Everyone who buys coffee beans knows very well that Taobao has many blue mountain coffee beans, boutique coffee beans and beautifully packaged gift box coffee beans and so on. Beginners are often deceived by a large number of orders on Taobao. They think that drinking freshly ground coffee is the so-called "good coffee". In fact, these coffee beans are so-called low-quality coffee beans, the main features: 1. Baking time is too long (deep baking) 2. There are too many rotten beans. Uneven size (uneven heating) 4. The planting technique is too poor, 5. Not fresh and so on; these beans are basically undrinkable when they are bought back, and some moldy beans are basically undrinkable if they are baked deeper.

Don't be greedy for petty gains, you'd better buy the amount you can drink within a month from the date of coffee roasting.

Because the freshness of coffee beans starts when they are roasted. Freshly roasted coffee beans will begin to exhaust (mainly carbon dioxide) for about a week, and when the gas is completely discharged (about two-three weeks), the coffee beans will no longer be fresh!

Tips that can judge the freshness of coffee beans:

. Oil: shallow to medium-roasted coffee beans, the surface will be foggy, almost can not see oil; deep-baked beans, there will be small particles of oil on the surface, the deeper the baking degree, the more oil.

Aroma: freshly roasted coffee beans will have a strong aroma; on the other hand, stale coffee looks bright and smells rich in fuel consumption, which means you buy stale coffee beans.

Foam: fresh coffee beans have more or less unemitted gas, so when hot water is poured on ground coffee powder, there will be foam on the surface, and coffee beans will produce bubbles and oils (crema) as if they are breathing.

Buying coffee beans with a clearly marked date is a smart choice.

Generally speaking, food products will look at the shelf life and taste period. Coffee beans belong to the food category. Some large coffee factories use central roasting to mass-produce coffee beans. The preservation period is usually between 12 and 18 months. But the preservation period and freshness are two different things. Coffee beans actually depend on the taste period. The fresher the coffee beans are, the better the coffee is!

Don't buy coffee of unknown origin or unclear label.

Many coffee merchants in the market have no choice but to buy low-quality and cheap raw beans for roasting because of price competition, so they do not dare to clearly mark their coffee identity cards. However, the eco-green coffee has a clear and complete identity card, which makes you feel at ease when you buy and drink.

Choose and buy bags with "one-way exhaust valve"

Roasted coffee beans are easy to oxidize, especially high temperature and moisture will speed up the oxidation and shorten the best taste period. it is recommended to choose bags with opaque light or one-way exhaust valve.

Drinking coffee is very subjective, to find good coffee, the most important thing is to know your preferences.

If you are not sure what kind of coffee you like, the editor suggests that you can first try black coffee without milk or sugar, cultivate your preference for coffee, and practice tasting the aroma and taste of coffee beans from different producing areas. Gradually, you will become addicted to drinking black coffee and find your own coffee flavor ​!
