Actually, I used 100% natural cider for one of the batches, and 50% natural, 50% pasteurized canned for the other, just to experiment. This year, though, I am looking for 100% real for all batches and plan on even trying a wild yeast batch.
You wouldn't happen to be a on the MontreAler list, do you? There was talk on that list about buying cider, but if they opt not to I would definitely like to participate in your buy! PM me and I'll send you my email...
