Filter method definition


Filter is a manual method of brewing coffee, which is brewed through filter paper with a ratio of 1:17.

For this method, we must choose a coarse grind of 1000 micrometers, because each blender will have a different grind level, in µm units to show accuracy and uniformity. The standard extraction temperature for the Filter phase is 92 degrees Celsius, this is the thermal framework for developing aroma bands. The time to complete the brewing phase will be within 180 seconds, and each pour will be 30 seconds apart.

A reasonable extraction percentage is 20 ± 0.5%, reflecting the coffee’s extraction level. If the total dissolved solids reach 1.25%, the extraction level is guaranteed with this extraction level you will be able to taste the coffee as delicately as a cup of tea. This method gives baristas the opportunity to try new recipes.

Brewing a filter for original coffee is the perfect way to experience all the concentrated flavors of high-quality coffee. It can be the clear, pure sweetness of Colombian coffee. Or the deep fruity flavors of Ethiopia according to the natural process.

Paper filter


Paper disposable coffee filters such as CAPEC are probably the most popular, as they are affordable and easily available. But even such a popular filter is separated into two categories: bleached and unbleached.

Bleached paper filters will be exposed to chlorine or oxygen. That chemical action causes them to turn from a natural tan to a bright white.

When it comes to bleached filters, those that use oxygen are a better choice, as oxygen has a less harmful environmental impact than chlorine. However, even oxygen bleached filters are not technically good for the environment. You may not know, these bleached filter papers themselves still contain enough chemicals to cause pollution when we throw them away without careful sorting.

+ In contrast, unbleached filters do not have the same bright white appearance as bleached filters, but instead are brown. Although they don’t look clean, they are much more environmentally friendly and natural. As the name suggests, paper filters do not undergo bleaching, and when it breaks down, they dissolve naturally into the ground which won’t be as harmful as bleach.

Bleaching or unbleached will not change the taste of your coffee. But perhaps you will wonder because it affects the living environment


Metal filter


Unlike a paper filter, the metal mesh construction will not absorb any flavored coffee oils. The more that exists, the stronger the cup of coffee will be and the stronger the aroma will be.

Metal mesh filters, usually stainless steel or aluminum, are devices celebrated for their environmental friendliness. They can last with you forever if properly maintained. This means that we won’t have to reluctantly “litter” just because of our cup of coffee.

However, most metal mesh filters are not good enough to filter everything out of your cup of coffee. Microbes (small coffee grounds) can still accumulate on the bottom of the cup. While a build-up of grounds isn’t a big deal, if you’re someone who is super focused on the finesse and smoothness of your coffee, it can also cause minor inconveniences. In addition, the taste of coffee beans after extraction with a metal filter also carries a little “metallic smell”, which is unpleasant and sometimes overpowers the aromatic coffee.


Fabric filter


Fabric filters are not as commonly used as paper and metal filters. They filter out all the beans, plus the small coffee grounds, while barely absorbing any of the flavored oils into the clear cup of coffee.

Most filter cloths are made from organic cotton. But linen and hemp are also popular choices for the wide selection of fabric coffee filters currently on the market.

These filters are not very popular in the market. Mainly because it is quite inconvenient to maintain. You have to wash them thoroughly every time you make coffee, and you certainly don’t want them to be damp after being cleaned, nor do you want them to dry out too much.

The cloth filter is also quite easy to preserve the taste of the coffee you have previously brewed. That shouldn’t be a big deal if you’re brewing the same coffee every day, but if you’re someone who likes to change up your coffee frequently, this can ruin your brewing process.
