Superbrewed Food

Superbrewed Food (formerly White Dog Labs) is an alternative protein company based in New Castle, Delaware, that has developed the world's first FDA-GRAS-affirmed postbiotic cultured protein ingredient (SB1) using anaerobic fermentation — the same biological process behind beer, yogurt, and kimchi. SB1 delivers over 85% protein content with a PDCAAS score of 0.91, along with vitamins, minerals, and fatty acids, and is allergen-free and non-GMO, making it suitable for food and beverage product development across meat-free and dairy-free applications. The company's B2B customers include major food manufacturers such as Bel Group and Döhler, which has begun commercial production of SB1 at its own facility.
