Hello, I'm new here. I've been wanting to get into homebrewing/cider making for a while and am just finally getting started. Unfortunately, I've run into a newbie problem before I can even begin.
I recently visited an apple orchard and bought a gallon of cider, but just now noticed that it says "preservatives added" on the label. I don't know what type of preservatives were used -- it's my understanding that ascorbic acid is fine, but potassium sorbate is not. According to the nutrition label, each jug (I bought 2 half gallon jugs) contains 135mg of potassium (as well as 60mg of sodium and 30g of sugar), so I'm afraid they may have used potassium sorbate.
Is there any way I can ferment this?
If I boil the cider first, would that help to neutralize the preservatives?
I have a pack of Wyeast 4766 and the packaging says there's enough for 5 gallons of cider. Since I only intend to ferment 1 gallon, would I be able to "overpower" the preservatives by using all of the yeast?
I'm hoping that I'll still be able to use the cider I already have, even if it's not ideal...
