Can roasted coffee beans be brewed directly?

Coffee is an indispensable drink for many people every morning, and coffee beans are an important raw material for making coffee.

These aromas will be fully released during the brewing process, making the coffee more fragrant and delicious.

Different brewing methods will affect the release of aroma and flavor substances in coffee beans, thus bringing different taste and flavor characteristics.
