I know what your thinking.....Not another allgrain thread....I hate to beat a dead horse here but here goes. I went back and read the threads including all grain for newbies. I understand the concept. Just as Janx said once you see it theres nothing to it. Can you elaborate on the grain acts as a filter, I guess once the hour wait time is up and you start draining the wonderful sweet stuff you dont want to disturb the grain is this correct? And if you were making a 5 gallon batch, then once you begin to sparge once you get through you should have a total of 6 gallons or so, or at least enough to allow for evaporation during the boil, and by that time you should have sparged most of the sweetness out. I guess the part thats confusing me is the manifolds that I have seen at the bottom of the icechest what it the purpose of the manifold hot water up through the bottom?, or to catch the sweet stuff to be drained???? Bare with me here................
