Granola is a popular breakfast or snack option, and making it at home allows for customization and control over ingredients. However, like any food product, homemade granola has a limited shelf life and can go bad if not stored properly. In this article, we will explore the factors that affect the shelf life of homemade granola, how to store it to maintain freshness, and signs that indicate it has gone bad.
