Toast Brewing

Stuart is an author and campaigner on the environmental and social impacts of the food system, and the brewery was built around a single principle: divert bakery surplus from landfill by incorporating it into the brewing process. The concept took shape after Stuart encountered a bread-based beer at the Brussels Beer Project, where he found the brewing tradition of using surplus grain had ancient precedent. Toast Brewing operates on a contract model, partnering with established breweries to use spare capacity rather than running its own facility. The company donates 100% of its profits to charities working on food-system reform.

The AF offering is a 0.5% lager brewed in collaboration with the environmental charity Surfers Against Sewage. The partnership reflects Toast Brewing's pattern of aligning its products with environmental causes rather than treating them as standalone commercial releases. The brand entered the low-alcohol category in 2019 with its first sub-1% beer, and the AF lager is available through specialist alcohol-free retailers and mainstream online grocery channels.

Toast Brewing sits at the intersection of food-waste activism and craft brewing, a combination that distinguishes it from other AF lager brands on ingredient story alone. For sober-curious drinkers who want their purchase to carry environmental weight, it occupies a clearly defined position in the AF beer market.
