Pearl from Alzey
The white wine variety Perle of Alzey was in 1927 by Georg Scheu in Alzey from Gewurztraminer x Muller-Thurgau crossed . In 1950, Hans Breider dealt with breeding post-processing through selection. Since then, the new breed is actually only called pearl . In 1968 plant variety protection was granted and in 1961 it was entered in the list of varieties . The information provided by the breeder about the parents of the cross has been confirmed by DNA analysis in the meantime. Although the skin of the berries is reddish to red in color, it is assigned to the white varieties in German-speaking countries.
The variety is very insensitive to frost and also suitable for problematic situations , the wine is relatively low in acid (→ acid (wine) ).

Ampelographic varietal characteristics
In ampelography , the habitus is described as follows:
- The shoot tip is open. It is very hairy with white wool. The young leaves are only hairy cobwebs.
- The small leaves are three to five-lobed and clearly indented. The stalk bay is U-shaped, open to closed, but rarely overlapping. The blade is bluntly serrated. The teeth are set medium-wide compared to other grape varieties. The leaf surface (also called blade) is blistered and rough.
- The cylindrical grape is small to medium-sized, mostly shouldered and dense berries. The round to slightly elongated berries are medium-sized and pink to reddish.
The grape variety ripens almost 10 - 15 days after the Gutedel and is therefore still considered to ripen early in international comparison. Due to the late budding, it has a low sensitivity to late frost. Pearl 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.
The variety is susceptible to powdery mildew and gray mold rot , but hardly to downy mildew . It also tends to paralyze the legs .
