Hi,
I'm struggling with the low efficiency for few batches now. I'm using fly sparge.
Today my conversion efficiency was 88.9%, preboil 67%, ending kettle 70%. My last batch was even lower, where ending kettle efficiency was 65%. I was expecting to have about 80% with the fly sparge (at least this is what I hear from other people using fly sparge - and they are getting as fas as 85% kettle efficiency). My mash was 60 C for 45 minutes and 70 C for 45 minutes. Also done mashout at 77 C. My pH was cca 5.6. I was using pilsener malt and carapils.
I was searching about bad efficiency but haven't found something to help me out (There most occured topic was bad crush. I'm using corona mill but I have adjusted the setting to get the very soft crush but not the flour). I'm using the electric mash tun. I'm measuring the temperature with digital and also classic thermometer. For the SG I'm using hydrometer and also refractometer. I'm measuring all my samples at the room temperature, that is 20 - 22 C. Fly sparge duration was 1 hour 30 minutes.
What efficiencies do you get? Do you know where could be the problem? Should I mash a little bit longer?
Thank You
