Rather than going to an orchard for cider, like I normally do, I decided to make a new batch using some apple cider I found in my local health food store. I used Zeigler's brand apple cider. The label said "no preservatives" so I thought I was fine, bought 2 gallons of it, and started a new batch this afternoon. As I was rinsing out the empty containers, I happened to read on the label that there was some potassium in it. A visit to the Zeigler's website confirmed my fear that they had added potassium sorbate to the cider as a preservative.
So now my cider has been sitting in the carboy for about 2 hours already and I'm worried that it's not going to ferment. Is there anything I can do?
In addition to 2 gallons of cider, I also used a cup of brown sugar, and a pack of Lalvin D47 yeast. My OG, if it matters, was about 1.05.
