As a coffee connoisseur, you’re likely aware of the importance of using high-quality, fresh coffee beans to brew the perfect cup. But have you ever wondered how long whole coffee beans last? The answer to this question is crucial in determining the optimal time to consume your coffee beans and ensuring that they retain their flavor and aroma. In this article, we’ll delve into the world of whole coffee beans and explore their shelf life, factors that affect their longevity, and tips on how to store them to maximize their freshness.
Understanding the Shelf Life of Whole Coffee Beans
Whole coffee beans are known for their longer shelf life compared to ground coffee.
