Bourboulenc is an ancient white wine grape variety with an origin of southern France, previously known under the name of Asprokondoura in ancient Greece. Most of the plantings are in the South of Rhône Valley and it is used in the Châteauneuf-du-Pape white blend adding structure and balanced acidity. It is also found in the La Clape region of Languedoc where it produces very rare fine wines from 100 per cent Bourboulenc worth of ageing. The grape is also used in Provence, Lirac, Tavel, Ventoux, Costieres de Nimes and the Vacqueyras appellations. Bourboulenc grows best in limestone and clay soils with a hot, dry climate. These conditions favour the grape to achieve the best level of ripeness and maturity. Outside France, it has been used in California as a varietal wine in small quantities.
