Superbrewed Food Inc., a biotechnology research startup based in New Castle, Delaware, focuses on microbial fermentation to produce alternative protein ingredients. Its core offerings are postbiotic cultured proteins derived from fermentation, intended for inclusion in food products. The company, previously known as White Dog Labs, launched the SB1 ingredient in partnership with Döhler, signaling progress toward commercial-scale production of a postbiotic protein. 

The firm collaborates with major industry players to bring its ingredients to market, including Bel Brands USA and a partnership with Fonterra to develop nutrient-rich biomass protein. A manufacturing alliance with Döhler aimed to increase production capacity ahead of launching its first retail products. In 2026, the company announced expansion plans in the United States to repurpose a larger anaerobic fermentation facility and support longer-term growth.
