So with a 100lb mash you can pull off around a 40 finished gallon batch size with your mlt capacity. Is the 80 gallon boil kettle for safety room or so you can do a double mash and a larger 60+ gallon batch? Do you have a thread on your set up or more pictures? Im interested in your process and what kind of efficiency your getting out of it. Mine is a "40 gallon" kettle as well, not sure what the actual volume is though.
