The freshness of coffee beans will directly affect the taste of a cup of coffee. Proper storage is an important factor affecting the freshness of coffee beans. How to store roasted coffee beans? Roasted coffee beans need to pay attention to humidity, temperature and oxidation. Oxidation will accelerate the flavor dissipation of roasted coffee beans.
So how long can opened coffee beans be stored?
The tasting period of coffee beans is 4-30 days after the coffee beans are roasted. Coffee beans that have expired do not mean that you can no longer drink them, but the flavor of the coffee will dissipate even if the beans are properly stored. Therefore, the flavor of coffee beans after 30 days may be insufficient or boring. Regardless of the flavor and aroma, the shelf life of roasted coffee beans is 365 days.
The taste period of ground coffee powder is shorter. If it is not stored well, it may lose its flavor within a week, so it should be used as soon as possible.
How can you preserve coffee beans as long as possible? Let’s first learn about the “killer” of coffee bean freshness
The “Killer” of Coffee Bean Freshness①
Light Source & High Temperature: Light source refers to sunlight. The heat of sunlight accelerates the volatilization of the aromatic substances (aroma) of the coffee beans. The inner layer of the coffee bean packaging sold by FrontStreet Coffee uses aluminum foil. The aluminum foil can reflect light, but it does not achieve true heat insulation, so the place where the coffee beans are stored should be away from heat sources.
The “killer” of coffee bean freshness ②
Humidity: Humidity refers to the moisture in the air. If the originally dry coffee beans are kept in a humid environment for a long time, even if they are protected by a sealed container, they will not be able to escape the intrusion of moisture when they are opened. Damp coffee beans are prone to deterioration and produce moldy and other odors, which will directly affect the taste of coffee, so a dry environment can better maintain the freshness of coffee beans.
The “Killer” of Coffee Bean Freshness③
Oxygen: When you see this, you may say: "Oxygen is everywhere, it is impossible to avoid oxygen~" Don't worry, the point here is not to prevent the contact between coffee beans and oxygen, but to minimize the contact time between oxygen and coffee beans. After we take out the coffee beans from the package, the coffee beans still in the package/container should be sealed as soon as possible to slow down the oxidation rate of the coffee beans.
