Craft Beer Meets Cattle: San Diego Ranch and Del Mar Brewery Partner for Sustainable Upcycling
A beef burger paired with a cold beer has long been a staple of casual dining, a combination that feels both timeless and effortlessly satisfying. Its appeal lies in its simplicity—the savory richness of the beef complemented by the crisp, refreshing notes of the beer. Yet behind this seemingly straightforward pairing lies a far more intricate story. Both ranching and brewing are deeply complex crafts, each requiring skill, patience, and a deep understanding of natural processes. In San Diego County, where culinary culture thrives on local sourcing and innovation, these two artforms are converging in a way that exemplifies sustainability, creativity, and community collaboration.
At the heart of this story is a unique partnership between a local brewery and a family-run ranch—one that quite literally brings the food system full circle. By repurposing spent brewing grains as cattle feed, the collaboration transforms what would otherwise be waste into a valuable resource, reinforcing the interconnectedness of agriculture and craft beverage production.
The journey begins at Viewpoint Brewing Company, perched above the scenic lagoon in Del Mar. Known for its diverse lineup of house-crafted beers, the brewery produces everything from the malty Del Martian Amber Ale to the aromatic Hop-Cano Hazy IPA and the traditional Das Chefeweizen. Each brew reflects both technical expertise and creative expression, embodying the spirit of San Diego’s vibrant craft beer scene.
But while the finished beers are celebrated for their flavor and quality, the brewing process also generates a significant by-product: spent grain. This material—composed primarily of barley and other grains that have been mashed to extract sugars for fermentation—remains rich in nutrients despite having served its primary purpose in brewing. For many breweries, managing this by-product can be a logistical challenge, often requiring disposal or limited reuse.
Rather than letting this resource go to waste, Viewpoint Brewing Company has found a sustainable solution through its partnership with Flying F Ranch, located in the rolling hills outside San Diego. Owned and operated by Alli and Bryce Fender, the ranch specializes in raising Black Angus cattle and emphasizes direct-to-consumer sales through online platforms and local farmers’ markets.
Flying F Ranch is more than just a beef producer; it is an immersive agricultural experience. The Fenders regularly host ranch-to-table events that invite guests to connect with the origins of their food. These gatherings feature multi-course meals crafted by local chefs, with dishes centered around the ranch’s beef and paired with selections from nearby wineries and breweries. Set against the backdrop of open pastures and grazing cattle, these events highlight the connection between land, livestock, and the culinary arts.
Integral to the ranch’s approach is its innovative feeding strategy. Once a week, Alli Fender travels to Viewpoint Brewing Company to collect the brewery’s spent grains. These grains are then transported back to the ranch, where they are incorporated into the cattle’s diet as a supplemental feed.

The use of spent grain is not only practical but also rooted in the biological capabilities of cattle. As ruminant animals, cattle possess a specialized digestive system consisting of four compartments. This system allows them to break down fibrous plant materials and extract nutrients from substances that are indigestible to humans. Within their stomachs, billions of microorganisms work symbiotically to convert forage and by-products into energy and protein.
This unique ability makes cattle particularly well-suited for upcycling agricultural waste. In fact, a significant portion of what cattle consume—estimated at around 90 percent—consists of materials that humans cannot eat, including grasses, crop residues, and food processing by-products. Spent brewing grains fit naturally into this system, providing a nutrient-rich, protein-dense supplement that supports animal health and growth.
For the Fenders, incorporating spent grains into their feeding program aligns with both environmental and economic goals. It reduces feed costs while enhancing sustainability by diverting organic material from landfills. At the same time, it contributes to the production of high-quality beef, reinforcing the ranch’s commitment to responsible agriculture.
Alli Fender describes the process as a form of “turning trash into treasure.” The cattle readily consume the grains, which she likens to a treat due to their palatability. Beyond the immediate benefits to the animals, the practice represents a broader philosophy of resourcefulness and stewardship.
From the brewery’s perspective, the partnership offers an equally valuable advantage. By redirecting spent grains to the ranch, Viewpoint Brewing Company minimizes its waste output and reduces the environmental impact associated with disposal. This not only supports sustainability initiatives but also strengthens ties within the local agricultural community.
The collaboration between Flying F Ranch and Viewpoint Brewing Company illustrates how different sectors of the food system can work together to create mutually beneficial outcomes. It is a model of circular economy principles in action, where outputs from one process become inputs for another, reducing waste and maximizing efficiency.
For the San Diego community, the benefits extend even further. Consumers gain access to locally produced beef that is raised using environmentally conscious practices, while also supporting businesses that prioritize sustainability. The partnership enhances transparency in the food system, allowing people to better understand where their food comes from and how it is produced.
Moreover, this initiative underscores the importance of innovation in addressing modern agricultural challenges. As concerns about food waste, resource management, and environmental impact continue to grow, solutions like this demonstrate that progress often lies in rethinking existing systems rather than reinventing them entirely.
Ultimately, the collaboration between a brewery and a ranch may seem unconventional at first glance, but it reflects a deeper truth about the interconnected nature of food production. From the grains used in brewing to the cattle grazing on open pastures, each element plays a role in a larger cycle—one that sustains both people and the planet.
In bringing together the crafts of brewing and ranching, Viewpoint Brewing Company and Flying F Ranch are not only producing exceptional beer and beef but also setting an example for sustainable practices. Their partnership serves as a reminder that even the simplest pleasures—a burger and a beer—can be rooted in complex, thoughtful systems that honor both tradition and innovation.
