Hi! I know theres tens of these posts, but everyone has their own story and problem and how to solve it.
My problem was today, when brewing hefeweizen, I got only 55% efficiency! I use Brewersfriend software for calculations and it said my efficiency dropped from normal 70% to 55%.
First, my recipe:
1.25 kg wheat malt
1.25 kg pilsner malt
6.5L water on mash in, wanted to try ferulic acid rest so 43C first 10 mins.
Then added 5.5L boiling water to ramp it up fast to 66C. So 12L water now.
60 min rest. Temperature stayed on 65-66 whole time.
Mash Out at 76 for 15 mins.
No sparge, just pulled the bag up and let it drip over kettle. (Didnt drip much even when squeezed)
Got 10L of wort.
Got to rolling boil fast.
Hops in and 60 min boil.
Chilled with immersion chiller in 20 mins to 18C. After chill 8L wort left.
Added yeast and put it in fermentor.
I got estimated OG of 1.055 for 10L of wort in calculator, now got only 8L and hitted my OG.
Mash pH was 5.6 and my water was filtered with carbon filter (dont know if it affects anything but tried it.)
So.... Is this because of no sparge?
Or am I missing something else here?
I'm happy with 8L, but of course I want to always improve my brewing methods and get best value for money spent.
Cheers!
