Abouriou (French spelling of Occitan "aboriu", early) is a red French wine grape variety grown primarily in Southwest France and, in small quantities, California. It is a blending grape that, along with Malbec, Cabernet Sauvignon, Syrah, Fer, Cabernet Franc, and Merlot, is used to make the "Appellation d'origine contrôlée" (AOC) wine of Côtes du Marmandais. Abouriou can also be made into a varietal, as it is used in some "vin de pays" wines. The grape is known for its low acidity and high tannin content.
