The differences between the two types of coffee are as follows:

1. Different working modes: At the beginning, only American coffee machines were able to provide fully automatic mode machines. If an espresso machine wants to obtain good coffee taste, it needs to strictly follow the many steps of manual coffee making and can only implement semi-automation.

2. Different working principles: Italian coffee machines usually use a boiler to generate hot water and pressurize the hot water to a certain pressure to brew coffee, so that there will be emulsified oil on the upper layer of the coffee. The working principle of the American coffee machine is to pour hot water on the coffee powder and then flow out, making the coffee taste lighter.

3. Different usage characteristics: American coffee machines only have fully automatic mode, which is more convenient and quick to use, and is more likely to be loved by people at home. The espresso coffee machine can make simple coffee as well as a variety of coffees, and can also meet the needs of home and business.
