Many people's first reaction is that filter paper does indeed play a crucial role in filtering coffee grounds and fine powder. However, filter paper in coffee brewing not only filters out coffee grounds and fine powder, but also reduces the intake of harmful substances, such as cafestol and cafestol. This requires understanding the components of coffee after roasting.
We know that coffee has a complex and diverse composition, including caffeine, tannins, proteins, fiber, and minerals. Among these components, some are beneficial to the human body, while others may pose potential harm. For example, cafestol and cafestol in coffee oils can increase the concentration of triglycerides and cholesterol in the blood.
Using filter paper to brew coffee effectively removes most of these harmful components, helping to protect cardiovascular health. To reduce the intake of cafestol and cafestol, and thus better protect cardiovascular health, using filter paper to brew coffee is recommended. For coffee lovers who are accustomed to using Moka pots, French presses, or other brewing methods, simply adding a filtering step to their existing methods allows them to enjoy an even purer coffee.
