"filter paper", "filter cup" and "filter cloth" hold their own corners when making coffee. Nowadays, the filter paper that is most widely used and controversial is "filter paper". Everyone must have heard or read some statements on the news, such as "is there any carcinogen in the filter paper?" , "is there any fluorescent agent in the filter paper?" "will the use of filter paper affect the flavor of coffee?" Today we will answer these questions once and for all and tell you what you should pay attention to when buying filter paper.

Select filter paper

There are many manufacturers of filter paper, such as CHEMEX, KONO, TIAMO ⋯, but you should know about the filter cup before choosing filter paper, because the filter paper is closely matched with it, and the shape and design of the filter cup will have an impact on the flavor of our brewed coffee, so you should consider the filter cup before deciding which brand of filter paper to buy, and there are the following reference points when choosing:

1. Modeling

The simplest reason is that you will not buy filter paper that does not match the shape, such as cone and ladder, so that your filter paper can not be put into the filter cup. For example, you use a V60 filter cup and buy a cake cup filter paper. What's the point of that?

two。 Size correspondence

The length and width of the filter paper should correspond to the filter cup of "several people". For example, a filter cup of 4 people, you can't use a filter paper of 2 Murray and 2 people.

3. Permeability of water

Different lines on filter paper, the filter function will be different, lines will affect the speed of water flow, paper thickness and grain pores are factors to be considered when buying, I personally suggest to choose the faster the flow rate, the better, because it can avoid the problem of excessive extraction.

What is the shape of the filter paper?

1. Wavy filter paper

The wavy filter paper is like a cupcake, and many people like it. The design of the wave is to let the coffee flow out of the filter cup directly after brewing, so the filter paper is three-dimensional in shape to prevent the filter paper clothing from sticking to the cup body. So it is very suitable for filter paper of all shapes.

two。 Tapered filter paper

The "V60" filter cup mentioned earlier is suitable for conical filter paper, because of the groove design of V60, it can increase the number of coffee powder disturbance and tumbling in the filter cup, and the tapered filter paper can form a tilt angle of 60 °with the filter cup. Coffee flows out along this groove design, which can do flood and fast flushing, but it will not let the coffee powder soak in the filter cup for too long. This is why "V60" can make the flavor very wide, but also very meticulous at the same time.

3. Circular filter paper

Love pressure is another way to extract coffee, which is a bit like the syringe principle of injection. of course, this technology needs corresponding filter paper to avoid drinking coffee powder.

There is a lot of controversy about filter paper. What is the problem?

People will mind. They are usually worried about whether there are chemical components in the filter paper, such as "wet strength agent" and "fluorescent agent". In fact, the problem of "fluorescent agent" can be easily solved. usually, if you choose filter paper close to "wood color" or "brown", you don't need to worry about bleaching and fluorescent agent. at present, there are also relevant units doing inspection, so there is no need to panic excessively.

In addition, the "wet strength agent" has been made a fuss by the media on the filter bag (or hanging-ear coffee) before, but after the inspection by SGS and the Food and Drug Administration of the Ministry of Health and Fuzhou, it has actually passed the test, and everyone can feel at ease to use it!

In fact, you can: constantly pour the filter paper on the filter cup with hot water to make it all wet, and water it repeatedly for 4 times (you can water it 10 times if you are handsome), which can remove the smell of the pulp. by the way, warm the pot and the warm filter cup, if there are any water-soluble chemicals, they will be washed away along with the hot water.

Finally, let's talk about the advantages and disadvantages of filter paper.

Advantages:

Filter paper is the most commonly used coffee filter material in the market. for coffee people who use filter paper, it brings us obvious "bright acid value" of coffee and can bring out distinct flavors. this is the common experience of every hand barista after use. what kind of fruit aroma should be drunk, the change after hot and cold, it can be said to be very obvious after using filter paper.

Disadvantages:

To say the disadvantage, probably there will be less oil in the coffee, the light roasting will taste mellow, or the smoothness does not seem to be as much as the metal filter, while the filter paper will relatively filter out some of the coffee flavor (such as bitterness, personal belief that the deep-baked taste weakens a little, other flavors, etc.), and then there is the problem of environmental protection, which is more or less a waste of paper. And when cooking, the pulp smell of the filter paper must be washed away with hot water first.
