I just purchased some new brewing equipment and I need some help creating the new equipment profile. The Mashtun is SS with a false bottom. There is 2.5 Gallons under the false bottom. I can pull all the wort out except .5 gallons. The weight of the Mashtun is 20.6 lbs. My boil Kettle is SS and 15 gallons. I can pull all wort out, except .2 gallons. any help is appreciated.
