An Etymological Dictionary of the German Language/Annotated/Trester

by Friedrich Kluge

Trester, plural, ‘husks, grape-skins,’ from Middle High German tręster, Old High German trestir, plural, ‘grains, residue.’ The similarity in meaning to Treber, ‘grains,’ points to a primitive kinship of Old High German trębir and tręstir (compare also Anglo-Saxon dœrstan, ‘lees’), so that tręstir would represent *trefstir or *tręhstir. Prussian drag(illegible text)os, Old Slovenian drożdiję and droštija, ‘lees,’ which are primitively allied to these words, are also similarly related.
