What is the typical shelf life of coffee beans?
The shelf life of coffee beans depends on various factors, including the type of coffee, storage conditions, and roast level. Generally, coffee beans can last for several months when stored properly. Green coffee beans, which have not been roasted, can last for up to a year or more when stored in a cool, dry place. On the other hand, roasted coffee beans are more sensitive to light, heat, and moisture, and their shelf life is typically shorter, ranging from a few weeks to a few months.
To maximize the shelf life of coffee beans, it is essential to store them in an airtight container, away from direct sunlight and heat sources. The container should be kept in a cool, dry place, such as a pantry or cupboard. It is also important to note that coffee beans can absorb odors and flavors from their surroundings, so it is best to store them in a separate container to preserve their flavor and aroma.
