These in-shell pecans are prized for their long-lasting freshness, rich buttery flavor, and high nutritional value. The shells protect the nutmeat from oxidation and can be stored in a cool, dark, dry place for up to 4 weeks. For longer shelf life, store in-shell pecans in the refrigerator for 6 months, or in the freezer (sealed in airtight containers or bags) for up to 2 years, as the shells protect them from drying out or absorbing odors.
