I did my first 10 gallons batches yesterday (double brew day). Batch sparging. Both beers were similar estimated gravities. 1051 & 1046. My final volumes came out only slightly higher, but not bad as far as I’m concerned.
I have been consistently getting 71% efficiency for a while now. I got 78% and 79% yesterday. I’m really not complaining about higher efficiency, but I would like to know why, and would like to be consistent.
The only thing that was different yesterday was my mash temps held pretty constant. Only losing a degree or so. I’ve had problems in the past with losing as much as 5 degrees. The added volume and less head space in the mash tun really helped.
I also noted that my first running volumes were higher than expected, so I had to reduce my sparge water to get my desired boil volume. I used the same absorption ratio I always do and same crush.
Can anyone give me any insight into my higher efficiency? From what I read, I thought I may actually get lower.
