Almond flour expiration: unmasking the myths and truths

Almond flour is a popular gluten-free alternative to wheat flour, made from finely ground almonds. It is packed with nutrients and has a slightly nutty flavor. However, like any other food item, almond flour has a shelf life, and it’s important to know how to store it properly to prevent spoilage.

• Grinding Method: Finely ground almond flour has a shorter shelf life than coarsely ground flour.

In general, unopened almond flour stored in an airtight container at room temperature will last for about 6 months. Once opened, it should be stored in the refrigerator and used within **3 months**.
