Coffee beans are the seeds of the coffee plant that are roasted and ground to make the aromatic and delicious beverage loved by many. But how long do coffee beans last before they go bad? The answer is not as straightforward as one might think. Several factors can affect the longevity of coffee beans, and it's essential to understand them to ensure the best quality cup of coffee.
The first factor that affects the lifespan of coffee beans is the roasting date. According to the Specialty Coffee Association (SCA), coffee beans are considered fresh for up to four weeks after roasting. The next critical factor is storage method. Whole beans tend to last longer than ground beans due to their reduced surface area. Additionally, the packaging also plays a role in preserving the freshness of coffee beans.
In general, whole coffee beans can last for up to six months in a cool, dry place. However, ground beans have a shorter lifespan of two weeks. To ensure the quality of your coffee beans, it's essential to know the signs of spoilage and the best ways to store them.

To tell if coffee beans are still good, you can rely on your senses. If they smell rancid or have a stale odor, it's a sign that they have gone bad. Similarly, if the beans look discolored or have a slimy texture, it's time to toss them out. Additionally, a change in taste can also indicate that the beans have gone stale.
To properly store coffee beans, it's best to keep them in an airtight container in a cool, dark place. This will help prevent exposure to air, light, and moisture, which can cause the beans to spoil. It's also recommended to only grind the amount of beans you need for a single cup, as ground coffee has a shorter lifespan.
If coffee beans have gone bad, consuming them may not pose any significant health risks. However, they may not taste good, and drinking expired coffee may result in an upset stomach. To extend the longevity of your coffee beans, make sure to store them properly and pay attention to their freshness.
