... 12 to 16 hours to brew and clean up, ...
Yea a keggle sized batch is about 12 hours for me. It starts at 7AM getting the chairs and stuff out from the Gazebo and moving the brew rig down from the shed. I get it all put back in place about 7PM. Then there's another hour or two cleaning up and hanging hoses, hop spiders and stuff to dry. Perhaps another hour the next day storing said hoses and stuff. So that's about 15 hours total. And then you have cleaning and racking to cornies two weeks later.
