Each one can dramatically affect the flavour and quality of your coffee if not properly managed. Unlike milk or meat, coffee doesn’t become harmful to consume, but it does lose its punch.

While it won’t be as vibrant as fresh coffee, you may still get a decent cup if the beans aren’t too far gone.According to the National Coffee Association (NCA), coffee is hygroscopic—it absorbs ambient moisture from the air.
