Hey all,

Brewed an Indian pale lager today with the following grain bill:

9 lbs pale

1 lb carahell

.5 lbs Vienna

.5 lbs carapils

.25 lbs special b

.5 lbs cane sugar

After the boil I did a gravity check and came up with 1.056, which roughly equates to 70% efficiency. Here is what am doing.

Hydrometer works properly and all values are based on 60 degrees.

I mashed today with a ration of 1.75 qts per gallon instead of he usual 1.5

Grain was crushed using a barley crusher. Good mix of flour and broken husks

I batch sparge and mashed today at 148.

I’ve gotten close to 80% efficiency with my current system with several batches, but this is the second time in a row that I’ve been much lower than expected. The only thing that I can think of would be to drain the wort slowly out of my mashtun. I typically open he valve up all the way. Any advice or tips are appreciated.

Thanks
