Jacquère is an autochthonous white wine variety of the French region of Savoy and is widespread there. It occupies around 1,052 hectares in France (source ONIVINS), and the trend has stagnated since 2005. The variety was described for the first time on September 21, 1868. Pierre Tochon gave a lecture on viticulture in Savoy during a viticulture fair in Chambéry and wrote the description for the occasion.

The high-yielding variety produces fruity white wines with a flowery bouquet and, on very poor soil, a typical flint taste . It is sensitive to black rot and raw rot . By contrast, it is not very sensitive to the broadcasting rights - and downy mildew .

It is used as a blending partner in the white and rosé wines of the Vin du Bugey and Vin de Savoie appellations . Small stocks are also known in French-speaking Switzerland . In Portugal , the variety is approved in the Ribatejo and Oeste regions .

In France the clones 569, 629, 658, 769, 788 and 923 are approved for the aging of quality wines.

Ampelographic varietal characteristics

In ampelography , the habitus is described as follows:

  • The shoot tip is open. It is woolly hairy and slightly reddish in color at the tips. The young leaves with their bronze-colored spots are hairy like a cobweb.
  • The large leaves are five-lobed and deeply indented. The stem bay is open in a V-shape. The sheet is serrated to a point. The teeth are set closely in comparison to the grape varieties. The leaf surface (also called blade) is only slightly blistered and coarse.
  • The cylindrical to conical grape is medium-sized, shouldered and very dense. The round to slightly oval berries are medium-sized and green-yellow to golden-yellow in color. When fully ripe, the color tends to be very light red. The aroma of the not very juicy berry is neutral.

The berries ripen about 20 days after those of the Gutedel . According to international standards, it is still ripening medium-early, but in its homeland, the mountainous part of Savoy, it represents the uppermost limit of the berries that are still ripening.

It is difficult to grow. If the variety is not pruned sharply, yields can easily be 120 hectoliters / hectare or more, making it a mass carrier. In these cases the berries are undersupplied and as a result the winemakers achieve thin wines with high acid values. In order to achieve good wine quality, a targeted grape thinning must be used to reduce the yield.
