Type of variety
Classified as medium to large leaved, Riesling still fits in the 'hollandicum' group.
It is thus one of the most versatile varieties, allowing rather frequent as well as light defoliation.
Contributes strongly to high yields
Riesling not only supplies nitrogen to the grasses improving their yield, it also has a high proper yield.
The HCN content is average - enough to limit slug damage in most situations.
