Know Where Your Products Come From


Where do you source your wheat?

We source wheat from multiple farms across the nation for two reasons: access to different types of wheat needed for specific products, and to add an extra level of safeguards for our ingredient supply.

Where do you mill your wheat?

As the oldest continuously family-operated milling company in the United States, it’s no surprise that we mill our own grains. We have two flour mills where we mill our own flour: our original Pioneer Flour Mill facility in San Antonio, Texas, and our Morrison Milling facility in Denton, Texas, which we acquired in 2006.

How do you ensure traceability?

We follow industry best practices in traceability to ensure verifiable evidence in harvesting, processing, production, and distribution. All incoming ingredients are carefully screened and documented prior to entering our facilities. Our advanced screening system connects with our warehouses to ensure that only approved, traceable ingredients are allowed into our plants.

What are wheat specs?

Wheat Specifications are the units and standards of measuring wheat quality. The most common are Protein Content, Moisture Content, Bulk Density, Gluten Content, and Gluten Index. C. H. Guenther specifies a tight range of acceptable criteria for our grain. We have identified parameters for each of these measurements enabling us to mill high quality wheat into high caliber flour that goes into our superior products.

Our 40+ member R&D team combines a spirit of innovation with real-world know-how. With over 400 combined years of experience, C.H. Guenther & Son’s R&D staff is committed to delivering new product support to keep your operation onthe forefront.
