So, I'm stepping up to AG very soon. I still need to get a burner, thermometer, and cut my keggle, but I'm getting there. I've constructed FlyGuy's 10G MLT from an Igloo cooler. I've read the sticky about efficency for first time AG'ers and I'm now more confused than I was before. I've read that I should not concern myself with efficency on my first AG batch, but eventually I will need to know and there is no time like the present. I want to do 5G batches. I will need to recalculate my boil off rate when I get my keggle up and going but right now I need 6G pre-boil to hit 5G on my stove top. I plan to batch sparge. Probably using the double sparge method. I now have no idea how much water to use. Should I sparge using recommended amounts and then just cut off the flow when I reach my desired amount? If I take the advice of the people who are getting good efficency then it sounds like I might be boiling for hours. Is there some middle road here?
