Fer (also known as Fer Servadou, Pinenc, Mansois and several other synonyms) is a red French wine grape variety that is grown primarily in South West France and is most notable for its role in the "Appellation d'Origine Contrôlée" (AOC) wines of Gaillac, Marcillac and Béarn but can also be found as minor component in the wines of Madiran, Cabardès and Bergerac. The grape is also featured in red blends from several "vin de pays" regions in the south west with significant plantings coming from the Aveyron department.
