The shelf life of specialty grade coffee depends on various factors such as the type of bean, roast level, and storage conditions. In general, whole bean specialty coffee can last for up to 2-3 weeks after roasting, while ground coffee has a shorter shelf life of 1-2 weeks. However, some specialty coffees can last up to a month or longer if stored properly.

To extend the shelf life of specialty coffee, it should be stored in an airtight container away from heat, moisture, and light. Ideally, the container should be opaque and stored in a cool, dry place, such as a pantry or cabinet. It's best to avoid storing coffee in the refrigerator or freezer, as the moisture and odors can affect the flavor of the coffee.

It's important to note that while coffee can still be consumed after its shelf life, the flavor and quality may not be as good as when it was fresh. To ensure the best taste and aroma, it's recommended to purchase coffee in smaller quantities and consume it within the recommended time frame.
