I would suggest that you outline your exact methodology you are using....line by line in detail....which would allow us to review it and see if we can pick up on any issues or inconsistencies you have with your process.

This is what I did before my first all grain batch a few years ago and I got great feedback...that was very helpful for all grain brewing.

If your recipe estimate for OG is 1.052 and you are getting 1.030...then your efficiency is more like 40%....since most recipes are already based on 70% efficiency...I cannot imagine your efficiency is really that low though.

WHen you say your measured OG is 1.030 as an example you give....is that the pre-boil OG? Is that at 68 degrees F???

We will need more info....

P.S. Beersmith has a freee 21 day trial.....

I contacted Midwest and NB awhile back to ask if they would double-crush my grains for me (I do BIAB). Both said they could not, as they don't do custom crushes. I understand why--imagine the hassle if every order came with a specific crush. So I go to my LHBS and double-crush it there. I wouldn't be surprised if they ignore your request for a fine crush.

If you don't have a LHBS close by, I'd second the suggestion to get a mill. Then you might repeat one of your previous brews, keeping the process as close to original as possible to minimize variables, and compare results. Heck, post pictures here of your crush and see what the good folks think. If you still have an efficiency issue, then you have at least eliminated one variable.

Try mashing 1 lbs. Midwest ground 2 row in 1 gal of water you should get gravity around 1.037-1.038. If your gravity is lower then I blame the crush if it is within range then mash technique needs to be analyzed

Also Midwest should be able to verify the PPG of the grains they are selling

This. Lot sheets vary. I noticed many people use 38 for extract on 2-row when some of the more recent sheets I've seen suggest it's closer to 36. I've made some adjustments to my ingredients list accordingly.

Adam - I would strongly suggest that you buy your own grain mill. I had issues hitting my gravities also and I was even able to go to Midwest in person and grind my own grains!

This isn't a slam on Midwest at all as I still go there to buy by supplies.

Buying a Barley Crusher, watching my water volumes (insuring you don't leave wort in the mash tun) and checking the pre-boil gravity solved all of my problems. My efficiency is right at 75%, but that's not as important as it being consistent.

Are there any brewing clubs in your area? Or an LHBS that hosts brew days? Spending time with other brewers and sharing knowledge (real-time, not on the interweb) is invaluable.

My nearest movie theatre is an hour away. LOL. Not much here by the way of "community"

i'm going to get a grain crusher. Next purchase was going to be a wort chiller but you've all made it obvious I need to crush my own grain. Thanks all. I'm looking at the rest of my grain (I bought 4 batches worth at once) and it's all half milled. what a bummer. Should I just return it?
