I did an AG pale ale batch today-8# 2 row,2#vienna,1/2 # crystal 10L-doughed in at 160-hit mash temp right on at 154 with 3.5 gals water,sat for an hour,vorloufed and x-fered to keggle,batch sparged twice with 2 gals/10 mins each time at 170,added 1oz cascade at 1hour,.5oz at 30,.25 and whirlflock at 15 and .25 at 5mins. 20 min cool and only ended up with 1.035 OG ?? Is this correct or am I dooing something wrong ? I did a batch of this a month or so ago and it turned out fantastic-I didn't deviate a bit from what was done then I just think the OG's a bit low----What do you all think ?? I'm curious. Shane

Yeah Brewsmith shows you as having 46% efficiency. Do you get your grains crushed for you or do you mill it yourself. Most likely if nothing else changed, it's the crush.

How many gallons did you end up with post boil?

Willsellout makes a good point too, I got a TERRIBLE crush from northernbrewer one time and got about the same efficiency as you just did. I added some DME to bring it up to par, but man, I was pissed at NB. Did you notice your mash seemed thinner than usual? I noticed that when I had a bad crush.

Well lets see, Judging by the side of my 6 gal.carboy-I believe I ended up with just over 5 gals.
Just after adding the second sparge the mash did appear thin/watered down....I never gave it a thought; I don't have any DME/LME on hand-guess I should've..
I'm in the process of building my own crusher-based on Yuri's pictures-My father-in-law works at a big machine shop just around the corner from me so acquiring the parts shouldn't be that tough;assy. should be interesting though. Shane

Yea, I suspect it was a bad crush. I got a little $50 corona crusher and it works just fine for me, kinda slow, but not too bad.

Can you guys elaborate on that crush problem? A too-fine crush may reduce OG? I'm a noob so this is new to me.

You can't extract the sugars from grains unless the husks are broken open. A bad crush in either direction could make your brew day go south. Not enough of a crush and you get poor extraction, too fine of a crush and you could get a stuck sparge/mash.

Wow, that is low. My LHBS always has a great crush, I am lucky, but I check it before I leave the store too. My AG Heffe this weekend was 81%, and my sparge got a little cold.

Not much I can do when it takes 9 days for NB to get my grain to me. I didn't notice how bad the crush was until I was mashing. Poored it in and all the whole grains were floating to the top

Why don't you buy a mill and stock up on grains?
