How To Tell If Coffee Beans Are Stale

Roasted beans usually last between two and six months.

Even if coffee is old, there is no such thing as 'expired coffee’. They'll taste stale and lacking in flavor, but they are not harmful to your wellbeing. 

However, there are a few things you can do to ensure that your coffee beans remain healthy and tasty for an extended period of time.

Both beans and ground coffee have the potential to go rancid. The longer beans and grounds remain, the greater the likelihood that they will spoil. It occurs even more quickly in warmer conditions

Maintain a cool environment for coffee beans instead of room temperature.

This is the most effective method of ensuring the safety of your coffee beans. Prolonged storage at room temperature accelerates the process of beans spoiling, the growth of the mold that produces OTA, a naturally occurring foodborne mycotoxin found in a wide variety of agricultural commodities worldwide, from cereal grains to dried fruits to wine and coffee. 

Place your whole beans in the freezer or, at the very least, the refrigerator. The cold will prolong the life of your coffee and preserve some of its flavors as it ages.

If you start with the best coffee possible, the chances of mold and OTA contamination are very low and you reduce the risk of bacterial contamination and mishandling.

Additionally, if you pay attention, you can determine when the coffee has gone bad. Fresh coffee has an intoxicating aroma. When coffee becomes stale, it loses its aroma. If it does not smell unpleasant, it is still safe to drink.
