Does Ground Coffee Go Bad? How Long Is Fresh Ground Coffee Good For?

Storage is super essential to coffee!

Ground coffee can go wrong if it is not stored correctly. However, with the proper storage techniques, ground coffee can last several months. 

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.
  • Grind size: Finely ground coffee has a shorter shelf life than coarsely ground coffee. That is because the larger grind size allows less surface area for the coffee to come into contact with air. Which slows down the oxidation process.
