Hi all, last week I was quite busy, implementing an AI agent to automate a workflow.
Quick tip, if you are looking for a job in a high-impact company: Escape the City (I’m not an affiliate, it’s not sponsorship, nothing). I occasionally just share what I like.
I’d appreciate it if you could hit the comment button and answer this simple question: what newsletter format do you like the most? The current one or this one?

So, let’s talk beer 👇
The problem
~44% of bread in the UK supply chain is wasted before reaching consumers: surplus from bakeries, sandwich manufacturers, and supermarkets
Conventional craft brewing is grain-intensive: barley malt is one of the primary cost inputs
Surplus bread has no commercial buyer; it goes to landfill, animal feed, or anaerobic digestion
Barley farming is land, water, and energy intensive; scaling craft beer means scaling those inputs proportionally
The food system wastes the ingredient that brewing has to buy.
Toast Ale
Founded in 2016. Tristram Stuart. United Kingdom.
Tristram Stuart had spent two decades campaigning on food waste, including founding Feedback, a food system charity. He visited the Brussels Beer Project, which had been experimenting with bread-based brewing from ancient recipes. The model already worked. He brought it to the UK with a commercial structure: sell craft beer, give every pound of profit away.
What they do:
Brews craft beer using surplus fresh bread as a partial replacement for barley malt
Sources surplus from UK bakeries and sandwich manufacturers
Sells via ecommerce, UK retail, and a global network of collaborating breweries
Donates 100% of profits to Feedback; commits to a minimum of 1% of revenue in unprofitable years
Holds investors to an “Equity for Good” model: capital gains must be reinvested in social impact businesses, not taken as personal profit
The impact model
Surplus bread replaces a portion of barley malt in each batch: less land, water, and energy per pint than conventional brewing
Bread is diverted from landfill or low-value use (animal feed, anaerobic digestion) per unit sold
Profits fund Feedback’s campaigns for systemic food waste reduction at policy level
86+ breweries globally have brewed bread beer with Toast Ale’s method: the model spreads without Toast owning each production run
Investors cannot extract capital gains personally: return-seeking capital is structurally redirected toward mission
Why this business works economically
1. The waste stream is the cost advantage
Surplus bread is free or near-free. Barley malt has a market price. Replacing even a portion of the malt bill with surplus bread reduces input costs below any conventional competitor. Barley prices fluctuate with harvests. Free waste does not.
2. Mission replaces the marketing budget
Toast Ale’s “100% profit to charity” pledge makes every stockist pitch, media mention, and consumer story effectively free distribution. Tristram Stuart’s two decades as a food waste campaigner created an existing audience at zero cost. A conventional craft beer brand spends on advertising what Toast reinvests in impact.
3. “Equity for Good” attracts aligned capital
Investors include Heineken International, National Geographic Society, and former Unilever CEO Paul Polman. None can liquidate gains for personal profit. This structure filters out short-term capital and filters in partners who benefit reputationally from the association, not financially from exit.
4. B Corp score as procurement moat
Toast is the highest-scoring UK brewery on B Corp certification: 125.5 in 2024 versus a typical business score of 50.9. As ESG procurement standards tighten in corporate hospitality, public sector catering, and retail, this score functions as a barrier. Conventional breweries cannot replicate it without structural change.
5. The collaboration network multiplies impact without capex
Working with 86+ breweries to produce bread beer under their own labels means each collaboration is free brand distribution, proof of replicability, and evidence for policy campaigns. Each brewery becomes an advocate. The network grows the model without Toast growing its production.
The numbers
Over 4 million slices of surplus bread saved from waste since 2016 (figures to June 2025)
B Corp score: 125.5 in 2024, highest of any UK brewery (average business: 50.9)
£2 million+ raised from investors including Heineken International, National Geographic Society, and Paul Polman
86 breweries collaborated globally since 2016

Key insight
Surplus bread is not a storytelling prop. It is a free brewing input with real cost-of-goods implications. Toast Ale’s input costs are structurally lower than any brewer sourcing barley at market rates, and that advantage grows more valuable as ingredient prices rise. The charity commitment does not cost Toast commercially: it replaces the marketing budget and the sales pitch at the same time.
Why incumbents missed this
Large brewers optimised for:
Consistent ingredients at volume: surplus streams are variable, location-specific, and operationally inconvenient
Brand equity protection: associating a premium beer with “waste” felt like a downgrade
Shareholder returns: giving away 100% of profits is structurally incompatible with listed-company obligations
Scale efficiency: the model’s value only appears if mission is the goal, and incumbents had no mechanism to make it one
What it took to see the gap:
Coming from food waste activism, not brewing: Tristram Stuart saw surplus bread as a sourcing opportunity before he saw it as a story
Understanding that “100% profit to charity” could function as a commercial asset, not just a financial constraint
Recognising that craft beer consumers are exactly the demographic that pays a premium for credible values
Lessons for founders
A free waste stream is a cost structure, not just a story. Model the COGS before you write the About page.
Giving away profits can lower CAC. Quantify the PR and trust value before assuming the commitment is purely altruistic.
Capital structure innovation (Equity for Good) can attract higher-quality investors than financial returns alone.
Certified commitments (B Corp, profit pledge) create moats. They are harder to copy than product features.
The founder’s existing platform (two decades of food waste advocacy) was the distribution strategy. Audit what you already own before planning from scratch.
A collaboration network that spreads your model without your capex is a multiplier. Build it deliberately.

GlobeChain: Turns corporate surplus into a marketplace; the waste is the inventory, same structural cost logic as Toast Ale.
Final thought
Toast Ale is not a beer company with a charity angle. It is a food waste reduction vehicle that makes beer because beer is a category where consumers pay a premium, buy repeatedly, and talk about publicly. The surplus bread input is what makes the economics work: free ingredients against market-rate competitors is a durable margin advantage. The B Corp score and the profit pledge make the brand defensible against any well-funded copycat. The question worth sitting with is not why Tristram Stuart built this. It is why no large brewer looked at the cost structure and moved first.
