I have made several AG batches and have a good crush so I know he crush is not an issue. I also hold water temp to a degree, so I know temp is not an issue. I also fly soar he at a slow rate, so I have come to the conclusion that it is something George my water. I have tried 5.2 salts and no improvement. I am not going to spend the money to test my water. I get an efficiency of around 50-60% and am getting super frustrated as I can never hit my target gravity. Anyone know what I can add to my water, aside from more grain, sugar or DME, which I have also done but don't want to do that as it just messes up thhe recipe. Maybe add gypsum or something else? I am planning on making a dogfish head 90 minute clone and it should be at 9% abv, but I am assuming I'll get it around 6% and will be really mad if I don't get it to at least 8%!
