Grain4Grain is a San Antonio-based food-tech startup focused on producing low-carb, high-protein flour from brewers spent grain, a significant byproduct of the brewing industry. The company has developed a patent-pending process that efficiently dries and mills this spent grain in under 20 minutes, a significant reduction from the conventional six-hour method. By upcycling this resource, Grain4Grain not only creates a nutritious ingredient but also promotes sustainability within the food supply chain. Since its launch 10 months ago, the company has upcycled 120,000 pounds of spent grain and introduced two consumer packaged goods in nearly 200 HEB stores. Additionally, Grain4Grain is actively pursuing contracts with various product makers, bakeries, and even a dog food manufacturer to expand its market reach and product offerings.
