Wilbur Packing

Wilbur Packing Company is a vertically integrated grower, packer, and processor of California prunes and walnuts, operating out of the Sacramento Valley since 1992. The company is an extension of Wilbur Ranch, a family farming operation with roots dating back to 1869, making it one of the most historically established agricultural enterprises in California. Five generations of the Wilbur family have cultivated over 3,000 acres of prunes and walnuts in the Yuba and Feather River bottoms — widely recognized as the world's premier growing region for these crops, owing to its fertile Columbia loam soil and temperate climate.

As a fully vertically integrated operation, Wilbur controls every stage of the supply chain, from orchard management and harvesting through packing, processing, and delivery to retail and supermarket customers. This farm-to-shelf model allows the company to maintain rigorous oversight of product quality, consistency, and food safety at every step.

Wilbur's premium prune offerings include a broad range of product types and sizes to serve diverse retail, foodservice, and ingredient buyer needs. Product types include Natural Condition, Whole Processed, Elliott and Fadei Pitted varieties, available in both Conventional and Certified Organic formats, as well as a Preservative Free option delivered through the proprietary "Wilbur Process." Prune sizing spans from Small through Extra Large, with count-based sizing from 20/30 through 100 count and smaller, providing flexibility for both retail pack and bulk ingredient applications. The company also offers Prune Puree and Diced Prunes as ingredient formats for food manufacturers and CPG brands.

The company exclusively sources 100% California-grown prunes and walnuts, differentiating itself from competitors that blend or obscure the origin of their fruit. California prunes are subject to a stringent quality assurance process that other origins do not replicate, and Wilbur positions this as a meaningful guarantee of quality and safety for its buyers.

Wilbur Packing Company's Quality Assurance programs incorporate advanced processing technology, systematic procedures, and continuous personnel training to ensure product consistency and safety across all SKUs. The company's integrated approach — combining deep agronomic expertise with modern food processing capabilities — positions it as a trusted, long-term supplier to grocery retailers, ingredient buyers, and private-label customers seeking premium California-origin tree fruit and nut products.
