Thanks for the replies all. I looked at one recipe and it said the heat up 1.25 quarts per pound of grain. That would put me at about 4.5 gallons to start with. Then it said to rinse the grains after and not have more than 6.5 gallons to do the boil. I think I am still ok with that, right?
Also, my thought was, if possible, to add the water and steep the grains in the kettle. Drain the wort into another vessel, clean out the kettle and add the wort back in and do the boil. Then, cool the wort, drain into my fermenter and go as usual. My thought is, the false bottom will help strain some of the hop material out of the wort as it goes into the fermenter. Is this not a good idea? I was really hoping that this would be a nice all in one setup, but now I am thinking it isn't. I am still going to figure out a way to use it, but looking for the guidance of the experts. Thoughts?
