As the heading states I will be attempting my first AG brew tomorrow. When I was doing Extracts and then PM, I never worried about water. I just purchased bottled spring water, and used that. My question now is, can I still do that with good results? I have tried reading as much as I can about water, and I feel like Im getting myself a bit lost, and want to concentrate more on procedure now. At the same time, I want to still be able to make good beer. Im brewing an APA tomorrow with 80% Pilsner. Should I do anything to the water, or just use it out of the bottle? Thanks.
