What Grain Millers Inc. does

Grain Millers, Inc. is a privately held, Minnesota-incorporated food production company founded in 1986, headquartered in Eden Prairie, MN, and operating across the US and Canada. The company manufactures and merchandises organic and conventional whole grain ingredients — primarily oats, but also barley, wheat (red and white), corn (yellow and white), rye, triticale, flax, soybeans, quinoa, and specialty seeds. It self-describes as the world's largest organic oat processor and produces approximately one-quarter of all oats in North America. Operations span ten facilities (manufacturing, warehousing, and a 300,000 sq ft storage site in Junction City, OR) including sites in St. Ansgar (IA), Eugene (OR), Marion (IN), St. Peter (MN), Newton (WI), Junction City (OR), and Canadian sites in Yorkton (SK), Rycroft (AB), and Delisle (SK). The company also operates a wholly-owned flax subsidiary, Enreco (Newton, WI), acquired in 2012.

Core technology centers on proprietary grain processing: a chemical-free mechanical process that yields intrinsic and intact oat fibers compliant with FDA dietary fiber regulations, a proprietary gluten-free process achieving 10 ppm versus the FDA's 20 ppm threshold (deployed across multiple facilities), and 30+ years of kilning expertise for shelf stability and traditional toasty flavor. The product portfolio includes milled grains in whole, cut, rolled, and flour forms; a fiber and functional flour line (oat fiber, oat hydrocolloid, micro-ground oat bran, colloidal and low-viscosity whole oat flour, and the trademarked CereSweet oat sweetener); supplied specialty products (soybeans, seeds, quinoa, amaranth, sugar cane alcohol); and feed byproducts (flax meal, oat mill run, hominy, custom feed blends). Services include on-site custom blending at Eugene and St. Ansgar, food-science formulation assistance, and full-service consumer co-packaging with private-label capability across canister, pouch, carton, and single-serve formats.

The business model is B2B enterprise ingredient supply combined with custom blending and co-manufacturing services. Revenue streams are ingredient sales, custom blending services, consumer co-packaging (including private label), and feed byproduct sales. Pricing is quote-based with a 10,000 lb minimum for direct purchases and a distributor network for smaller orders. Sales are organized by region (Midwest, West, Canada, International) with dedicated crop specialists and field representatives working directly with farmers and food processing customers. End customers include food manufacturers, cereal companies, bakeries, cookie and bar manufacturers, snack producers, and dairy-free alternative product manufacturers. Certifications stack includes USDA Organic / Oregon Tilth, Ecocert Canada, BRCGS, GFCO and Global Standard Gluten-Free, Non-GMO Project Verified, OU and OK Kosher, multiple Beth Din certifications, and Halal. The company is privately held with no parent, no public ticker, and no disclosed outside investors.
