Wet environment will make coffee beans sticky and affect their quality. It is recommended to store coffee beans in a sealed container to avoid the entry of humid air.

How to buy coffee beans:
Choose fresh coffee beans. When buying, pay attention to whether the color of the beans is consistent with the size of the particles. Good coffee beans are bright and shiny in appearance, and have a strong aroma without mixed odor. No matter what kind of coffee beans, freshness is an important factor affecting the quality. When purchasing, grab one or two coffee beans and chew them in your mouth. It is the top grade to be crisp and sound (indicating that the coffee is not wet) and fragrant on your teeth and cheeks, but it is best to pinch them by hand to feel whether they are solid or not, instead of buying crispy coffee.
If the coffee bean has lost its fragrance or smells stale, it means that the coffee bean is no longer fresh and is not suitable for purchase. Freshly fried coffee beans are not suitable for immediate drinking, and should be stored for a week to completely release the gas in the beans.
