Alentejo covers a huge, sun-baked plain in southern Portugal, historically better known for cork oak forests and wheat than fine wine until a wave of investment transformed it into one of the country's most commercially successful regions. Warm, reliable weather makes for ripe, approachable reds built around indigenous grapes like Aragonez (Tempranillo) and Trincadeira, often blended together, alongside a growing amount of fresh, easy-drinking white.
