Term (also known as destemming) for removing the grape skeleton (rape) or removing the berries from the grapes. This is to prevent the tannins, which are particularly unpleasant in flavour in green grape stems, from getting into the grape must. In earlier times, the grapes were mostly processed as a whole, as removing the stems by hand was too laborious and time-consuming. A "G'rebelter (wine)" used to be colloquially regarded as a special quality in Austria. There is also a "Viennese song" about it, which is often sung at the wine taverns (Buschenschank) in Vienna (Aber g'rebelt muss er sein).
In the past, you needed a wealth of encyclopaedias and specialist literature to keep up to date in your vinophile professional life. Today, Wine lexicon from wein.plus is one of my best helpers and can rightly be called the "bible of wine knowledge".
