Moisture is the amount of water vapor or actual moisture in the substance. Fresh coffee grounds are low in moisture and, consequently, they do not degrade or spoil in the same way as other foods. Ground coffee can deteriorate when exposed to extreme moisture or light. When the coffee grounds are damp they may lose their flavor and develop mold. They can also lose their freshness and aroma.

Oxidation

When coffee beans are fully ripe, they undergo an degassing process, which releases carbon dioxide. You can tell if a bean bag is old or new by the smell.

This is also true for old ground, which may turn dull and flavorless if stored for too long.

Most coffee bags contain nitrogen (an inert, odourless gas that is safe for food items) to prevent loss of flavour. However, if you open the container or bag, the nitrogen is replaced with oxygen and moisture which will rob the grounds of their flavour (3).
