In many countries it is or was an old custom to give the (overlooked) grapes remaining on the vines after the grape harvest (main harvest) to the public, or to allow this gleaning for certain groups of people such as the poor or children. In some wine-growing areas it was customary to deliberately leave some grapes hanging for the gleanings. In the Ahr and Moselle regions, the Glinn bell was rung at the end of the main harvest to signal the end of the harvest, the Glennen or Gelinnen.
In the Bible, Book of Leviticus 19.10, it is called upon to leave the gleaning to the poor and strangers. Regionally there are many terms: Afterbergen, Afterlesen, Ätzeln, Britschen, Glennen or Gelinnen (Ahr, Mosel), Granen, Grappern, Grappillage (France), Kluppbergeln, Leskornen, Nachähren, Nachwimmeln, Prapsten, Prapstlen, Prapstnen, Pritschen, Retzeln, Rispen, Rispeln, Schnaudern, Schnäuken, Schüweln, Spigeln or Spiegeln (South Tyrol), Spor, Stoppeln (Palatinate), Sücheln, Strumpfeln, Stupfeln, Tarlosnen and Wolferl suchen (Austria). To denote this, the words for the overlooked grapes (Leskorn, Stoppel, Wolf) were often combined with "suchen", for example Leskorn suchen, Stoppel suchen or Wolf suchen.
