Walnuts are commonly sold either as halves or as pieces. Product listings typically indicate the form with labels such as “Form: Halves” or “Form: Pieces.”
Package sizes vary widely. Net weights shown in listings range from small consumer sizes (for example, about 6 ounces) up to large bulk sizes (for example, about 160 ounces).
Some listings specify a country (for example, the United States), while others use a variable notice such as “Varies, Please See Label” for origin information.
Walnut halves are commonly listed for snacking and for use in baking and cooking—examples include adding crunch to salads, yogurt, oatmeal, granola, and other sweet or savory dishes.
Product details recommend storing walnuts in airtight containers. For organic shelled walnuts, listings often advise refrigeration (up to about six months) or freezing (up to about twelve months); descriptions also note that walnuts generally have a long shelf life if stored properly.
Red walnuts are described as having ruby-red or red skin and a bolder, buttery flavor. Listings note the kernels can be slightly oilier and reference the variety’s origin by natural grafting rather than genetic modification.
