Been reading all the threads and links to making your own ACV and cant find the answer to a question I have. I'm hoping someone clever here will know! I have been given 2 very big Scobys and I want to make my own ACV. I want to start with apple juice and not cider but everything I've read says the apple juice needs to be unpasteurized. 1. How do I know if its pasteurized or not? 2. How important is it that its unpasteurized? Any help really appreciated!
