Hand-brewed coffee, the taste of the coffee brewed in this way is always so clean, and the aroma of the coffee is emitted at the moment when hot water flows from the curved spout into the coffee powder.
The perfectly curved retro palace pot, the long aroma in the air, the barista who stood straight and carefully drew circles with running water, always felt that this way of brewing was particularly elegant! However, many people think that hand-brewed coffee was invented by the Japanese, probably because many of the hand-brewed coffee utensils are Japanese brands. But in fact, it was definitely not invented by the Japanese. 100% of Europe originated, and we can only say that the Japanese have carried it forward on the basis of the original. When it comes to hand-made coffee, be sure to talk about Melitta Bentz in Germany. In 1908, this great housewife had been worrying about not being able to flush out a clean cup of coffee. How could she filter out the coffee grounds left in the coffee? Finally, on a whim, she tore off her son's notebook and put it into an iron can with a hole underneath. The initial filter paper and filter cup appeared in her kitchen. She immediately applied for a patent for filter paper and filter cup, which has been popular ever since. Hand coffee is quickly replayed for convenience. Put the filter paper into the filter cup, pour it into the coffee powder, then inject the hot water in a circle in the shape of "coffee". When a sufficient proportion of coffee liquid is extracted, stop injecting water, and then pick up the filter paper and throw it away, very convenient. The brewed coffee has a clean taste and pleasant aroma.
