Spent Grain Flour Scales From Breweries Into Crisps and Puffs
Brewers and food groups are drying and milling spent grain into fibre-rich flour and building snack lines around it, aimed at shoppers who want fibre, protein and a circular economy story, and large brewers have set up ingredient arms. Brewers' Spent Grain Crisps and Puffs grow about 15.4% a year, and gross margins run 38% to 50%. The trend needs drying capacity, flavour masking and certification, and it rewards brands with brewery ties, while feedstock logistics limit scale. Buyers judge suppliers on consistency, documentation and delivery reliability. Makers with scale and clear plans hold the strongest positions.
