On a steep hillside in San Francisco’s St. Mary’s Park, nestled between the Alemany Apartments, the 280 Freeway and the Bernal Heights Neighborhood, there’s a wine vineyard that doubles as a teaching tool. A patch of land adjacent to Alemany Farm is being cultivated by Christopher Renfro and Jannea Tschirch, the co-founders of The 280 Project. Their aim is to use public land to grow crops and introduce people to the world of agriculture, with a specific focus on getting young African-American residents of San Francisco interested in viticulture.
