Bachet Noir

from Wikipedia, the free encyclopedia

The red wine variety Bachet Noir comes from the Aube department in the south of the Champagne wine-growing region in northern France . Jean Guicherd explains the name Bachet in his work Etudes d'ampélographie , published in 1905 . Monograph of the cépages de l'Aube. as a deformation of the place name Buchey , that is a place near Colombey-les-Deux-Églises in the canton of Châteauvillain .

The early ripening variety produces wines with a medium alcohol content and fresh acidity . When blended with the Gamay, it gives the wine more color and body.

The Bachet Noir is not allowed in any appellation . Small remnants (approx. 1 hectare ) can still be found in the Aube.

origin

A broad-based DNA analysis carried out by Carole Meredith in 1999 with 352 grape varieties suggests that the Bachet Noir variety is a natural cross between the Pinot and Gouais Blanc varieties. The same research showed that the varieties Aligoté , Aubin Vert , Auxerrois , Beaunoir , Chardonnay , Dameron , Franc Noir de la Haute Saône , Gamay Blanc Gloriod , Gamay , Knipperlé , Melon de Bourgogne , Peurion , Romorantin , Roublot and Sacy are similar like Bachet Noir all emerged from spontaneous crosses between Pinot and Gouais Blanc. Since the genetic differences between Pinot Blanc , Pinot Gris and Pinot Noir are extremely small, an exact specification of the Pinot type is not yet available.

The success of this spontaneous crossing is explained by the fact that the two parent strains are genetically completely different. While the varieties of the Pinot family presumably come from Burgundy , the Gouais Blanc was brought to France by the Romans. In the vineyards of Burgundy and southern Champagne, both varieties were mixed together for several centuries .

Lineage: Pinot x Gouais Blanc

Ampelographic varietal characteristics

In ampelography , the habitus is described as follows:

  • The shoot tip is open. It is whitish and slightly woolly hairy. The yellow-green young leaves are lightly hairy on the underside.
  • The quite large, bright green leaves are usually three-lobed and deeply indented. The stem bay is lyren-shaped open. The blade is bluntly serrated. The teeth are set wide in comparison to the grape varieties. The leaf surface (also called blade) is blistered and rough. In autumn the foliage turns completely red.
  • The cylindrical and elongated grape is usually shouldered and small. The round to oval berries are small and blue-black in color.

Bachet Noir ripens 5–6 days after the Gutedel and is therefore considered to ripen early in an international comparison. Despite its early budding, the variety is hardly endangered by late frosts in spring. The variety is sensitive to the genuine and downy mildew as well as the raw rot .

Noble vines normally have hermaphroditic flowers and are therefore self-fertilizers. Only a few noble vines, the wild vines and most of the American vines are dioecious. They have plants with male or female flowers. A male and a female plant are therefore always required for fertilization. Bachet Noir only has whitish flowers.

Synonyms

Bachet Noir is also known by the synonyms Bachet , Bachey , François , François Noir , François Noir de Bar-sur-Aube and Gris Bachet .
