I'm not sure if it qualifies as directly farm income but it is a great income, in the style of Sepp Holtzer. Where he makes money by doing something special, and high end, in very small amounts. Instead of trying to compete with typical mass marketed products.
The chef, waiter, gorager, grower (etc), never started off as one: "He learned how to cook from his mother, an avid gardener, and also from years doing odd jobs in mountain-resort kitchens in the Northeast. "I learned bits and pieces along the way, but I never did the research, never looked in a cookbook. In my family, we just learned to do it ourselves, and the inspiration came from nature," he says. After an injury in 1985 derailed his nascent career as a professional motocross racer, Baehrel and his wife bought their land and opened a catering business specializing in foraged food. It eventually morphed into the bistro concept in 2006 and since then has relied almost entirely on word-of-mouth buzz."
This hyperlocal, hyperunderground strategy is paying off. Baehrel won’t provide exact numbers but says he serves a few thousand guests each year and generates annual revenue of at least $750,000. By contrast, a successful restaurant in Manhattan’s crowded West Village might break the $1 million mark, though the business model is much different. Baehrel’s expenses are less predictable each season; they can include one-off big-ticket items such as a $5,000 trailer or a $10,000 hauling cart. But with no payroll or mortgage, and no food vendors except for his wine, seafood, and meat, which is from a local farm stand, he can stay both small and successful. "The biggest risk," he says, "is that it’s just me there."
