The Nederburg Heritage Brew Master is a classic Bordeaux-style red blend that commemorates brew master and tea specialist Johann Graue, who revolutionised winemaking in South Africa with his clonal selection efforts to isolate top-performing vines for reproduction and introduction of cold fermentation techniques. This wine is made from a blend of Cabernet Sauvignon (53%), Petit Verdot (20%), Cabernet Franc (19%), Merlot (6%), and Malbec (2%). The Cabernet Sauvignon and Cabernet Franc fruit was sourced from the coastal region, while the Petit Verdot, Merlot and Malbec were sourced from top-performing trellised vineyards in Paarl.
