White wine grape · Vitis vinifera
A late-ripening white wine grape of the French Pyrénées, noted by both references for concentrating sugar while keeping high acidity.
Plantgrape describes Petit Manseng as originally from the Pyrénées-Atlantiques region and, based on published genetic analyses, closely related to Savagnin. UC Davis FPS independently lists France as its country of origin and Petit Manseng as its TTB-approved name.
Plantgrape describes small bunches of very small berries and says Petit Manseng is remarkable for its capacity to concentrate sugar while maintaining extremely high acidity, so it naturally produces aromatic, high-quality liqueur wines. These are attributed descriptions, not a harvesting prescription.
UC Davis FPS records that Petit Manseng FPS 01 (Tablas Creek Vineyard selection A) was donated to the public collection in 2010 by Tablas Creek Vineyards in Paso Robles, California, that the plant material is reported to be from a unique source in France, and that the original mother plants came to the United States through the quarantine program in Geneva, New York, in the 1980s.
Plantgrape describes Petit Manseng as vigorous and requiring trellising and long pruning, very resistant to grey rot, and late-season — about four and a half weeks after Chasselas at the Domaine de Vassal collection. These are reference observations, not management advice.
