What % Efficiency do you get batch sparging

RobertHSmith · Dec 26, 2008

As I have been refining my batch sparge technique, I have been getting better and better efficency. My last 6 gallons came out with 88% efficency. I have typically gotten with in a couple of points of 80 %, but never this high. Which got me thinking:

What efficiencies do other the batch spargers on this board get?

bluesman88 · Dec 26, 2008

I usually get 70-75%. I could probably make some adjustments to get that higher which I probably will someday, but for now I'm making real good beer and happy where I'm at with regards to efficiency.

Usually 85%+.

DrinksWellWithOthers · Dec 27, 2008

75%-85% depending on which malt and who crushes it. I just got a BC so I hope I can get a more consistent efficiency.

I just brewed a pale ale with 9 lbs. of Maris Otter, one pound of British Crisp, and one pound of American Two Row (they ran out of Maris Otter) and ended up with an OG of 68. I think that is an 83.5% efficiency. If so, that is the best I've ever done. Does that math sound right? It is a five gallon batch.

54-75 i still haven't nailed down a solid process nor a solid crush. should be able to get the crush in line very soon as i am gettin a custom built mill here soon. as for the process i think i know what i need to do but i want to see a few others brew be4 i make any drastic changes.

I've only done a few all grain batches so far, my first one was 60% eff but since then they've all been 75%-ish.

I just got a barley crusher for x-mas so I should be able to hit at least 80%

stevehaun · Dec 27, 2008

I used to get 80-85% mash efficiency using my non-adjustable schmidling malt mill. I then bought a monster mill and backed off my crush to 0.046 in an effort to get better flow thru my herms coil (and better temp control). It worked quite well but my efficiency fell to 75-80%. To me, this has been a good compromise.

big supper · Dec 27, 2008

Usually 70-73. I am not too concerned about going higher. I care more about the consistancy than being able to save a dollar per batch!

RobertHSmith · Dec 27, 2008

For comparison, I use a barley crusher at the factory setting. 10 gallon igloo water cooler mashtun. I ususally try to do everything in 2 batches.

vtbeerman · Dec 27, 2008

My homemade mill crushes at .042 and I get around 85% efficiency.

Zymurgrafi · Dec 27, 2008

I have a corona mill and I batch sparge. I have fiddled with the mill and gone from 60% to 70% and then the last few brews in the 80% range using a corded electric drill attached to the mill.

Saccharomyces · Dec 27, 2008

88% double batch sparge. My crush looks like rice hulls and flour now.

Bobby_M · Dec 27, 2008

My mash/lauter or "into the boiler" for you beersmithers is between 88-93% but I drop down to mid 80's for brewhouse due to losses in my external chiller.

modenacart · Dec 28, 2008

Mine are between 70 and 89% but I have been working on mash pH for a while now because I have very jacked up water.

desertbronze · Dec 28, 2008

I mash thin - between 1.5 and 2 quarts per lb. typically. Usually at 152 for 75 to 90 minutes. Runoff and 1 sparge. Typically 75-80% for beers at 1.070 and below - 65-70% for beers above 1.070.

sdhucks7 · Dec 29, 2008

For my first few AG brews I only got between 50 and 60% but yesterday I brewed a mild and lo and behold if my numbers are correct I hit 81% :ban:

Holy Crap how did that happen. I believe that since I took longer on my double batch sparge that is what made my efficency jump up (I was also sober for the first time the whole brewing process

)

80%

Right around 75%. However, my mash tun is getting upgraded. I have been having problems maintaining good temps so I am upgrading and getting bigger (10 gallon cooler). I am hoping this will get my efficiency up a bit. I am also thinking about moving to fly sparging though.

Beerthoven · Dec 29, 2008

85% efficiency.

Barley Crusher at 0.040 mill gap; 7-gallon round igloo cooler MLT; Single infusion mash, mash-out, single sparge.

stevo155 · Dec 29, 2008

I've been hitting around 55-65%, but my new Barley Crusher is on it's way and I'll be using the 5.2 stabilizer. Hopefully I can get this number up.

flyangler18 · Dec 29, 2008

Anywhere between 80-85%.

flowerysong · Dec 29, 2008

Right around 85% usually. A boiling water infusion to raise the mash to mashout temp, then vorlauf and drain first runnings. Sparge water is split into two batches, stirring after each addition (requires vorlaufing again to set the grain bed).
