How to preserve coffee beans? How can coffee beans last longer?
The main factors affecting the storage of coffee beans are temperature, humidity, oxygen and light. The higher the temperature, the higher the humidity, the higher the oxygen content, and the stronger the light, the faster the coffee beans will crack, causing the coffee flavor to decrease or disappear. Better preservation of coffee beans requires solving these problems.
Raw beans emit a lot of carbon dioxide after baking, so they are suitable for one-way exhaust valves lined with aluminum foil, which can block light and air. The one-way vent valve is used to vent excess carbon dioxide so that the bag does not burst without opening, but this packaging is not suitable for long-term storage of cooked beans. When you get coffee beans, if you have already passed the cultivation period (about 2-5 days after roasting), if you have not opened the packaging of beans, consider sealing the individual vent valve with transparent glue to reduce the loss of coffee flavor, or choose a sealed jar to store away from light so as to better retain the coffee aroma and extend the taste period of coffee.
