Hello all, I recently moved to all grain and have done 4 batches. I've been getting really bad efficiency like 50-55%. Here is my process, any help would be greatly appreciated.
I use a rectangular 52qt converted cooler with a CPVC manifold as my MLT.
I preheat it with 150F water for about 10 min, drain and dump my grain bill in. I mash pretty thin (1.5qts/lb) give it a good stir, take my temp (usually shoot for 155F) and close the lid. I stir at the half way mark (30min), take temps again and close the lid. I'm not losing a ton of heat, but I'd say that I lose 2-3 degrees after 30min. After an hour I vorlauf, carefully dump the wort back in the mash tun, and slowly take my first runnings (about 1qt per minute). I batch sparge after that, basically the same process, but shorter and less water involved.
Any thoughts why my efficiency is so bad?
