How to fold coffee filter paper? How to choose coffee filter paper? Do I need conical filter paper for V60 filter cups?

For most filter cups, whether the filter paper fits is a very important thing. Take V60, for example, if the filter paper is not fitted, then the guide bone on the filter cup can only play a role. Therefore, in order to give full play to the "efficacy" of the filter cup, we will try our best to fit the filter paper with the filter cup before brewing coffee.

Some time ago, Qianjie also shared the technique of "pressing the filter paper can improve the fit". I thought that the sharing of the fit could come to an end. As a result, a friend in the store responded in front of the street: "this technique can increase the fit of filter paper and filter cup, but it often does not fit." This made Qianjie very confused, so let him repeat the process on the spot. It turns out that the filter paper does not fit completely, which is more serious than the illustration below.

And because the problem was too obvious, it was found on the spot in Qianjie. That is: filter paper, no fold right!

Because the folding of the filter paper is very simple, Qianjie is often mentioned at once when sharing, and people usually don't care too much. But it is also because it is too simple that it is easy to ignore its importance. Under normal circumstances, a piece of wood pulp tapered filter paper fits well with the tapered filter cup after folding. Basically, it doesn't need to pour water to wet, it already fits with the filter cup. But if we find that when we put the filter paper into the filter cup, which side of the filter paper does not fit to the filter cup, it is very likely that it is not folded well, so this is the case (unless the filter cup is a type that cannot be industrially produced, such as ceramics). So today, Qianjie will demonstrate in detail: filter paper, how to fold correctly!

How to fold filter paper correctly? Below is a piece of bleached wood pulp cone filter paper. You can see that there is a seam on one side of the filter paper.

The first step we need to do when folding tapered filter paper is to fold it according to the suture line. So, let's fold it first.

After folding, you can press it smoothly with your fingers to consolidate the shape.

Then open the filter paper.

Then fold in half and fit the joint of the two sides.

After fitting, the key point comes! We press the suture line by pressing the crease line just now. This action is very important, as long as it is done, then there will be no channel behind the high probability, which can fit more perfectly. The pressing position is from beginning to end, first pulling and then smoothing.

At this point, the folding of the filter paper is basically completed. Next, we stick to the filter paper in the same way as in the original article. First of all, we open the filter paper into the filter cup.

It can be seen that the filter paper has basically fitted the filter cup perfectly before it is wet. But it is not enough, in order to ensure perfection, we need to use both fingers to press the position of the two crease lines of the filter paper. Press down to make sure the filter paper has completely hit the bottom.

When confirmed, we can pour water from the bottom up to wet the filter paper. Basically, the filter paper already fits perfectly with the filter cup.

However, this method can only be used for part of the filter paper, such as non-woven filter paper made of special materials need to be wet with hot water to make it fit. If we do not want to wet the filter paper, for example, when making iced coffee, after folding and putting the filter paper into the filter cup, press the filter paper in the same way, and then pour coffee powder into it. use the weight of the coffee powder to make the filter paper close the filter cup, so that the filter paper will not have a chance to warp in the brewing process.
