If you have a 15 gallon pot with a false bottom why bother with the bag? sounds like you have a mash tun ready to go already. Perhaps I am missing something?A bag would allow me to remove the grain and then to do the boil in one kettle. The motivation
behind this is: Next summer we are planning on doing a 5.5 gallon all grain brew in the boundary
waters; canoe access only. We plan on brewing, fermenting, kegging/carbing and drinking it
before we return to civilization.
