What are the characteristics of coffee made with flannel filter cloth? How to clean and maintain flannel filter cloth? What coffee beans are suitable for making flannel?

Before the 19th century, coffee was almost always made in the "brewed" form of Turkish coffee. The coffee beans are ground into fine powder and then boiled in a pot with water.

Since coffee is not ground in a very fine flour shape like that in Turkey, coffee in most areas will be filtered out with a filtering tool and then poured into a cup to enjoy. Otherwise, there will be too many coarse particles, resulting in a bad drinking experience. In the article "she invented the filter cup in pursuit of refinement," Qianjie shared that coffee filter paper was invented by Ms. Melita in the mid-19th century along with the filter cup. Therefore, before this, people's filtering tool could not be filter paper, but mainly used a kind of cloth bag made of special cloth, which was called "flannel filter cloth".

Flannel is transliterated from "Flannel", and the time and place of its use as a coffee filter can be traced back to Europe around the 17th and 18th centuries. The early flannel filter cloth was made of wool, but it was not until the emergence of cotton material that it became what it is now.

As said in front of the street, the previous function of flannel filter cloth in European countries (coffee) was only to filter out the coffee grounds in the finished coffee, not as an utensil for brewing coffee. It was later after it spread to Japan that the Japanese began to use flannel as the "filter cup" of drip coffee.

Then, because the coffee made by using flannel as a filter is different from the routine, and its use coincides with the craftsman spirit respected by the Japanese, even today, when coffee filter paper has become very popular, there are still many Japanese coffee shops using flannel filter cloth to make coffee.

What are the characteristics of coffee brewed with flannel filter cloth? Flannel filter cloth its biggest advantage is that the filtration performance is not as strong as filter paper, because it is made of cotton material, so the pore compared to filter paper will be much larger. This allows grease and some insoluble matter to be well retained in the coffee through the filter cloth.

There are certain aroma substances in the oil, which will be isolated from the coffee grounds when filter paper is used. Although this makes the coffee cleaner, it also lacks a small part of the aroma from the oil. The flannel filter cloth has larger pores, so it can release these oils, and the aroma of coffee can be more prominent with their addition. At the same time, insoluble matter refers to the fine powder of coffee, and the taste of coffee will be improved by the presence of the right amount of fine powder. To sum up, because of the larger pores, flannel filter cloth can produce delicious coffee with stronger aroma and more mellow taste, which is very suitable for the brewing of deep-roasted coffee.

The use of flannel filter cloth flannel filter cloth is divided into velvet surface and cotton surface. In the brewing of coffee, we can choose either side as the inner bag and the other side outward. Because the contact surfaces are different, there will be a slight difference in the taste of coffee between the two sides. But in general, people use flannel filter cloth on the inside and outside of cotton, because in this way the coffee powder will not stick to the cloth bag and it will be more convenient to clean.

Before the formal use of flannel filter cloth, people will wash the flannel filter cloth, and then soak in boiling water for a while, wring it out before it will be put into use. Because different from disposable filter paper, flannel filter cloth can be reused. After each use, it will go through a special cleaning procedure, disinfection, soaking, and then explain it in detail in Qianjie later. All in all, the "opening ceremony" is almost indispensable before using flannel filter cloth. Because of this, there are very few coffee shops using flannel in China.

And then it's about whether it's handheld or not! Traditional Japanese flannel cooking will hold flannel in hand in the process of cooking, because it was previously thought to focus people's attention, give people better control of the flow of hot water, and make the extraction more uniform. So basically, when we buy flannel filter cloth, we can see that it will be equipped with a wooden handle for hand-held use (you can also buy cloth alone). But the disadvantage of this practice is that it is more tired, so many people will directly set up the flannel filter cloth and use it directly as a filter cup. Both can be done, depending on what kind of experience you want to feel!

Then there are the parameters! Many people's flannel cooking will match the traditional Japanese cooking to "cook" deep-baked beans, with a large amount of powder and less liquid weight, that is, the so-called high concentration and low extraction. Because of the small amount of water used, it is necessary to extend the extraction time to improve the extraction rate. Then with a relatively thick, close to the sea salt-like grinding, to avoid the occurrence of over-extraction. Of course, we can also use conventional brewing methods to brew coffee, but it should be noted that due to the large pores of flannel, coffee liquid can ooze all over the body, so its flow rate is relatively fast (also affected by the thickness of the cloth). If we use the conventional way of cooking, we need to make some corrections to grinding, water temperature and water flow. Then there is not too much introduction in the front street here. You can try it on your own.

Cleaning of flannel when the coffee is brewed, in order to ensure that the flannel can be reused, we need to pour out the coffee grounds, then wash the filter cloth with clean water, and then boil and sterilize for up to five minutes. Remember, it is best not to use detergents such as detergent to clean, otherwise it is easy to leave the smell on the filter cloth. However, such a cleaning method is very difficult to wash off the coffee adsorbed on the filter cloth, so Qianjie will suggest that after the disinfection is completed, we use the cleaning powder of the coffee machine to soak the flannel filter cloth to remove coffee stains and store them.

The specific method is to remove the filter cloth from the handle, then put it into a sealable container, pour in water and cleaning powder, and then seal it into the refrigerator for cold storage. Wait until the next time we want to use it, then repeat the "opening ceremony"!
