At what point would I add the pectin enzyme?
Not sure if this matters but I plan on bottling around 1.02 (OG was 1.56) then waiting a few days and checking carbonation, once it's where I want it I will pasteurize the bottles. Would that make any difference?
There's got to be a typo in there... OG = 1.56 = sugar syrup with sugar in the bottom that forms crystals on everything... Perhaps you meant 1.056.. which is within the right range for starting out with store juice and a little sugar....
You can add pectic enzyme any time.
My typical recommendation for using Store jug juice is to supplement and/or backsweeten it with Apple juice concentrate rather than sugar. The more expensive "Organic" stuff works best in my opinion.. This helps add some "Character" back to the cider..... Otherwise, it ferments out pretty bland.
Thanks
