Can out-of-date coffee make you sick?

No, out-of-date coffee won’t make you sick. Coffee does not go bad as in developing mold unless stored incorrectly. What generally happens is that coffee loses flavor as time passes and becomes stale. 

This happens because the flavorful compounds evaporate due to oxidation when the coffee is exposed to air/oxygen. Whether it’s canned or bagged ground coffee or whole roasted beans, they will degrade quickly once past their printed date.

An unopened package of ground coffee will last 2-3 years in the fridge. If opened, it will last 1-2 years only. An opened or unopened package of ground coffee will stay fresh for only 5 months in the fridge If stored correctly. 

Brewed coffee can be stored in the fridge for 3-4 days. Instant coffee, opened or unopened, will last up to 20 years past its best before the date in the fridge.

How to store ground coffee?

Ground coffee, due to an increased surface area, is quick to spoil if not stored properly. Ground coffee should always be stored in a dark and dry place. Use an opaque air-tight container or a vacuum-sealed package to keep the air and the moisture at bay. 

Opaque containers will reflect most of the light. It is better to use coffee vaults instead of going for regular containers. If you bought the coffee in bulk, separate some of the coffee into a separate and smaller container.

Separate the amount that you know will be consumed in the next 2 weeks. By doing so, you are ensuring that the coffee in bulk is not exposed to air and other contaminants on a daily basis.

Freezing coffee will extend its shelf-life to years. But the flavor won’t be the same. The brew extracted from frozen coffee will lack interesting and complex flavors.
