In-Shell

 When sourcing in-shell walnuts, it is critical that you purchase from a supplier in a superior growing region since you cannot inspect the meat inside without destroying the walnut. Our reputation and high standards are why customers keep returning for our in-shell walnuts.

Processing

All walnuts are sized and graded according to USDA or EU specifications. To ensure our in-shell walnuts meet and exceed these specifications, we pass them through a rigorous grading process. It begins by sizing them, followed by a trip through two aspirators to remove shriveled and empty walnuts. The walnuts then pass over two electronic sorters that remove discolored and split shells. Lastly, an army of trained sorters removes the most minute imperfections.

In-shell walnuts are processed with two distinct finishes, Natural and Bleached. Natural walnuts pass through a brush scrubber to remove any loose hulls. Walnuts requiring a bright exterior appearance pass through a bleach solution.

Not all walnut varieties are available in each size classification. Availability of size depends on the variety, crop year and customer demand.
