Current automatic evaluation of the harvested grapes provided by the existing systems involves a determination of foreign bodies (stem, leaves), affected or damaged berries and unripe berries. However, the remaining healthy berries differ greatly in quality or ripeness, leading to different final wine styles. This article outlines how to determine suitable parameters correlated with grape and wine composition to be implemented as quality criteria for improving sorting methods of the grapes.
