Stellar Winery, South Africa's largest producer of fine organic wines, processes just over 4500 tons of organic grapes for the South African and export markets. The grapes are drawn from farms straddling the northern boundary of the Olifant's River wine region and Namaqualand. This is an area famous for its spring flowers and is also the only semi-arid Biosphere hotspot in the world. Situated in the Namaqualand hamlet of Trawal, Stellar Winery is privately owned, with the workers having a 26% shareholding in the cellar and 50% in Stellar Agri - a table and wine grape farming operation.
