Factors contributing to coffee staling

For the prevention of oxidation, it is essential to use airtight, sealed bags or containers to minimize contact chances with air.
Moisture content
Moisture is one of the main catalysts in staling. High moisture can cause rancidity. As well, extreme dry conditions will also have a negative impact, such as when beans lose their natural oils and become stale quickly. So, that is why it is important to maintain the moisture level.
