Cabernet Sauvignon – Malbec is a blend of two dark red grape varieties, both originally from the vineyards of Bordeaux. While Cabernet Sauvignon is still widely planted there, Malbec has found a new home in the high-altitude vineyards of Argentina. The Cabernet Sauvignon – Malbec blend is usually produced there, making dense, tannic wines with plentiful red and black fruit characters.
