Introduction to coffee equipment - filter

1. Where does hand filter paper come from?

Understanding filter paper First of all, we need to know that filter paper is mainly used for hand-brewed coffee. We should thank a German housewife, Bentz Melitta, for the popular coffee brewing method. She invented the coffee brewing method more than 100 years ago, which changed the history of coffee drinking in Germany and the world.

Benz Melita was born in Dresden in 1873. As a housewife, she loved Schälchen Heeßen (Saxon dialect, meaning a cup of coffee eine Tasse Kaffee) - freshly brewed coffee.

But she was a perfectionist and hated the coffee grounds left between her teeth. One day, she had an idea. She punched a hole in the bottom of the copper bowl, took out a piece of blotting paper from her son's schoolbag and placed it on top. Then she poured hot water into the bowl. The mellow coffee immediately dripped into the pot through the blotting paper. In this way, she invented a method of filtering the grounds and retaining the mellow coffee aroma (hand brewed coffee).

Before this invention, people used cloth bags to filter coffee grounds, but cloth filter bags are difficult to clean and unhygienic after repeated use. The coffee grounds remaining in the gaps of the cloth bags can easily destroy the original taste of the coffee.

Use a cloth to filter the coffee (like a stocking hanging at Christmas)

On June 20, 1908, Melitta registered her invention at the Royal Patent Office: a copper coffee filter with a water hole in the arched bottom, which was the world's first filter coffee cup; Melitta Benz used very little money to set up the "Melitta Company" in her own residence at the time, and used her own signature Melitta as the registered trademark for the product. This is the origin of hand-brewed coffee

In 1908, Ms. Melitta from Germany invented the use of "paper" as a filter medium. Since then, filter paper has become popular due to its convenience and flavor stability. The purpose of filter paper is to keep the coffee grounds in the filter and filter out the delicious coffee.

2. How many types of filter papers (filters) are currently on the market?

There are currently three types: filter paper, filter cloth, and metal filter.

1. Metal filter

The largest holes allow more substances to pass through, giving the richest coffee flavor, but at the same time, coffee brewed with a metal filter will have a lot of fine powder, which will interfere with and affect the taste. So many people think that such coffee is not clean enough to drink, but it can retain the best flavor integrity, and it can be used repeatedly after cleaning, which is a great tool for saving costs! !

2. Filter flannel

There are very few impurities that can pass through the filter cloth when brewing coffee. It can be said that there is no fine powder at all, and the taste is very clean. However, the weakness of the filter cloth is that it is not easy to maintain. The filter cloth must be boiled, wrung out, and refrigerated after use. Moreover, the filtering state and flow rate are different after using it ten times and a hundred times, which also increases the difficulty of brewing. But the price is not expensive, you can also buy one to play with.

3. Hand-wash filter paper

The advantage of coffee filter paper is that it is stable! The filtered coffee is very clean and easy to clean (just throw the filter paper directly into the trash can). Although the flavor performance is more pertinent, based on its other advantages, I still strongly recommend using filter paper to brew coffee.

The filter paper is currently available in two colors and two shapes (cone and cake cup)

1. The original wood filter paper will have a slight woody taste, which will affect the original flavor of the coffee in detail.

2. Bleached filter paper will have the smell of bleach. Bleached filter paper contains fluorescent agent.

Therefore, we recommend that you pass the filter paper through the coffee filter when brewing, which can effectively remove the odor. It is easier for the filter paper to fit the filter cup, and it is also easier to brew the extraction and flow rate. At the same time, different filter papers will also have a certain effect on the flow rate, but don't worry, practice more and control the flow rate. Remember that we are playing with coffee, not coffee playing with us.

The shapes of the filter paper and the filter must match each other;

The impact of three filters on flavor

Materials: filter paper, filter cloth, and metal filter

The metal filter has the largest holes, the flavor is complete, there are more fine powders, which affects the taste

The filter cloth has a more complete flavor and a clean taste, but it is difficult to maintain.

The flavor integrity of filter paper is average, but it is the most convenient and easy to clean.
