Coffee beans are the heart of every great cup of coffee, and their freshness plays a crucial role in determining the flavor and aroma of the brew. One common question that coffee enthusiasts often ask is how long coffee beans can stay in the hopper without losing their flavor and aroma. In this article, we will delve into the world of coffee beans and explore the factors that affect their freshness, as well as provide guidance on how to store them properly.
Understanding Coffee Bean Freshness
Coffee beans are a delicate product that can be affected by various factors, including light, heat, moisture, and oxygen. These factors can cause the beans to lose their flavor and aroma, resulting in a stale or bitter taste. The freshness of coffee beans is determined by the amount of time they have been exposed to these factors.
