Best Cob stores our corncobs indoors to reduce contamination.

We store all of our corncobs indoors to ensure protection from rain, snow, dirt, and environmental exposure. This ensures all of our corncobs are fresh and free from decomposition, rot, mold, mildew, sand, and contaminants, which degrade and impact the quality of other processed corncob products.

We implement continued quality testing to ensure consistency.

Best Cob continually tests our products throughout the production process to ensure consistency and quality. We implement an initial quality check once production begins, and draw samples throughout the production process. Sample testing includes bulk density, a visual inspection and a particle size screen test to guarantee consistent particle sizing and flow.

Best Cob has over 210,000 sq. ft. of production space, on a 70-acre campus. We grind over 34,000 tons of corncobs annually, and modernized production operations in 2015 with a new digital production control system for remote production monitoring and control, hammer mills, bag houses, and sifters. In 2017, an expanded quality lab was added, including new testing equipment and materials.
