Water Bladder Presses - The water press provides a very high yield of juice extraction from grapes, apples and fruit in general as the pressure develops evenly toward the external cage throughout the entire length. A rubber bladder expands from the stem outward using water pressure to press the fruit against the sides of the cage. Cage built entirely from 304 stainless steel with painted lid and basin. Press comes with pressure relief valves. Made in Italy with a  2 year warranty. Please note: The 160 liters come with a rolling cart.
