how long is coffee good
Carbs go stale, lipids go rancid, volatile organic compounds evaporate, and other components change with exposure to oxygen (oxidation) or water. Even small changes can have a significant impact on the taste of your coffee. How long your coffee will last depends on its form, as well as where and how itâs stored. If taste is your concern, your best bet is to store coffee in an airtight container somewhere cool, dry, and dark. Stored this way, ground coffee can be used for a few months past its expiration date, whole bean for up to nine months, and instant coffee for up to twenty years.
