Coffee brewing utensils: a detailed introduction to the evaluation of Stumptown coffee filter paper and filter screen

We are die-hard fans of hand-brewed coffee, and we are also keen on experiments. Therefore, we decided to join hands with the coffee teaching team to have a discussion on coffee filter paper to see if the choice of coffee filter paper would affect the result of coffee extraction. Here is a spoiler: it will really affect!

First of all, with regard to this experiment, one of our main purposes is to find out how filter paper affects the flavor of coffee. For the purpose of this experiment, we know that we need to exclude brewing methods and do experiments on filter paper alone.

In our first experiment, we filtered the water into the filter paper to observe the taste of the filter paper. Then pour the water into the filter paper and filter it again to see how the infiltrated filter paper tastes and is extracted with coffee during brewing.

Barista's small step: be sure to infiltrate your filter paper before making coffee! In this way, you can first filter out the smell and dust of the filter paper itself, and warm the filter pot.

The second experiment we conducted was to taste coffee brewed from different filter papers. So we brew coffee with filter paper in the same way and taste the difference in taste.

Chemex Filter

The Chemex filter paper itself is the driest and the most unchanged. The coffee extracted with Chemex has a low consistency, can bring out the aroma of flowers, and the taste is a little dry.

Melitta Oxygen Bleached

This bleached filter paper has a little residual taste when it is infiltrated. The overall consistency of the extracted coffee is thick and has no significant paper flavor.

Melitta unbleache Natural

This unbleached filter paper has a significant woody sweetness in both the primary and secondary infiltration. The extracted coffee has the aroma of filter paper and a very marked dry taste.

Hario V60

This filter paper smells like grass when it is first soaked, but it tastes dry when it is soaked twice. The extracted coffee has a bright and refreshing fruity flavor.

Sock Cloth Filter

This filter bag has the strongest smell, so let us tell you: it doesn't smell good. The extracted coffee has a marked aftertaste like a wet wool coat; some say this one reminds him of a second-hand store in Eugene Oregon.

What are our suggestions?

Choose something like Melitta Oxygen Bleached, Chemex or Hario V60! If you insist on using natural filter paper that advertises Natural, do a good job of infiltrating. Lose the damn thing in the filter bag!

"findings other than the experimental results:

We are surprised that the Hario V60 filter paper is so different-this filter paper is made of high-quality paper in Japan, which is lighter and more textured. The coffee extracted is full of floral aroma and brightness. Compared with Melitta coffee, it has a refreshing taste and more sour citrus flavor than other filter paper coffee.

Noil filter paper vs metal screen

Able Kone

Able Kone is actually a filter rather than a screen, which is basically a stainless steel cone filter with many small holes.

Although the shape of this filter is designed according to the size of the Chemex filter pot, you can brew coffee on any container that can support the filter. There is a great difference in flavor between the coffee brewed with Chemex filter paper and that brewed with Able Kone.

Chemex filter paper is the heaviest filter paper, so it can brew very dry and clear coffee, while Able Knoe brews coffee that is thicker, with fine powder (that is, tiny coffee particles), greasy and precipitate. The taste and texture of the coffee brewed with Able Knoe is similar to that brewed by the French filter press.

Able Disk

Able has also designed a stainless steel filter for AeroPress, which they call a Disk. This filter disc comes in two sizes: standard and ultra-fine, with different sizes of meshes and different useful life.

The coffee brewed by the standard filter has a thicker consistency and slightly more powder, and the more attractive thing is that this filter can be used for several years, and its durability is three times that of a very fine filter with the same thickness. The coffee brewed by the very fine filter plate is relatively clear and has a very rare powder. The very fine filter plate should be used with care.

Now you can see a big difference between a filter paper and a metal filter: compared with a metal filter, filter paper filters out most of the powder and grease, so there are fewer subtle flavor changes in the brewed coffee. If you like the crisp and clear taste, please choose the filter paper; if you like the thicker taste, or if you want to find a way of brewing without using the filter paper, try the filter plate.
