The area also produces sweet and dry white wine and
sparkling wine under the two appellations Pacherenc du Vic-Bilh and Pacherenc du Vic-Bilh Sec, which cover the same area as Madiran AOC. The main grape varieties for the dry wine are
Courbu and
Petit Manseng, which together must make up at least 60%, and neither of which may exceed 80%. Accessory grape varieties (up to 40%) are
Arrufiac,
Gros Manseng and
Sauvignon blanc, with Sauvignon blanc being limited to a maximum of 10%. The proportions of grape varieties allowed have been modified in recent years, with the most recent changes being implemented in 2005. Previously, a certain proportion of Arrufiac was prescribed, and
Sémillon was allowed. Pacherenc du Vic-Bilh Sec, which are dry white wines, must be made from grapes with a minimum
potential alcohol level of 11%, and contain no more than 3 grams per liter of
residual sugar. Pacherenc du Vic-Bilh, without the "Sec" (dry) designation, is reserved for semi-sweet and sweet wines and must be made from manually harvested grapes with a minimum
potential alcohol level of 12%, and contain a minimum of 35 grams per liter of residual sugar. High-end sweet Pacherenc du Vic-Bilh wines are usually
made from dried grapes. == References ==
