How to tell the difference between good and bad coffee beans: Experts teach you how to identify good and bad

Coffee is one of the most popular drinks in the world, and choosing high-quality coffee beans is essential to making delicious coffee. However, for most people, it may not be easy to distinguish between good and bad coffee beans. In this article, we will introduce you to some expert ways to tell the difference between good and bad coffee beans.

First of all, observing the appearance of coffee beans is the first step to distinguish their quality. Good coffee beans are usually shiny and have a smooth surface. If you find beans with many flaws, cracks or uneven colors, they are likely to be inferior. In addition, you should also pay attention to whether the color is uniform when selecting. High-quality lightly roasted coffee will show a bright and uniform brown or dark brown color.

Secondly, smelling can also help us judge the difference between good and bad coffee. High-quality coffee has a strong and fragrant aroma, and can make people feel a variety of complex and pleasant taste characteristics. In contrast, low-quality or over-aged coffee beans usually emit a sour or moldy smell. Therefore, when buying coffee beans, you can first smell the aroma in the bag to help judge its quality.

Finally, grinding and brewing are also important steps in evaluating the quality of coffee. High-quality coffee beans should produce uniform and fine powder after grinding, without too many debris or particles. When brewed with these powders, good coffee should have a strong and balanced taste, and be able to show a variety of complex and pleasant taste characteristics. On the contrary, low-quality or stale coffee may produce problems such as bitterness, blandness, or even difficulty in swallowing.

In short, appearance, aroma, grinding and brewing process are key factors in distinguishing good and bad coffee beans. By observing whether the appearance is smooth and uniform, smelling whether the aroma is fragrant, and conducting appropriate testing and tasting, we can better select high-quality coffee beans to make delicious coffee.
