You wouldn't by any chance have a few pictures of you Fly Sparging System, would ya?

Check the conversion of your mash and or its pH. Also, sparge with about 168 *F water and make sure you stir well after adding a batch of sparge water.

You have to also quote the OG of your recipe because the higher you go, the lower the efficiency numbers would be. Anyway, on my mid grav beers (1.040-1.060), I get around 88-92% with batch sparging.

I'd be looking at the crush and your sparge temps. Throw the thermometer into the mash right after you stir your sparge infusion in to get an idea how close to 170F you're getting. I use 180F sparge water.

I'd bet that fly sparging is NOT going to do much for you.

Have you checked you thermometer to make sure it was accurate?

I have the 72 quart coleman extreme with a stainless steel braid. On my first AG i hit around 63% efficiency with the Austin Home Brew supply crush. I did a dough in, mash out, and one sparge.RLinNH said:

On my second AG batch I hit 75% efficiency. The grains were also from Austin Home Brew supply but this time - taking advice from some people here - I skipped the mash out and did 2 sparges instead.

I've concluded that more sparges equals better efficiency with my setup.

Mash out and split my sparge into 2 batches.

I have checked the Thermometer, it is dead on accurate.

Here's what my Brew Day looked like...

Grain Bill

12 lbs UK 2 Row

10 Ounces 60L

10 Ounces Victory

8 Ounces Wheat Malt

2 ounces Roasted Barley

Target OG is 1.059

heated up Mash Tun with 1 gallon boiling water

Added 2 gallons of 174 degree water to Mash Tun to stabilize temp. Added all the grains while mixing, then added 2 1/4 gallons of 175 degree water to tun while mixing throughly. Brought temp to 162 degrees. (Grain was 69 degrees). Added 1 quart of 45 degree water to mash Tun while mixing throughly. Brought temp down to 147. Added 2 quarts of 180 degree water while thoroughly mixing, which brought Mash temp up to 153 degrees. Lit a Cigar

10 minutes into Mash, Temp at 154 degrees.

30 minutes into Mash, temp at a Rock Steady 154 degrees.

50 minutes into Mash, temp at 153.7 degrees.

60 minutes into Mash, temp at 153.5 degrees. Popped the lid and gave the Mash a thorough mix. After the Mixing, 66 minutes into Mash, temp at 151.9 degrees.

75 minutes into mash, temp at 152.1 degrees.

Added 2 1/4 gallons of 210 degree water, brought temp up to 153.3. Waited 10 minutes, then I sparged 1 1/2 quarts of Wort into a Quart measuring Cup, and recirculated.

1st Sparge, got 3 1/4 gallons of Wort (Sparged at 1 qt per minute). Looking to get 7 gallons total. Going to add Boling water next Sparge.

Added 2 gallons of Boiling Water to Mash. Brought temp up to 164 degrees. Waited 10 minutes after another through mixing, and did my second sparge. Again, sparged at 1 qt per minute. Now have 5 gallons of Wort.

Added 2 1/4 Gallons of Boiling water. Brought temp to 176. Got 7 gallons of Wort Total after this thrid sparge. Hydro reading of 1.046.

After a 1 Hour Boil, I had 5 1/2 gallons of Wort for the fermenter with a Hydrp reading of 1.056. That gave me an efficiency of 62.5%.

So, anyone see any discrepencies besides the initial water infusion? Any insight would be beneficial because as of this point, the only things I can come up with is that I am not getting a good enough Mash. I am going to have to start doing Iodine readings.

I stir every 15 minutes. How was the crush?

Crush was great. Used a buddy's mill. He gets 83% efficiency consistently.

I hear ya onescalerguy. I can not wait to order my new JSP Adjustable Mill tomorrow night so I can start experimenting with my crush. Still though, it boggles my mind to know that my buddy gets 83% out of his Mill. but he is also using a totally different Brewing system(The one where the wort runs through the HLT to keep a constant temp). Still though, I would imagine that I would be getting a better efficency then what I am. Obviously, that is not the case.

Next time you brew note the total amount of water you needed (strike and sparge), the pre-boil volume and how many times you sparged.RLinNH said:I hear ya onescalerguy.

Also check for conversion, make sure you sparge with ~170*F water and stir very well to make sure that there are no un-sparged pockets.

Have been hitting in the low 80's with the corona milled grains from my LHBS, but I have hit as high as 89%. I now have a BC mill and have only done one brew with it and got 76%. So I think with some tweaks on the mill I can get back up there.

I use 5.2 and that's about it. I just try to be very attentive to temps.
