Zaha operates in Mendoza, Argentina's premier wine region, where high altitude and intense sunlight forge powerful red wines. The winery's portfolio centers on Cabernet Sauvignon and Malbec—grapes that thrive in Mendoza's continental climate and volcanic soils. The Toko Vineyard El Corte, a Cabernet Sauvignon and Malbec blend, represents the winery's signature expression, earning recognition from Wine Enthusiast and Decanter. A single-varietal Toko Vineyard Malbec demonstrates the region's capacity for structured, age-worthy wines from this varietal. The Toko Vineyard Cabernet Sauvignon rounds out the core range. These wines reflect Mendoza's character: dark fruit intensity, firm tannin architecture, and the mineral precision that altitude imparts.
