After the Mash rest of said temp, Am I suppose to add the hot hot water BEFORE first runoff ? I've just emptied the MTL of it's original liquid,put that in the boil kettle, and THEN add required sparge water on the grain bed to hit the 170f . Is this proper, or ?
Yes, I recommend draining off first runnings before sparging but ONLY if you're breaking your sparge into two half sized infusions. If you're trying to sparge in a singe infusion, it's best that your first and second runnings are close to equal volumes. In order to do this, you'd add a bit of your sparge water just before running off. This is typically called a mash out infusion.
