Experience Matters.

100+ Years of Grain Expertise.

Highland Milling stands on a foundation built with over 100 years of collective experience in cereal byproducts, ingredient sourcing, and agribusiness.

As part of the Cerco Group, Highland Milling benefits from the deep heritage of Cereal Byproducts Company, which began operations in 1917 and grew to become one of the most trusted suppliers of feed-grade and ingredient-grade cereal byproducts across North America. Drawing on this legacy, Highland delivers oat, barley, and rye products that meet rigorous standards of quality, safety, and consistency for customers in both the food and pet nutrition markets.

As a modern milling operation, Highland Milling combines cutting-edge facilities located in one of the country’s premier grain-growing regions with the Cerco Group’s century‑long experience in sourcing, logistics, and regulatory compliance. This unique blend of historical expertise from Cereal Byproducts and new‑generation milling capabilities means clients can trust Highland not just for premium grains, but also for supply chain reliability, product integrity, and responsive service, all under the Cerco Group's proven stewardship.
