Hi folks. I’m looking for some advice. When pressing fresh grapes using my Lancman 250 l bladder press, I often get grapes slipping out the bottom of the basket in a glorious geyser of must. This happens most with white grapes with lots of labrusca lineage as the grapes are juicy and the skins quite slippery. I do use the green mesh bag inside. But grapes always blow out anyway. It makes a big mess and if you are in the way, you end up covered in grapes. Does anyone else have this problem? What have you done to prevent the blowouts? Thanks.
