The cost of a No. 4 Mabille press as illustrated below, with a 
6ft. x 6ft. cage, was, before the war, £25, with another £15 added 
for packing, railway and shipping freight to Fremantle, duty, and 
other charges. 
Continuous presses with a strong compound screen are also 
made; they give a greater extraction of juice, and require motor 
power for working.

Wine FERMENTATION,

transformed into wine.
