Xylitol should be stored in the pantry away from heat. It is pretty like sugar and absorbs moisture if any does come in contact with it. If it is unopened and kept out of heat and humidity, the xylitol can be good for a long while after its expiration date.

Xylitol should not be stored in the fridge. The cold can cause the xylitol to turn, and the refrigerator can build moisture and condensation in the xylitol if not correctly stored.
