The packaging principle of coffee beans

For the convenience of consumers, coffee manufacturers have formed a set of established packaging identification in practice: red packaged coffee, which is generally thick in taste, can quickly wake up drinkers from last night's good dream; black packaged coffee, belonging to high-quality small fruit coffee; gold symbolizes wealth, indicating that it is the best in coffee. If someone can't help drinking coffee at night, please choose the blue package, which must be "caffeine-free" coffee. In addition, coffee with colorful packaging often has a unique taste. People who like to be curious can give it a try.
