Make quick work of crushing grapes with a stemmer-crusher. The rollers spin by manually rotating the fly wheel. Paddles within the hopper feed the grapes through the rollers, removing the stems and crushing the grapes. The stems are discarded throught the side and the crushed grapes are sent through the bottom. Requires a trestle stand to catch and funnel the grapes into a fermenter. Made of Stainless Steel.
