I just finished my third batch and it worked out great, this way works for making 2.5 or 3 gallon batches but in my opinion not 5 gallons unless you have a crane to lift that bag this recipe was pushing the limit.
I brewed a 3 gallon batch of the Lake Front Fixed Gear recipe 9.5 lbs of grain in 6.25 gallons of water and ended up after an 80 min boil with 3.25 gallons into the fermentor at 1.070. That’s 4 or 5 points higher than it should be but at 79% efficiency I won’t complain.
Start to finish took 4 hours that’s from setup to tear down and cleaning not bad looking forward to doing it again.
