The piston pot method is called the pressurization method in France, the Metro method in the United States and the coffee pot method in Europe, which is a quite good method of coffee blending. Many people like to make coffee in this way because it preserves all the flavor of ground coffee beans, but it is difficult to do so in other ways, which will make the coffee taste like filter paper. The piston pot is said to have been invented in 1933 by an Italian named Kahliman who sold designs and patents to Switzerland in order to escape Italy during the war. The method of using a piston kettle is very simple. Preheat the pot first. Put in the roasted coffee powder, add hot water and stir, soak for a few minutes, push down the stainless steel piston with mesh, separate the coffee powder from the liquid, and finally pour the coffee juice from the piston pot.
