Roussette d'Ayze

from Wikipedia, the free encyclopedia

The white wine Roussette d'Ayze is an autochthonous variety of Wine Country Savoy and is in the Appellation d'Origine Vin de Savoie as well as VDQS range Bugey wine grown. However, their distribution is extremely low. In 1999 only 2 hectares of vineyards were surveyed in France .

The variety produces quality wines with a high acid content, which are often used as base wine for the production of sparkling wine . It is mostly blended with the Altesse , Gringet and Mondeuse Blanche grape varieties.

The variety was first described by the ampelographer Paul Truel . Although it is listed as a separate variety in the growing areas, Pierre Galet believes that Roussette d'Ayze is just an early-ripening clone of the Mondeuse Blanche.

Ampelographic varietal characteristics

In ampelography , the habitus is described as follows:

  • The shoot tip is open. It is woolly hairy, the tips are greenish with a slight carmine-red tinge. The light green young leaves are slightly hairy and strongly spotted with bronze colors.
  • The small to medium-sized leaves (see also the article leaf shape ) are five-lobed and clearly indented. The stem bay is elliptical open, with the ends overlapping. The blade is serrated. The teeth are medium-sized compared to the grape varieties.
  • The cone-shaped grape is shouldered, small to medium-sized (it weighs an average of 175 g) and has dense berries. The round or slightly elongated berries are medium-sized (one berry weighs about 2 g) and greenish-white in color. The aroma of the berry is quite neutral, but sour.

The grape variety ripens around 6 days after the Gutedel and is therefore very early for southern French conditions, so that it can ripen in the mountainous regions of Savoy. Since it does not sprout too early, it avoids late spring frosts. The variety is sensitive to downy mildew and gray mold rot . It 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.
