Italian Coffee with attractive knowledge of Coffee Culture

Italian coffee: Italian coffee is usually brewed at home using a mocha pot invented in Italy, which also uses the principle of vapor pressure to quench coffee (another Watt's apprentice). The mocha pot can make the pressurized vapor pass directly through the coffee powder, allowing the steam to pass through the cell wall of the coffee powder (or Hook's apprentice), quenching out the inner essence of the coffee, so the brewed coffee has a strong aroma and strong bitter taste, and a thin layer of coffee oil appears on the surface of the coffee, which is the source of the attractive aroma of Italian coffee.
