For optimal storage, Cherry PLUS should be kept in the freezer or refrigerator. Once opened, the product must be used within 12 weeks. In accordance with the high quality standards of the Cellavent freshness concept, our Montmorency sour cherry concentrate is stored at 7 degrees in order to protect its valuable ingredients as best as possible. However, the product can be stored outside the refrigerator for several weeks and months without any problems. This only has a minor impact on the quality. It only loses its valuable ingredients when stored outside the refrigerator for more than a year.
