The header says it all really. How worried about keeping good sanitation do i need to be when making turbo cider? seeing as cider can use wild yeast, there is no boil and so on. If i am grating up apples should i worry about introducing bacteria into the brew? I am halfway through making a small experimental batch and there does seem to be some musty off flavours, but this could be from the beer yeast i used; S -33 probably not the best choice in hind sight but i had it lying around.
