I am writing this post for all those who gave suffered with low efficiencies on their all grain systems.
I currently mash with a 52 quart rectangular cooler. For my grain bed filter I used a ss mesh that I pulled off a faucet hose and then clamped to my bulkhead. I typically mash in around 155F and check every 15 min o ensure I stay at temp.
I have been using the batch sparge method where I basically mix in water at 175F. I use a sparge water calculator on brew365.com. I the. Let the grain bed drain for an hour. I also do a vorlouf at the beginning of the sparge.
I have been getting very low efficiencies around 60% for my last 4 batches. All of my grain is crushed at the local brew shop and they claim their customers all get high efficiencies when having the shop crush their grains.
I have made a new grain bed filter and sparge arm out of cpvc. I chose this over PVC for its higher temp rating, however, those ratings are based upon having 100psi on the line. There is no pressure on the plumbing in an all grain system and I believe that PVC would work fine.
When I do my next brew I will update this post with the results of my new efficiency. I hope to achieve 80-85%.
