The towns of San Nicolás, Portezuelo, Ninhue, Trehuaco and Quirihue are 70% rural, with small farmers cultivating non-irrigated, hilly plots of land. They traditionally produce wheat for their own subsistence, as well as wine grapes to sell. These farmers typically plant a quarter-hectare to a full hectare of wheat each year to produce straw that they can weave. Although due to the rise of modern, industrial farming techniques it has become less common to plant multiple wheat varieties, these planters have remained dedicated to biodiversity, planting varieties like Oregón, Milufen, Colorado, Milquinientos, Furfulla and Carrera. Such varieties are known for their long, smooth stems, their thin and uniform diameter, their even coloring, and their flexibility and firmness.
