Hello everyone, I've been AG brewing for a few years now and have always had very low efficiencies (55%) and am looking for ways to improve this.
I've read the sticky on efficiency improvement and believe I'm covering the bases.
My latest grain bill was 12lb pale 2row, 1 lb munich, 4oz cl60. I believe I got a good crush on the grain, but I'll buy some pre crushed to double check next time. This is a 5g batch where 4.5 made it into the fermenter after leaving some trub in the kettle.
My OG reading came to 1.052 which is around 55% according to brewers friend... Here are my mash notes:
15 Quarts strike water at 170F, stirred in water and grain at the same rate, leaving no clumps. Mash came to rest at 150F which I left for 30m, added a quart of 170F water and brought it up to 154F for another 30 minutes.
Recirculated a couple gallons before starting a fly sparge with 5gallons of 180F water (cools to about 170F by the end of the sparge). I matched the inflow and outflow to keep water just above the grain. Wort collection took 30 minutes to complete.
First Wort Runnings: 20 Brix or 1.083
Last Wort Runnings: 5 Brix or 1.02
Pre Boil wort: 11.5 Brix or 1.046
OG: 13 Brix or 1.052
I'd like to get this up to around 70% if possible. All suggestions are appreciated.
