Designation (also de-stemming, rebelling) for the removal of the grape skeleton (centimes) or release of the berries from the grapes, This is to prevent the taste unpleasant, especially in green grape stalks tannins in the grape reach. In earlier times, the grapes were largely processed in the whole, as the manual removal of the stems was too cumbersome and time-consuming. A "gerebelter (wine)" used to be colloquially in Austria as a special quality. There is also a "Wienerlied" which likes to be played by the this year (Buschenschank) in Wien is sung (But he has to be agitated).
In modern viticulture, the stalk is no exception, but the rule. In the White wine almost always, at the Red wine production for the most part sank. At the beginning of the 19th century, mechanical devices such as the destemmer (Rebler) and the grape mill (Quetschmühle) were invented. In mechanical destemming, the grapes are conveyed by means of a spiked roller through a lattice drum, where the berries fall through. Only then is the squeezing means Traubenmühle, These two devices are sometimes switched in combination, where either one of the operations is also omitted.
Any unnecessary mechanical stress on the grapes should be avoided as far as possible, as this leads to increased sedimentation. Therefore, the need for skimming must be carefully considered. In a machine vintage The grapes are already beaten by the grapevine and the leaves and stems are removed by means of blowers. At the usual with the red wine maceration the stems are basically removed. In certain cases, however, no red berry is produced during red wine production. That's one Whole cluster fermentation the case, as with the techniques Macération carbonique and Macération semi-carbonique is common. Likewise, stay ahead of a special form of pressing - whole bunch pressing - grapes whole and unbroken.
Another criterion is the condition of the grapes. Fully ripe grapes for predicates have woody grape stems. Since these respect tannins are neutral, no discarding is required. This also applies to botrytised (rotten) grapes, because the dried berries dissolve badly from the stems. Scarves - Yes or No:
