I watched a you tube video which confused me. Recipe was for orange creamsicle miklshake IPA, if you want to search for it. Recipe said it was for 5 gallon batch, used about 12 lbs of grain, target OG about 1.063. How they got there confused me:
They only started with 4 gallons in the mash, targeting 152F, and then used about 6 gallons of sparge water, so about 10 gallons of wort? They then only boiled for about 30 minutes, then shut off the heat and steeped for 30 with orange peel and hops, then chilled.
If I followed that process, I would be left with about 9 gallons and an OG of 1.045 or so. What step did I miss to get them down to 5-6.5 gallons of brew to ferment? I never tend to sparge that much as then I need a long boil off.
