Rice Hulls, 10 lbs.
These hulls or husks of rice are an effective aid in pressing grapes and other fruits. They improve internal drainage and make the grapes less slippery and less likely to shoot out through the slats during pressing.
They should be sprinkled over the crushed grapes as you fill the press. One 50 lb bag is sufficient material for 2 to 6 tons of grapes.
