New variety - VB 32-7
- General: The variety "VB 32-7" belongs to the new Piwi generation, bred in 1990 by the Swiss vine breeder Valentin Blattner. Its parents are an unusual duo. The red "Cabernet Sauvignon" and the Asian wild vine "Vitis amurensis" are the crossing partners and have a share in the good growing characteristics. As with "Cabernet Sauvignon", the berry skin is very firm and thus very resistant to botrytis. The "Amurbe" contributes to the resistance properties with a high fungal tolerance and frost resistance.
- Cluster: The cluster is rather small, loose-berried with small shoulders. The berry is round, small and covered with an even layer of wax. It turns golden brown when fully ripe.
- Wine: Aromatically, the wine of the VB 32-7 is reminiscent of the finer and more elegant variant of a white-pressed Cabernet when fully ripe. The nose reveals nuances of red pepper, fine spice to passion fruit and elderflower.
- Cultivation: The growth is strong and pendulous, which makes the variety interesting for inverted cultivation. Due to the rather dense foliage, partial defoliation of the grape zone is recommended in trellis training. The yield is rather moderate at 5 to 6 t per ha. The ripening time is comparable to Müller-Thurgau at the beginning of September. Due to the robust berry skin, the harvest window can be extended without rot becoming problematic. The early harvest time and the good frost hardiness make the cultivation interesting for northern wine regions.
