I am getting ready to brew my first all grain batch, and I have some questions, I am in the process of building mash tun from a 10 gal. cooler and a cpvc manifold, I am using 13 lbs of grain, how much water should I add to the mash tun before I put the grain in? I know the strike temp is going to be 165 deg. but I cant find out how much to use, and the second question is how much sparge water to add and what temp should that be? I apologize in advance for the lame questions lol!
