use, coffee taste clean, but easy to have filter paper flavor, and will filter out coffee oil, compared with filter cloth and metal, coffee alcohol thickness is insufficient.

Compared with filter paper, filter cloth can maintain a mellow and smooth taste, the biggest disadvantage is that cleaning is troublesome and maintenance is not easy. The hole of the metal filter cup is larger than that of filter paper and filter cloth, which retains the rich and complete taste of coffee, but there will also be fine powder left in the coffee liquid, affecting the taste, which is a good choice for those who do not reject fine coffee powder.

IV. Filter cup size

The size of the filter cup is usually divided by weight, which is divided into 1: 2 and 1: 4. However, the selection should be based on the actual amount of coffee needed and the concentration of coffee. For example, if you brew coffee with a high concentration in a 2-person filter cup, the filter cup space may be a little insufficient. The diameter of the mouth of the 4-person filter cup is large, and the mode of operation is relatively free, but when brewing coffee, the hand pot may hit the filter cup.

These are the four considerations for the selection of hand-flushing filter cups, but in fact, no matter which filter cup you use, you have to consider other factors when brewing, including coffee variety, grinding thickness, water temperature, brewing time, continuous water, and so on. To make a good cup of coffee, it's not as simple as buying a good filter cup!
