I tried to search this but could not find a definitive answer - if you can point me to an existing thread please do, otherwise give me an answer!
I am making a simple hard cider (apple juice, apple concentrate, sugar, water, yeast). When it is done, I want to back sweeten with a simple sugar/cinnamon syrup and bottle it. I do not want carbonation so that is not a problem. I just dont want bottle bombs
LHBS guy sold me potassium sorbate, said it would stop the yeast from eating the back sweetener. Thats what I want. While searching around, I saw many posts that said you also need potassium sulfite.
So for this brew, do I need both?
