The Importance of Coffee Bean Color Identification

The key to judging whether coffee beans are pure black is color identification. The color of coffee beans can reflect their roasting degree and quality, so for coffee lovers, it is very important to know how to correctly judge the color of coffee beans.

Light roast and dark roast

First, we need to understand the two different degrees of processing: light roasting and dark roasting. Light roasting usually makes the coffee beans appear lighter brown or yellowish brown. This treatment method can retain the original flavor and make the acidity more obvious. Dark roasting makes the coffee beans very black and produces a bitter and fragrant taste.

Observe the appearance

When we pick up a fresh coffee bean that has not been opened or exposed to the air for too long during the grinding process, we should first pay attention to whether it has a uniform color overall. Pure black coffee beans should be uniformly black overall, without any impurities or spots.

Smell it

Next, we can put the coffee beans close to our nose and smell them gently. Freshly roasted pure black coffee beans should have a strong and clear coffee aroma. If you can smell a distinct burnt smell or other odors, these may be caused by over-roasting or poor quality.

Touch surface

In addition, you can get more information about the color of coffee beans by touching their surface. High-quality pure black coffee beans usually have a smooth and shiny appearance and feel heavy. On the contrary, low-quality or poorly processed coffee beans may appear rough, dry and easily broken.

Use contrast method

The last method is to use the comparison method to determine whether the coffee beans are pure black. We can compare some coffee beans of known colors with the coffee beans to be judged. If the coffee beans to be judged are lighter in color or have obvious differences, then they may not be pure black.

Summarize

By observing the appearance, smelling, touching the surface and using the comparison method, we can relatively accurately determine whether the coffee beans are pure black. Correctly identifying the color of coffee beans will help you choose coffee that suits your taste and preferences, and can improve quality and enjoyment.
