Wish I could help you out but I brew it seasonally. Sept - Nov I get juice directly from the orchard so I have nothing worthwhile to add about store bought juice. DJF makes some from store bought, perhaps he will chime in.
Cheers,

Yeah, DJF mentioned his use of store bought juice on the Applejack thread earlier this week. I thought I would try responses to store bought juice on this thread and see if we could get a few responses.
