I'm using this calculator for the sake of example: http://www.brew365.com/mash_sparge_water_calculator.php
So I will heat up all of my strike water. Then I put the mash water volume amount in my mash tun with my grain. I then drain off and recirculate until it runs clear. I then drain the water from my HLT through my sparge arm over the grain bed and make sure I match the flow to my wort out into the boil kettle?
Do I let the initial mash water sit with the grain for a set period of time before beginning this process? When do I start timing the mash? Do I need to stir the mash for awhile before I start the sparge?
Thanks for the help, I couldn't find a definitive answer.
