Does the coffee machine need filter paper?

Will the coffee espresso be better with a filter paper?

　　As an indispensable tool for making drinks in modern life, the working principle of the coffee machine has a subtle connection with the taste of coffee. Whether the coffee machine needs filter paper depends mainly on the type of coffee machine. Drip coffee machines usually need to use filter paper to filter coffee grounds to ensure the pure taste of coffee.

　　For Italian coffee machines that extract espresso, filter paper is generally not required. Its high-pressure water flow can directly extract the essence from the coffee powder to form a rich coffee liquid. At this time, if filter paper is forcibly added, it may affect the natural flavor and taste of the coffee.

　　As for whether filter paper can make coffee taste better, this is not absolute. The main function of filter paper is to filter impurities and improve the clarity of coffee. But for coffee lovers who pursue specific flavors and tastes, the use of filter paper may not be the best choice. Whether to use filter paper depends on personal taste and the type of coffee machine.
