Hello all. I've taken to this site quite a bit and have learned a ton-enough to make me think I'm ready to take the AG plunge. I've gone through a lot, found a recipe I think is pretty easy, built a mash tun, determined boil off and heat loss rates (as best I can) but I've broken the number one rule of brewing-I'm not relaxing. I'm confused about water treatment\mash PH. I have a friend who swears by PH52 and uses the same water I'll be using. I've done enough research and it appear that stuff is utter garbage so I'm looking to the forums for some guidance. This first attempt is as much about making good beer as it is about learning what my brewing system can do. Do you all treat brewing water before mashing? Adjust mash PH while the mash is occurring? Both? Neither?
