From Dairy Farms to $50K Months: How Two Farmers Built a Thriving Coffee Side Hustle

June 26, 2026

Turning a Simple Idea Into a Business

Entrepreneurship often begins with solving a problem or improving something familiar. For Florida dairy farmers Dave Temple and Ed Henderson, that opportunity came from reimagining a common pantry staple: coffee.

The two longtime dairy farmers launched Thunder CoffeeMilk, a lactose-free canned coffee inspired by Australian-style iced coffee. Unlike traditional ready-to-drink coffee beverages made primarily with water, their product is brewed with milk, creating a richer and more nutritious drink. What began as a small side hustle has grown into a successful business generating between $40,000 and $50,000 in monthly sales, with projections reaching $150,000 per month by 2027.

Finding Inspiration Through Experience

Both Temple and Henderson come from multi-generational dairy farming families and have spent most of their lives in the dairy industry. Temple grew up on a dairy farm in Queensland, Australia, while Henderson studied dairy science at the University of Florida before continuing his family’s legacy.

Temple wanted to bring a popular Australian coffee concept to the United States. Together, he and Henderson saw an opportunity to create a healthier alternative to many energy drinks and ready-made coffee beverages on the market. Their mission was simple: build a product centered around quality milk and better ingredients.

Starting Small and Learning Fast

Like many entrepreneurs, they started with limited resources and plenty of determination. Their first product experiments happened in Henderson’s kitchen, which served as their initial research and development lab.

As the business progressed, they rented space at the Food Processing Innovation Center at Michigan State University to test recipes and develop a shelf-stable product. This required long road trips and countless experiments.

What made their journey successful was not perfection—it was persistence. They asked questions, learned through mistakes, and continuously improved their product and business model.

The Importance of Relationships and Mentorship

One major challenge was entering industries outside their expertise. While they understood dairy production, they had little experience in food processing, sales, or marketing.

To overcome this, they leaned heavily on industry contacts, co-ops, and trusted advisors. They learned that success often depends less on what you know and more on who you know. Building relationships with knowledgeable people helped them navigate challenges more effectively.

Their experience reinforced a key business lesson: don’t be afraid to ask for help.

Overcoming Challenges in a Competitive Market

Breaking into the ready-to-drink coffee market proved difficult. Established brands dominate shelf space, making retail entry expensive and competitive.

Marketing became one of their biggest hurdles. While producing a quality product felt natural, selling it was a completely different skill set. They quickly learned that great products do not automatically sell themselves—effective branding, positioning, and promotion are essential.

They also faced production challenges. Early product testing revealed unexpected chemistry issues, including milk solidifying during processing and protein clumping when frozen during winter shipping. Each obstacle forced them to adapt and improve.

Growth Through Persistence

It took roughly two to three years before Thunder CoffeeMilk began producing steady monthly revenue. Growth was gradual, but consistency eventually followed.

Today, their product continues gaining traction as they refine store placements, strengthen marketing efforts, and expand distribution. Their momentum suggests even greater growth ahead.

Lessons for Entrepreneurs

Temple and Henderson’s story proves that successful side hustles do not require perfect conditions to begin. Their advice for aspiring entrepreneurs is simple: expect obstacles, build strong relationships, and stay persistent.

Business growth is rarely linear. There will be setbacks, unexpected problems, and moments of uncertainty. But perseverance, adaptability, and a willingness to learn can turn a simple idea into a thriving business.

Their journey from dairy farms to a fast-growing coffee brand serves as a powerful reminder that sometimes the best opportunities come from reinventing what you already know.
