“Eat beer. Fight food waste” is the tagline for ReGrained, a San Francisco-based brand of snack bars made using spent grains harvested from craft breweries. Varieties include Honey Almond IPA and Chocolate Coffee Stout. The company plans to launch other products using the fiber- and protein-rich brewers’ grains, such as pretzels, Sarah Nathan, vice-president of business development, told Food Business News.
