Grenache blanc 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 characterized by high alcohol and low acidity, with citrus and or herbaceous notes. Its vigor can lead to overproduction and flabbiness. However, if yields are controlled, it can contribute flavor 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.

Grenache or Garnacha is one of the most widely planted red wine grape varieties in the world. It ripens late, so it needs hot, dry conditions such as those found in Spain, where the grape is believed to have originated. It is also grown in the Italian island of Sardinia, the south of France, Australia, and California's Monterey AVA, Paso Robles, Santa Barbara County and San Joaquin Valley.

The strong wood canopy of Grenache allows it to thrive in a windy climate but also makes mechanical harvesting and pruning difficult.
The thin skin and lack of coloring phenolic compounds makes Grenache a useful variety for the production of pale rosé
