All Grain Brewing / Re: mash efficiency question
« on: June 14, 2013, 08:33:35 AM »
haha I wish it was red but in fact it is rather boring white on the outside (with my AHA sticker in front), green on the inside...I'm good on my water volumes as I always hit the right amount, just much lower gravity than expected, and I do batch sparge already...I think for the next batch I will:

1. get a new/better thermometer/hydrometer,
2. try double crushing and/or tightening roller spacing on my MaltMill, and
3. mash out/sparge slower

and see if that makes any noticeable difference to start...then maybe move into more detailed water composition investigations if necc.

thanks again for all the advice everyone, wish I started this thread sooner!

...and maybe time to invest in a new/better thermometer & hydrometer since I'm still using the ones that came in my starter brewers best kit...thanks for the feedback so far

yeah I should have said in my original post that I have a MaltMill and feel like I am getting good crush based on everything Ive read (hulls intact but everything inside grain pulverized). now I'm wondering if I need to check the spacing on my rollers, or just send it through 2x?

I'm not hung up on the efficiency number I just want to figure out why I'm not getting closer to what I should. one more step in the overall process...

All Grain Brewing / mash efficiency question
« on: June 13, 2013, 03:28:29 PM »
Ive been brewing for about a year and a half with good success. This is my first forum post. I did one extract brew and then moved on to all grain. Overall everything is going well but I'm having an ongoing question about my low efficiency (about 65%). I have been trying to eliminate variables one brew at a time but am getting frustrated when I think I have it figured out only to get similar results. I use a 48qt rectangular cooler mashtun and recently built a pipe manifold per John Palmer's instructions which came out great but didn't solve the issue. Ive been making a lot of similar RyePAs to try and figure it out...On average with about 11-12lbs of grain, single infusion 60m around 152df, and a 170df sparge, targeting around 1.055-60 OG. Usually I add some corn sugar or lengthen the boil to get the desired gravity which is fine but I've been asking around and reading the forum, re-reading the mash chapters in Palmer and I still can't figure it out. What do you expert all grainers think the most likely culprit is?

1. technique...mashing out/sparging too fast? should be a just above a trickle? the longer it takes the better?
2. water composition? I live in a rural area and the water is fairly hard, but we have a culligan system for the tap and a better drinking water filter system. I haven't done a fancy analysis yet cause I dont think this is a major factor. I use a combo of tap/filtered for mash and 100% filtered for sparge, and don't do any other treatments.
3. mash Ph? I've tested this a couple times and seems ok...
4. mashtun/equipment?

any advice or suggestions welcome and appreciated, thanks
