Deep-roasted coffee (Dark Roasting Coffee) refers to French or Italian roasted coffee after the second explosion in the baking stage. This kind of coffee is to enjoy the strong bitterness, sweetness and lasting aftertaste, so it is more suitable for strong extraction, such as light extraction, it is difficult to enjoy its strong texture.

The bitterness of coffee cannot be removed or reduced, but what kind of bitterness it belongs to is also important.
