Storage Information

To help ensure freshness, we recommend our products to be refrigerated after opening. Refrigerated storage of tree nuts helps to prevent the development of off flavors or rancidity. The ideal storage conditions are 45-55ºF in tightly sealed containers at 55-65% relative humidity. Please refer to best before markings on our packaging for shelf-life information.
