In the United States and many other countries, coffee is the most popular beverage (1).
Coffee and coffee-based drinks come in a wide variety of flavours and intensities. Coffee is high in antioxidants, which may help to promote health in addition to delivering a boost in energy (2Trusted Source).
If you consume or prepare coffee, you might be wondering how long it will last once you buy it. Regrettably, there is a scarcity of scientific study and food safety recommendations on how to store coffee properly. There is a need for more research into coffee storage and safety.
This post uses evidence-based information, advice from coffee company websites, and my own recommendations to provide storage tips for various varieties of coffee.

Recommendations for extending the shelf life of coffee
Whole coffee beans and even ground coffee can last a long time if stored properly. Because coffee is dry, it is unlikely that the varieties you buy for at-home usage may develop mould or other types of spoilage caused by moisture.
However, the shelf life of coffee varies depending on how it is prepared.
Coffee that hasn’t been brewed lasts longer than coffee that has been brewed. It also makes a difference where you keep coffee: on the counter, in the pantry, in the fridge, or in the freezer.
Coffee’s freshness and flavour can diminish if it isn’t kept in an airtight container. Cold temperatures in the fridge or freezer can affect the taste of dry coffee, but they can also preserve coffee for longer periods.
