Leaves and grapes of the white Arnsburger grape variety

Arnsburger is a white wine variety . It is a new breed from Müller-Thurgau and Gutedel , which was made in 1939 by Heinrich Birk at the Geisenheim research station in the Rheingau . The breeder's original information that it was a cross of the two Riesling clones 88 and 64 has since been refuted by a DNA analysis by Myles in 2011. Plant variety protection was only granted in 1984 . In the same year, the Arnsburger was entered in the list of varieties .

It was named after the Arnsburg monastery in Wetterau in Hesse. The naming is a homage to the achievement of the Cistercian order in viticulture in Germany. In addition to a modest cultivation area in Germany, smaller plantings are also known on the island of Madeira and in Italy . In 2007, the area under vines in New Zealand was still stagnating at five hectares .

Due to its low susceptibility to the gray mold rot Botrytis cinerea and the Riesling-like fruitiness , the grape variety is also suitable as a base wine for sparkling wine .

The yield of the variety is slightly higher than that of Müller-Thurgau , but the must weight is five to eight degrees lower under comparable conditions . Arnsburger was one of the crossing partners in the new breed Saphira .

Ampelographic varietal characteristics

In ampelography , the habitus is described as follows:

  • The shoot tip is open. It is yellowish-green, lightly hairy and the tips are carmine-red in color. The young leaves are hairy like a cobweb.
  • The large leaves are clearly seven-lobed and bulged (see also the article leaf shape ). The stalk bay is seldom open in a V shape, but usually closed with a slight overlap. The blade is long and bluntly toothed.
  • The cone-shaped grape is large and wide, shouldered, long-stemmed and loose berries. The round to short oval berries are medium-sized and yellowish-green in color. The berries have a neutral taste.

The leaves turn yellow in autumn. Due to its medium maturity, the variety is only partially frost hardy.

The vigorous grape variety ripens around 15 days after the Gutedel and is therefore considered to ripen early in an international comparison. Arnsburger 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.
