I’ve been brewing beer for almost a year now, and my set up is pretty basic. I have a 10 gallon kettle, a cooler mash tun, and a plastic bucket that doubles as a fementer and HLT. I also have my own grain milk. I’ve been pleased with this setup. My conversion efficiency is always near 100% and brewhouse efficiency is around 75%.
I’ve been toying with the idea of upgrading to a three vessel, single tier, automated HERMS setup. But something yesterday gave me pause in that plan. I brewed a spur of the moment BIAB beer using an old grain bag I picked up when I first started this hobby. I did a full volume mash with no sparge. I adjusted my recipe for a lower efficiency, which I fully expected due to the no sparge. However, my efficiency went up. My brewhouse efficiency in this BIAB batch was 85%. Gravitates were checked with a refractometer and verified with a hydrometer. I used brewers friend for the calculations.
So in summary, I shaved an hour or so off my brew day, my efficiency went up 10%, and I didn’t spend thousands on a complicated, difficult to clean system. If these kind of efficiencies are achievable with full volume mashes, without sparging, what’s the point of these more complicated systems?
