The canned coffee aisle is crowded. Everybody knows that. And yet Dave Temple, a 55-year-old Florida dairy farmer, looked at it and saw a gap.
The insight wasn't algorithmic. It came from growing up in Australia, where iced coffee is brewed with milk instead of water — a richer, denser product than the cold-brew-diluted-with-dairy that dominates American shelves. Temple's bet was simple: Americans would pay for the real thing if someone actually made it. So he and fellow dairy farmer Ed Henderson started doing exactly that, roughly eight years ago.
Thunder CoffeeMilk now brings in between $40,000 and $50,000 a month. No venture capital. No viral moment. Just two working farmers who noticed that nobody had bothered to import the concept.
The Gap Was Always There
The product itself is almost aggressively straightforward. Lactose-free whole milk, cold brewed coffee, cane sugar, natural flavor, and organic caffeine from organic green coffee beans. That's the whole ingredient list. What makes it distinct isn't a proprietary process or a patented formula — it's the order of operations. Brewing with milk, not water, changes the texture and the richness in a way that no amount of added cream can replicate after the fact.
Temple and Henderson hit their first real retail milestone in August 2022, landing Thunder CoffeeMilk in select 7-Eleven stores across Florida. That's the kind of unglamorous distribution win that rarely gets written about — no splashy launch event, just refrigerated cases in convenience stores. It worked.
The manufacturing side forced an early and instructive pivot. The two farmers originally planned to use milk from their own dairies. It didn't pan out. Facilities capable of processing coffee and milk together are scarce, and the nearest viable manufacturing partner was too far away to make shipping their own milk economical. They ended up buying local milk closer to the plant instead. Not the romantic version of the story. The practical one.
Running It on the Margins of a Full Life
Here's the part that actually matters to anyone thinking about replication: Temple doesn't run Thunder CoffeeMilk full-time. Not close. It's one of three businesses he and his wife own, and in a typical week — outside of trade shows — he puts in somewhere between 10% and 20% of his working hours on it. Henderson handles production alongside him. The rest runs through a sales and marketing team.
That's a meaningful data point. Somewhere between $40,000 and $50,000 in monthly revenue, generated on what amounts to a fraction of one person's attention. The product does work that a service business can't — it ships, it sits on shelves, it sells while Temple is doing something else entirely.
According to Entrepreneur, the company projects monthly revenue of around $150,000 by the end of 2026 or into 2027. That would represent a tripling of current sales. Ambitious, but not absurd — the ready-to-drink coffee market has runway, lactose-free products have grown steadily as a category, and Thunder CoffeeMilk is already on shelves rather than still pitching buyers.
As of June 2024, the company was also planning to seek a strategic investor within 12 months, according to Axios. Whether that's happened publicly isn't confirmed. But the intent signals something: this was never meant to stay a side project forever.
What the Playbook Actually Is
The Thunder CoffeeMilk story gets filed under "side hustle" and "passive income" and all the categories that make it sound like an accident. It wasn't. Temple had domain knowledge — dairy — and a lived experience of a product format that didn't exist in his current market. He spent years developing it. He found a manufacturing partner. He got into 7-Eleven.
None of that is passive. But it is repeatable in structure, if not in specifics. The gap was a cultural import: something ordinary in one place, entirely absent in another. The execution was physical product, not software. The moat isn't a patent — it's the category awareness they built before anyone else showed up to the shelf.
Most people scanning that convenience store cooler have never heard of Australian-style coffeemilk. After enough cans move through enough checkout lines, that stops being an obstacle. It becomes the brand.
