We have owned this press since 2006 and it is a work horse, never letting us down. We are retiring it and moving to a larger press. Holds 1 ton of whole cluster grapes or 3 tons of fermented red grapes. We replaced the bladder about 5 years ago. Great for a small winery or one just getting started. Single phase, simple to use. Service from Prospero. The hopper is custom built for this press.
