I have done two extract batches over the last month and both finished about .04-6 points high. At first I blamed temperature then yeast then my process etc. But I know 100% not to sound cocky but it's not my process and the yeast may be the problem but i don't think so. I contacted my lhbs and they have know about these last 2 batch issues and finally suggested maybe it's either chlorine or chloromide that are causing the issue with it not finishing as low as it should have. something about gasses not pushing out or something. does this make sense and has anyone else had these issues due to chlorine / chloromides ?
