Toast Brewing Makes Beer from Bread—and a Business from the Story

Toast Brewing built a beer business using surplus bakery bread, connecting a distinctive product to a practical food-waste solution.

Toast Brewing began with a production question: could surplus bread be used to brew beer? Environmentalist Tristram Stuart, sustainability adviser Louisa Ziane and brewer Rob Wilson developed the idea into a business.

The team launched its first beers in 2016, using surplus loaves as part of the brewing process. Toast’s recipe replaces some malted barley with dried breadcrumbs, linking the product’s story directly to how it is made.

A purpose-led product still has to satisfy everyday customers. Taste, availability and price influence repeat purchases; the waste-reduction story can make the first purchase more memorable.

Toast’s experience shows how a specific supply-chain input can become a product identity. The broader lesson is to connect a sustainability claim to a practical operating choice and explain it clearly.
