Coffee Filters

Hario V60, Kalita, Chemex and Melitta, despite having their own design, these are some of the methods known as: percolation methods. Percolation means: passing (a liquid) through a medium to filter it or extract substances. This means that when we add water to ground coffee, the water must pass through the “coffee bed” extracting the maximum of its aroma and flavor. However, the methods that operate by percolation usually rely on a filter, which can be made of metal, paper or even cloth. Next, we'll look at the main differences between coffee filters.

_ Of metal

Due to the structure of its fabric, metallic filters are known for allowing the passage of coffee oils. The result is a full-bodied drink full of texture.

On the other hand, some insoluble particles are also capable of passing through its fabrics, polluting the drink and causing a rather unpleasant experience.

_ Of paper Paper filters, in turn, are capable of blocking all insoluble coffee particles, as well as most of its oils. The result is an extremely clean cup. However, it is necessary to emphasize the importance of scalding the filter before starting the coffee extraction. The use of high temperature water to scald the filter can reduce the presence of residues left over from the paper treatment (whatever it is, natural or white), as well as the presence of unpleasant cardboard flavors. *To learn more about this, be sure to visit The Importance of Pouring the Filter Before Making Coffee.

_ Of cloth Cloth filters can make excellent cups as their mesh structure is capable of blocking insoluble residues but not coffee oils, resulting in a clean but full-bodied cup. Nevertheless, these filters must be very well scalded before preparing the coffee, as well as sanitized after use and stored in appropriate places to avoid microbiological developments that could compromise the health of the tissue. Finally, it is noteworthy that the chosen grinding will also influence the result of the drink in our cup. So, take the test to find the best particle size for your filter and your taste.
