In 1908, a German housewife Melitta Bentz liked freshly brewed coffee, but she was a perfectionist suitor and hated the coffee grounds left between her teeth. One day, on a whim, she punched a hole in the bottom of the copper bowl, took out a piece of blotting paper from her son's schoolbag and put it into hot water, and immediately the mellow coffee dripped into the pot through the blotting paper. In this way, she invented a method of filtering dregs and retaining the aroma of mellow coffee. Before this invention, people used cloth bags to filter coffee grounds. However, the cloth filter bag is troublesome to clean and unhygienic after being used many times, and the coffee grounds left in the gap in the cloth bag are also easy to destroy the original mellow taste of coffee. From then on, a small piece of filter paper opened the concept of coffee filtration, and today it leads the trend of boutique coffee for a century.
