When purchasing whole, unshelled nuts, look for clean shells without cracks. Whole, raw shelled nuts should appear relatively uniform in color and size. Nuts keep best in their shells. Because of their high fat content, nuts can turn rancid quickly. For best quality protection, store nuts in a cool, dry place in sealed plastic bags or in tightly closed containers.
Nuts keep well up to a month in the pantry.
For longer storage, it s best to refrigerate or freeze nuts. For more information, contact your local Colorado State University Cooperative Extension office . Go to top of this page.
