People have known how to make wine from grapes for a great 
many hundred years. In olden times, before wine presses were 
invented, and in many places to-day where they are unknown, the 
juice is obtained by treading on the grapes. The grapes are 
placed in large tubs with holes in the bottom, and people — men, 
women, and children — dance upon them, treading out the juice 
with their bare feet. 
In this country the pressing is entirely done by machinery in 
some form, and never by treading.
