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.
 
It provides a fairly neutral palate for the expression of terroir, vintage variation and the winemaker's treatment. In cool areas the juice is sweet but high in acid with a full-bodied fruity palate. In the unreliable summers of northern France, the acidity of under ripened grapes was often masked with chaptalization with unsatisfactory results, whereas now the less ripe grapes are made into popular sparkling wines such as Crémant de Loire. The white wines of the Anjou AOC are perhaps the best expression of Chenin as a dry wine, with flavors of quince and apples. In nearby Vouvray AOC they aim for an off-dry style, developing honey and floral characteristics with age. In the best vintages the grapes can be left on the vines to develop noble rot, producing an intense, viscous dessert wine which may improve considerably with age.
