Ampelographic varietal characteristics
In ampelography , the habitus is described as follows:
- The shoot tip is open. It is woolly hairy and has a carmine tinge. The yellowish young leaves are slightly woolly hairy.
- 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 medium-wide compared to other grape varieties.
- The cylindrical to cone-shaped grape is large and loose berries. The elongated berries are large to very large and golden yellow in color. The skin of the berry is thick. The crunchy flesh has a barely perceptible nutmeg aroma.
The variety ripens about 20 days after the Gutedel and is therefore considered to ripen early. Marengo is a variety of the noble grapevine ( Vitis vinifera ). It has hermaphroditic flowers and is self-fruiting. In viticulture , therefore, there is no economic disadvantage of not having to grow male plants that produce yields. The variety is susceptible to gray mold rot and therefore only plays a subordinate role in commercial cultivation. Because of the beautiful grapes, it is considered a favorite variety.
