I currently brew with 3 keggles. It seems to me that you should be able to use one of the stock equipment templates in BeerSmith to get started. You can then take the closest one to your system and save as and edit it to dial in your system. First figure out how much dead space is in all your vessels i.e. when your mash tun and boil kettle are fully drained how much is left over. Do you do fly or batch sparge with equal runnings? I assume you are doing all grain. If you start plugging these numbers into the program and figure on 65-70 % efficiency it should get you in the ballpark. This would be “YOUR equipment profileâ€. From here you should be able to use one of the mash templates in the program or you can make your own custom mash schedules based on what you are brewing i.e. single infusion, 150 degrees 1.2 qts. of water per pound of grain etc. Everyone of the templates can be saved as and edited. It still will take you a few brew days taking copious notes to tweak. Sometimes you won't have enough wort, sometimes you will have a lot left over. Sometimes your mash will be too thick or thin. Hope this helps.
