An Etymological Dictionary of the German Language/Kelter
Kelter, f. and m., ‘wine or oil press,’ from the equiv. MidHG. kęlter, kalter, m. and f. OHG. calcatûra, calctûra (also calctûrhûs, MidHG. kalterhûs); borrowed, on the introduction of the southern culture of the vine (see Wein, Becher, Kelch, and Keller), from Lat. calcatura, ‘wine-press’ (calcatorium), derived from calcare, ‘to tread.’ Hence Kelter orig. means ‘treading press.’ For the genuine UpG. for Kelter see under Trotte and Torkel (in Du. pers, AS. presse, from Lat. pressa). Kelter is MidG., and is found from the Moselle to the Saale. Corresponding to OLorraine chaucheur, from Lat. calcatorium.
