Coffee beans are a fundamental ingredient for brewing a delicious cup of coffee. Knowing how long they last can help you avoid drinking stale coffee. The shelf life of coffee beans depends on several factors that affect their quality. Factors such as the type of bean, roasting level, packaging, storage conditions, and initial freshness influence the duration of coffee beans’ lifespan.

When it comes to coffee beans’ shelf life, it’s crucial to pay attention to its freshness both before and after roasting. A freshly roasted bean typically lasts for two weeks before it starts losing its flavor and aroma. However, if stored appropriately in an airtight container and placed in a cool, dry place away from sunlight and moisture, it can last up to four weeks.

Additionally, the type of packaging plays a significant role in extending or shortening the lifespan of your coffee beans. It would be best to purchase whole bean coffee in opaque packaging that has a one-way valve as this allows carbon dioxide to escape while preventing air from entering.

One thing important to note is once you grind your coffee beans, you start the countdown on their shelf life as they have more surface area exposed; therefore oxidation occurs more rapidly compared to whole bean coffee.

Even coffee beans have an expiration date, but don’t worry, they won’t judge you for hoarding them like your ex’s old t-shirts.
