Grolleau Noir

The red grape variety originates from France. Synonyms are Bourdalès, Franc Noir, Gamay de Châtillon, Gamay Groslot, Grolleau de Cinq-Mars, Grolleau des Mahé, Grolleau de Touraine, Grolleau de Tourraine, Grolleau de Tours, Groslot, Groslot de Vallères, Groslot Noir, Moinard, Moinard Noir and Pineau de Saumur. Despite seemingly suggestive synonyms, it should not be confused with the Gamay or Gascon (Franc Noir) varieties. According to DNA analyses carried out in 2004, it is one of the many direct descendants of the Gouais Blanc variety; the second parent is unknown. Somatic mutations with lighter berry colour are Grolleau Blanc and Grolleau Gris. In 1810, the variety was planted by a winegrower Lothion in Mazières-de Touraine, west of Tours in the Touraine area. At the end of the 1950s, it still occupied around 28,000 hectares, but since then the population has dwindled considerably. The high-yielding vine is susceptible to flavescence dorée and black spot disease. It produces light red wines with a strong acidity and is mainly used for the production of rosé wines. It is mainly grown in the Loire region, where it is permitted in the rosé wines of the appellations Anjou (main variety), Saumur and Touraine. In 2016, only 1,949 hectares of vines were still designated in France (Kym Anderson).
