Factors That Affect the Shelf Life of Ground Coffee
The shelf life of ground coffee is affected by several factors, including the roast level, grind size, and storage conditions.
- Roast level: Dark roast coffee has a longer shelf life than light roast. That is because the roasting process removes moisture from the beans. Not having moisture present slows down the oxidation process.

- Storage conditions: Proper storage is the key to keeping ground coffee fresh for as long as possible. Ground coffee should be stored in an airtight container, away from light and heat.
