I am doing 5 gallon mini-mash + extract boils now, so I am steeping for 30 minutes at about 150-155 in the first 2.5 gallons of water, and then putting the grains (in thir bag yet) in a collander in the top of my brew kettle and sparging with the other 2.5 gallons that I had been warming to 165-170 separately.
I know I've seen people design elaborate sparging wands, and was wondering what happens if I just pour 2.5 gallons of water through the grain? I don't DUMP it in form 3 feet away, but I probably pour the 2.5 gallons through the grain in less than 30 or 40 seconds. the water definitely runs out of the bottom clear afterwards.
Am I inviting clarity (chill haze) problems down the road?
