Hi, I've been doing all grain for about 10 batches now, and I have a question for any experienced brewers. How important is it to get the correct ammout of liquid in the mash tun? When I brew, I get about 5-6 gallons of water heated up to 160-165, fill my mash tun about half full, add the grains, stir well, then top it off with the same water. Then when I sparge, I use enough 170 deg water to get me up to 6.5-7 gallons for the boil. I've read that you should only use a set ammount for each step, depending on how many pounds of grain you use, but I've never had any trouble that I'm aware of. My beer always tastes fine. In my opinion, I'd rather use more water at the start than have to worry about adding purified/clean water to the fermentor to get an even 5 gallons. I don't follow the 'rules' for all grain exactly, but I've never had a problem. Why only 1.5 liters per pound, or whatever is the norm?
