Grenache Blanc (also known as garnatxa Blanca in Catalonia) is a variety of white wine grape that is related to the red grape Grenache. It is mostly found in Rhône wine blends and in northeast Spain. Its wines are characterised by high alcohol and low acidity, with citrus and or herbaceous notes. Its vigour can lead to overproduction and flabbiness. However, if yields are controlled, it can contribute flavour and length to blends, particularly with Roussanne. Since the 1980s, it has been the fifth most widely planted white wine grape in France after Ugni Blanc, Chardonnay, Semillon and Sauvignon Blanc.
