Olive Oil Production in a Cave or a Man Made Structure

Olive oil extraction process was often done in a cave or el or natural cave. It's because the olive oil itself needs a place to be stored with some climate control. A crushing basin would allow either man power or animal power to wheel a crushing stone around and around within that circular basin. The workers would then take the mash and put them into thin baskets called frails. And these very thin baskets would then be transported over to another implement within the gro which is the actual gethsemane, or the actual oil press.
