Just wondering how you have increased your mash efficiency with your brewing system? I have been having some efficiency issues with my new system. For 5 gallon batches I am doing a single infusion mash, vorlouf for about 10 minutes after my timer goes off(35 minutes). My whole process takes about 30 to 40 minutes after sparging. I always keep water slightly above the grain bed. Usually about an inch. I’ve had some advice to never stir the grain bed while sparging, but I also have had some tell me to stir but to do so gently. One thing that I have also been concerned about is having the home brew shop mill my grain. I noticed my grain seemed to barely be crushed so I will be milling the grain myself. Hopefully these images work. Let me know what you think about the grain. I am using pumps to transfer. My efficiencies have never gone above 70%. This last batch was 60% The photo below is the grain of my last batch. I also included a photo of my mash tun. I do have the capability of 10 gallon batches but have been only doing 5 gallons to learn this system.
