How can I flush out the coffee grease? How to use flannel to make good coffee?
Coffee oil is essentially an insoluble substance in coffee beans wrapped in carbon dioxide, which can enhance the experience of coffee, such as making the taste richer, mellow, and prolonging the duration of the aftertaste.
In individual coffee, fat is also very common, but the difference is more or less. A friend is about to ask: why is there no grease in hand coffee? That's a good question! This is because the mainstream filtering tool used in hand-brewing coffee today is filter paper, which can not only filter tiny particles, but also isolate grease. So, if you want to try to bring some grease to your hand-brewed coffee, you can get a cup of hand-brewed coffee with grease as long as you replace it with a less filterable device.
Before the advent of filter paper, there was an appliance that had always been the number one player in filtering coffee grounds and was widely used. It can make the coffee surface appear obvious grease, and it is the protagonist we are going to use today-flannel filter cloth.
Flannel is a kind of special fabric, which shows a different touch on the inside and outside. There are cotton noodles on one side and velvet on the other. Cotton noodles can obviously feel the roughness brought by the grain, while the velvet surface feels smooth and delicate. Its biggest feature is that it can easily drop oil and other insoluble substances into the coffee through the filter cloth, which is an important factor to improve the mellow taste.
Because it is a filter made of different fabrics, but there is no distinction between the pros and cons, some friends will worry about "which side to use to hold the coffee powder". Both sides can be used for brewing and will not have any different effect on the coffee. Usually use more cotton noodles (the rougher side) as the inner bag, because it does not absorb too many coffee particles compared to the velvet surface, so it is easier to clean. If the suede surface is chosen as the inner bag, the small coffee powder can be easily absorbed on it, adding a lot of difficulty to the cleaning work after brewing.
Flannel "bracket" flannel filter cloth does not have a filter cup for support and diversion because it is not needed. It has a stainless steel ring with a handle. The stainless steel ring is connected to the filter cloth for support, so we can either put it on the sharing pot or brew it by hand.
Before cooking, we should first put the flannel filter cloth in boiling water and cook it for five minutes, so that it can be fully sterilized, and let the water be thoroughly integrated into the fiber to maintain the steady state of cooking.
Coffee beans: 20g deep-baked gold Manning powder / water ratio: 1:15 Grinding degree: the screening rate of No. 20 sieve is 70%, our shop uses EK43, the grinding scale is 11. Water temperature: 88 °C cooking method: flannel can choose two different cooking methods, this time using a hand-held filter cloth, combined with water injection.
It should be noted that the gap of flannel filter cloth is much larger than that of filter paper, so its launching speed is faster than that of filter paper. The attached cup supports the body without a filter cup, and its whole body can allow the coffee liquid to pass through, so the higher the water level, the faster the speed of launching. Then our hand-held cooking will use a larger amount of powder, first use a small flow of water to wet stew the coffee powder, and then inject water in a small circle in the center, in order not to let the water flow away from around.
After brewing, we can see that the coffee brewed with flannel has obvious coffee oil, while the surface of the regular hand-brewed coffee is very clean and clear. ).
Tasting time: two cups of coffee with different filtering tools have the same flavor, nuts, spices and chocolate. The difference is that coffee brewed with flannel is more mellow and smoother than coffee brewed with filter paper. But it can not reach the cleanliness of the filter paper, generally speaking, each has its own advantages.
Preservation method of flannel filter cloth
When we finish cooking, the first thing to do is to clean and store the filter cloth, because it is a filter cloth that can be used many times. But many people have a misunderstanding of storage, such as thinking that it can be washed and dried like normal utensils, but such wetting and drying will damage the fiber structure of flannel.
The right thing to do is to wash the flannel, place it in a sealed container filled with clean water, and then store it in a low temperature environment. This can not only ensure that the fiber structure of flannel is not damaged, but also prevent mold, but the disadvantage is more troublesome, need to change water from time to time, and boiling water is still needed when used again.
