Chenin blanc (known also as Pineau de la Loire among other names) is a white wine grape variety from the Loire Valley of France.  Its high acidity means it can be used to make everything from sparkling wines to well-balanced dessert wines, although it can produce very bland, neutral wines if the vine's natural vigor is not controlled.  Outside the Loire it is found in most of the New World wine regions; it is the most widely planted variety in South Africa, where it is also known as Steen.  The grape may have been one of the first to be grown in South Africa by Jan van Riebeeck in 1655, or it may have come to that country with Huguenots fleeing France after the revocation of the Edict of Nantes in 1685.  Chenin blanc was often misidentified in Australia as well, so tracing its early history in the country is not easy.  It may have been introduced in James Busby's collection of 1832, but C. Waterhouse was growing Steen at Highercombe in Houghton, South Australia by 1862. Franzia is a brand of wine produced by The Wine Group, known for its box wines sold in 3 and 5-liter cartons.

In between are the regions of Anjou, Saumur, Bourgueil, Chinon, and Vouvray.
