The finishing and receiving of flannel filter cloth is very troublesome, and it takes a long time to filter, so most people stay away from it, but it has become one of its unique charm.

Flannel filter cloth can carefully and slowly extract the delicious ingredients of coffee beans. The coffee filtered has a round and deep taste, which is the greatest charm of flannel filter cloth. Therefore, when using it to filter coffee, please face every step carefully and remember to be a little emotional.

What is flannel?

Flannel (Flano,Flannel) is a loanword. It is a soft, suede (cotton) woolen fabric made of carded (cotton) wool yarn. It was founded in Wales, England in the 18th century. In China, it generally refers to the mixed-color carded (cotton) woolen fabric with embroidered style, one of which is covered with plump, fine and clean fluff, does not reveal the texture, feels soft and smooth, and has a slightly thinner body than Melden.

What is the difference between using flannel filter cloth and filter paper?

Because the pores of flannel are larger than filter paper, it can retain some of the oil esters of coffee, unlike filter paper, which usually filters out all oil esters, so the coffee made with flannel is thicker and smoother than filter paper.

In addition, in the process of brewing, because the fluff pores of the flange are thick and can be filtered at all positions below the water level, unlike the filter paper which can only be filtered through the gap between the filter paper and the filter cup, flannel filtration speed is slightly faster than the general filter cup filter paper combination (flannel flow velocity is different between front and back).

Background knowledge of flannel filter cloth hand-made coffee:

Flannel filter hand brewed coffee (Nel drip) tastes mellow, thick and incredibly sweet, reminiscent of sweet wine. It is not easy to brew good coffee in this way. Too fast water injection, too high water temperature, and immature techniques will degrade the flavor of coffee.

Some people say that making a good flannel filter requires the attention of a novelist, the dexterity of a surgeon, and the ability of a performer to improvise, which shows its delicacy and complexity. The more time you spend with coffee, the more you will be able to bring yourself a leisurely mood, and the coffee made from flannel filter cloth has a strong taste and a mellow finish for a long time. If you want to taste the change of beans, it is illegal blue velvet filter cloth.

Step 1

The brand new flannel filter cloth must be removed, soaked in boiling water for 5 minutes, and then placed on the metal ring.

If it is a used filter cloth, it should be boiled in boiling water for at least 3 minutes.

Step 2

Grind beans while soaking the filter cloth. Because of the special material of the flannel filter cup, the flannel filter cloth uses a little more coffee beans by hand than when using filter paper, and the taste of the filter will be better. Of course, the right amount of coffee powder should be loaded according to the size of the filter cloth. 2 cups (240c.c. Use 40 grams of beans. It is recommended to grind the coffee beans into a thickness between white sugar and fine sugar.

Step 3

Dry the filter cloth, twist it by hand, and then put the filter cloth in the middle of a clean dry towel to absorb dry.

Step 4

Rinse with hot water, preheat the filter cloth and drip filter, and then pour out the water.

Step 5

Pour the coffee powder loosely into the filter cloth without special compaction.

Step 6

Using a wooden mixing spoon or cream knife, gently flip the coffee powder from the bottom up, and finally pull the bottom of the bag to adjust the shape.

Step 7

Make a hole about a coin wide and a thumbtack deep at the top of the coffee powder. This is because the powder layer is deep, so it is convenient for hot water to spread in all directions and moist coffee powder evenly.

Step 8

After the hot water is set and cooled to about 80 degrees Celsius and 85 degrees Celsius, the water is injected from near the concave hole. It must be very slow at first, injecting 60 grams of water within 30 seconds. There is no need to soak all the coffee powder, capillarity will slowly spread the water. After the water injection is completed, wait for about 30 seconds.

Step 9

Start the second injection, this time faster than the first, with 140 grams of water in 60 seconds. At this time, the coffee will cause a large number of bubbles, which is a bit like the explosion of the universe in the movie. After the water injection is completed, wait 20 seconds, and the water level drops slightly.

Step 10

The last water injection, this time 120 grams of water in 30 seconds. The whole process takes 3 minutes to inject 320 grams of water. Because the filter cloth and coffee powder absorb about twice as much water as coffee powder, you can finally get about 240g of coffee, which is better than 1:6.

Using flannel filter bags to make coffee is time-consuming, so the temperature of the coffee is relatively low, and preheating the coffee cup can slightly increase the temperature of the coffee. But never reheat the coffee in any form.

Notes for flannel filter cup coffee:

1. The velvet surface can be tested either on the outside or inside, and the difference is the speed of filtering water. If you use the fluffy side to make the inside coffee grease and fine powder will stick to it. The flannel mesh will be slightly clogged, causing the water to filter more slowly, depending on the beans and the wishes of the individual.

2, do not pour water on the edge of the powder layer, in the water injection until the end can not wash to the filter cloth, to form a powder pit, otherwise cooking will be uneven.

3. Flannel filter cloth should be as close to the cup as possible, and the position of the spout should be as close to the surface of coffee powder as possible, so as to facilitate the adjustment of water output and water injection speed.

4. The filter cloth cannot be cleaned with detergent, but it can be reused about 50 times. When the coffee bean oil on the cloth cannot be washed off, it means a new one.

5. After using flannel filter cloth, it is best to soak in water. If it is summer, it is recommended to keep it in the refrigerator. When you need to use it, wring it out hard to remove moisture. If it is not used for a long time, it will be air-dried and then sealed, otherwise the moisture contained in the filter cloth will affect the flavor of the coffee, so we must pay more attention to it.
