It is best to buy the amount that can be finished within one 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:

1. 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.

two。 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.

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

Second, 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 coffee manufacturers 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 look at the taste period, the fresher the coffee beans, the better the coffee!

Third, do not 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.
