Coffee beans are a food that is easily affected by light, so the correct storage method is essential to maintain its freshness and taste. Coffee beans need to be stored away from light to prevent sunlight exposure and UV radiation. Here's how long coffee beans need to be stored away from light.
First, we need to understand the enemies of coffee beans - oxygen, humidity and temperature. These factors will cause coffee beans to deteriorate and lose their aroma and taste. The ultraviolet rays in the sun will accelerate this process. Therefore, it is crucial to store coffee beans in a cool, dry place that is not exposed to direct sunlight.
Secondly, under ideal conditions, whole coffee beans in unopened packages can remain in their best condition for up to 2-3 weeks. However, in real life, few people can use all the coffee beans they buy immediately after purchase. So if you have leftovers or purchase a large amount of freshly roasted good stuff, please be sure to store it properly.
Finally, after opening, be sure to transfer the remaining portion to an airtight container. This will prevent the intrusion of oxygen, humidity and temperature, and keep the coffee beans fresher for longer. If you have a lot of leftovers, you can divide it into small portions and take out only the required part each time to reduce the exposure time to the air.
