According to this post:
I can get ~ 1.6 lbs of lactose to dissolve into a gallon of water. Now, I don't think I need quite that much, but I have read that somewhere between 0.5 and 1 lb is a good idea for my goals. (To make a potentially too-sour cider less so.)
My question is: should I just pour the lactose into the bottom of the pale, then rack the cider into it, to mix it up, or do I have to (potentially) add it to a lot (0.25 - 0.5 gallons) of water, boil that, then rack into that instead?
I'm looking to avoid making my brew too sour, but don't want to water it down, either.
