What is the shelf life of almond flour?
The shelf life of almond flour depends on various factors, including storage conditions, packaging, and handling. Generally, unopened almond flour can last for 6-12 months when stored in a cool, dry place, away from direct sunlight and moisture. However, once opened, it’s best to use it within 3-6 months for optimal flavor and texture.
Proper storage is crucial to extend the shelf life of almond flour.
