Honey stored in sealed containers can remain stable for decades and even centuries! However, honey is susceptible to physical and chemical changes during storage; it tends to darken and lose its aroma and flavor or crystallize. These are temperature-dependent processes, making the shelf life of honey difficult to define. For practical purposes, a shelf life of two years is often stated. Properly processed, packaged and stored honey retains its quality for a long time. If in doubt, throw it out, and purchase a new jar of honey!
