What brand of coffee filter paper is good for bleaching and how to choose the advantages and disadvantages of log filter paper?

Do you think Qianjie is going to have a meal when you see the cover? no! The thing is, Qianjie has been using Japanese Kono brand bleached filter paper, the price is about 0.30 yuan a piece. Recently, in front of the street, I saw that the unit price of a Spanish filter paper was close to 3 yuan, and I immediately raised my interest. What is the difference between the filter paper with a price difference of 10 times?

In the past, the knowledge of popular science filter paper in Qianjie will focus on whether the filter paper matches the filter cup and whether the log filter paper is better or bleached filter paper. And this issue will directly have a hard core, quality, what standard should be used to measure it. The filter paper that was thought to be more expensive than Jin Gui was Chemex filter paper, which is only 1 yuan per piece, while this 3 yuan filter paper has already formed a big gap in price. Let's take a look at the filter paper introduction given by the seller. Since it is so expensive, call it "high-priced filter paper".

From this, we can see that the filter paper has no smell of paper, organic materials, packaging efforts, only large filter paper specifications, can flush out a clean and bright flavor. But it's not worth 10 times the premium. Then let's compare the quality of the filter paper. First of all, we should compare the material structure of the filter paper and carefully observe the lines on the filter paper. We find that the grain of this high-priced filter paper is more delicate, while the Kono filter paper commonly used in Qianjie has a more obvious striped concave and convex texture. Kono will be softer in terms of softness and hardness.

Next, compare the cooking performance. When I read the introduction in front of the street, I found that the flow rate of this filter paper is faster.

Then let's make a horizontal comparison, because this filter paper is the size of 1-4 people, so the comparison is based on the specification of Kono filter paper 02. Two groups of filter paper are wet by water injection in the bonding state, this high-priced filter paper is very perfect in the bonding degree, and it is very strong and has a good shaping effect. Of course, the Kono filter paper also fits the filter cup very well, but it is not very strong, and some of the filter paper is affixed to the filter cup.

Yega Snow Prunus cherries are also used as beans for cooking (20g), and three-stage water injection is used in front street. The extraction time of using high-priced filter paper is 2 minutes and 18 seconds, and that of using Kono 02 filter paper is 2 minutes and 36 seconds. This also confirms that the flow rate advertised by high-priced filter paper is faster. Review the performance in the cooking process. Look at two pictures first.

The above image is a high-priced filter paper, from the water droplets between the ribs in the picture, we can see that the height of the whole powder layer does not reach the shortest ribs, but it is very close. The powder layer of the kono filter paper in the image below has reached the edge of the short ribs, and the water has been guided down. In this case, the extraction time of high-priced filter paper is faster, indicating that the high-priced filter paper is thinner and the flow rate is faster. Another phenomenon is that coffee liquid filtered by high-priced filter paper will have poor permeability, and there will be a layer of glowing grease floating on the surface, while kono filter paper has better permeability. This also shows that in terms of filtration performance, high-priced filter paper is slightly inferior. Of course, this is not a derogatory evaluation, compared to some flannel players like greasy coffee.

While tasting these two cups of coffee, as you can see, the coffee filtered by kono filter paper is cleaner and brighter. High-priced filter paper tastes better. This seems to be in conflict with what he claims to be bright and clean with immediate results. Maybe different cooking methods will show a different effect! Generally speaking, this filter paper is quite comfortable to use. However, the improvement in cooking flavor is not obvious, that is to say, if you spend 10 times the price, you can get only 1.5 times the experience.
