Bia Blanc

from Wikipedia, the free encyclopedia

Bia Blanc is a white wine variety . Although rarely grown, it is still one of the permitted varieties in the Savoie wine-growing region . The feinduftigen whites remember easily to a wine of the variety Sauvignon Blanc . Although mainly grown in the Isère valley , Jean-Louis Alléon-Dulac mentioned the grape variety in 1786 as part of the mixed set in the Côte-Rôtie growing region on the Rhône.

Ampelographic varietal characteristics

In ampelography , the habitus is described as follows:

  • The shoot tip is open. It is densely hairy with white wool, with a slightly reddish tinge. The greenish-yellowish young leaves are lightly woolly hairy and spotted bronze.
  • The medium-sized leaves are five-lobed and deeply indented (see also the article leaf shape ). The stem bay is lyren-shaped open. The sheet is serrated to a point. The teeth are set very closely compared to other grape varieties. The leaf surface (also called blade) is blistered and coarse in the area of ​​the stalk bay.
  • The slender, cylindrical grape is medium-sized and has dense berries. The slightly elliptical berries are medium-sized and almost white in color. The berries are very juicy.

The grape variety ripens approx. 15-20 days after the Gutedel and is therefore considered to ripen early. It sprouts quite late and thus escapes the late frosts. It is susceptible to downy mildew and gray mold rot . After the appearance of powdery mildew towards the end of the 19th century, their importance declined sharply. The vigorous variety is also poor in yield.

Bia Blanc is a variety of the noble grapevine ( Vitis vinifera ). It has hermaphroditic flowers and is therefore self-fruiting. In viticulture , the economic disadvantage of not having to grow male plants that produce yield is avoided.

Synonyms
