How to evaluate coffee beans

Testing coffee beans is an important step in determining their quality and taste. Here is a common testing method, which includes observing the appearance, smelling the aroma, and tasting the taste.

First, observing the appearance of the coffee beans can provide some clues about their quality. Good coffee beans are usually shiny and uniform in color. If there are spots of grease on the surface, it may indicate over-roasting or improper storage. In addition, checking whether the beans are neat and uniform in size is also an important step.

Next, smelling is one of the key steps in evaluating the quality and flavor characteristics of coffee beans. Put the ground coffee into the cup, cover the mouth of the cup with your palm to stir, then quickly remove your hand and take a deep breath. This allows the aroma to fully release and better capture the characteristics of floral, fruity, chocolate or nuts contained in it.

Finally, there are several aspects to pay attention to during the tasting process: First, how is the balance between bitterness and sourness? The acidity of coffee beans affects its taste, and high-acidity coffee usually has a bright and refreshing taste. Second, how is the body feeling? Good coffee should have a rich and full-bodied taste, but also maintain a balance. Third, how is the aftertaste? After tasting, is the aftertaste left in the mouth pleasant? These factors can help evaluate the quality of coffee beans.
