Calcium sorbate as a solubility of 1.2%. Not so much compared to other sorbates but I guess it would still be effective since it's used as an antimicrobial.
As for the precipitation with a calcium salt, you would need a soluble calcium salt, like calcium chloride, not calcium carbonate or sulfate.
You should also know the exact concentration of potassium sorbate otherwise not adding enough calcium ions would leave too much sorbate in solution. Too much calcium would leave an unpleasant taste (bitter/extremely salty).
Well... just drink the damn thing.
