Traditional ratchet style presses are made with a pressed steel basin with an enamel coating. The basket staves are made of a hardwood and fastened with chrome plated bolts. Baskets are in 2 pieces for easy disassembly and removal of pomace. Also included are 6 hardwood blocks and two hardwood half-rounds to more efficiently and effectively press grapes and extend the reach of the ratchet. These presses come with a removable shaft which has a large nut on the bottom of the basin. The ratchet mechanism allows you to exert more pressure on the grapes than would be possible with a simple screw mechanism.
The "number" (#) of the press refers to the diameter of the basket in centimeters. There is no direct relationship between the diameter of the basket and the capacity in gallons or the number of pounds of grapes it can hold.
