Hand-brewed coffee uses coffee filter paper not only to separate coffee grounds from coffee liquid and improve the purity of coffee, but also because factors such as the material, thickness and porosity of the filter paper have an important impact on the extraction efficiency and coffee flavor. When choosing and using coffee filter paper, you need to fully consider these factors to get the best hand-brewed coffee experience.
The reason why hand-brewed coffee uses coffee filter paper is mainly based on its professional functions and characteristics in the coffee extraction process.
1. Basic functions of coffee filter paper
The main function of coffee filter paper is to effectively separate coffee grounds from brewed coffee liquid during the extraction process, so as to obtain a filtered coffee with a clean taste and no residue or sediment. This is an important part of hand-brewed coffee’s pursuit of high-quality taste.
2. The impact of coffee filter paper on coffee flavor
Improve the purity of coffee: Coffee filter paper can prevent coffee grounds and tiny particles from entering the coffee liquid, ensure the purity of coffee, and make the coffee flavor clearer and cleaner.
Affecting extraction efficiency: The thickness and porosity of coffee filter paper will affect the extraction efficiency of aromatic substances and oils during the extraction process. Filter papers made of different materials, such as bamboo fiber, Manila hemp, eucalyptus pulp, etc., have different fiber lengths and porosities, which have a significant impact on the extraction efficiency and coffee flavor.
Reducing the taste of cardboard: Unbleached filter paper may have a cardboard taste, which will affect the final flavor of the coffee. Therefore, wetting the filter paper with warm water before brewing can remove some of the cardboard taste and make the coffee purer.
III. Precautions for the use of coffee filter paper
Adapting the filter cup: When choosing a filter paper, make sure its size and shape match the filter cup. Different filter cup styles (such as conical and flat bottom) have an impact on the extraction process and water flow rate, so choosing the right filter paper is crucial.
Preheating the filter paper: Preheating the filter paper and filter cup with warm water before brewing can reduce the temperature difference with the hot water and improve the temperature stability during extraction, thereby ensuring the accuracy of the coffee flavor.
Control the water flow: When brewing, the extraction efficiency and flavor of the coffee can be further affected by controlling the water flow rate and injection method. Therefore, using the right filter paper and correct brewing technique is the key to obtaining high-quality hand-poured coffee.
