An Etymological Dictionary of the German Language/Trester

by Friedrich Kluge

Trester, plur., ‘husks, grape-skins,’ from MidHG. tręster, OHG. trestir, plur., ‘grains, residue.’ The similarity in meaning to Treber, ‘grains,’ points to a primit. kinship of OHG. trębir and tręstir (comp. also AS. dœrstan, ‘lees’), so that tręstir would represent *trefstir or *tręhstir. Pruss. drag(illegible text)os, OSlov. drożdiję and droštija, ‘lees,’ which are primit. allied to these words, are also similarly related.
