Low OG, But doesn't make any sense Options

[Billg]

I brewed yesterday morning....
8lbs 2 row
1 pound crystal
1 pound vienna
1/2 pound munich
1/2 pound pils
1 ounce N. Brewer 60 min
1/2 ounce casc 15 min
1/2 casc 5 min

I need to check promash to see what woul hapen if I only used 6 lbs instead (I had all three kids screaming so I question if I forgot the last two pounds.

Interestingly enough pre boil came in at 11 brix and at 80 degrees still 11 brinx (after boiling off 1.5 gallons).

This was the first time recirculating....but how could I have lost eff points? Gives me about 50% eff versus 75% for the past 90 batches?

Any thoughts?

Thanks,

Bill

Not possible. One of the two measurements was erroneous.

[Billg]

That's what I thought......so I gotta assume 1044 was the og as I took it with my hydro and calculated with temp correction.....but WTF was the og so low?

Impossible to say without some details. It might help if you post your brewing session.

[Billg]

heated mash water to 175
mashed for 45 minutes at 152
recirculated for 15 minutes
heated sparge water to 180
sparged at 170 and recirculated for 20 minutes
boiled for about 1 hour 15 minutes
grains crushed at bc settings as normal and looked finely crushed as is normal
turned boil aff at 5.5 gallons and let sit for 20 minutes to settle


That was my session....only difference was the recirculating which I have never done prior to yesterday....

I meant your ProMash session.

In the brewing session, click on the printer icon and then select "Copy to Clipboard". Then you can paste it here. Use [code] tags to preserve the formatting. Or if you can host web pages, export to HTML and then put it on your web server and post a link to it.

Notes
-----

tried recirculating today.  Came in low gravity at 1044 but dont know why..
..too little grain?  Did I measure wrong?

AS I RE-RAN MY NUMBERS .... 1045 WOULD HAVE BEEN CORRECT FOR 6 POUNDS OF 2 ROW ... SO I THINK I USED TWO POUNDS LESS THAN I NEEDED. WHAT WOUL YOU EXPECT FROM THIS BEER? SHOULD I MASH 2 POUNDS AND ADD IT?

BILL

I guess I could add some sugar or DME.... maybe 1.5 pounds of sugar?

I would leave it as-is. I think you'll wind up with a nice APA, albeit a little bit light in alcohol. The additional 2-Row would only give you more alcohol. If that's all you want, just boil some DME or maybe an interesting sugar and add it.

[MtnBrewer]

Sorry it took me so long to get back to this. I've been trying to see how many things I can screw up in one brewing session and still wind up with beer. (IMG:style_emoticons/brewboard/banghead.gif)

Anyway, I agree with Fletch. I wouldn't mess with it at this point. 1.045 is still a decent gravity. It's going to be more of a session type of beer but there's nothing wrong with that.

[Billg]

alrighty then.....keep it as is!

Thanks for the help guys!!!!!!!

I don't know how much help we actually were. (IMG:style_emoticons/brewboard/smile.gif) The brewing session didn't include the efficiency or water needed sections so I can't tell much about what happened. I'm going to assume at this point that you're right and you just left out some of the grain because you were distracted. In any case, it should be beer.

Remember to tie the kids to a tree out back next time. (IMG:style_emoticons/brewboard/wink.gif)
