Original Gravity WHACKED...
 
Did my first all grain yesterday. Yooper Pale was chosen. The pre-boil gravity wasn't even in the neighborhood. According to Beersmith it should have been 1.056...well I got 1.036. This was straight out of the boil pot after I stopped the sparge. Not sure if I needed to cool it first, not sure of what the temp was on it, but it was quite warm. Would the possibly make it read as whacy as it did?? I took a post boil gravity (after cooling the wort), and I got a reading of 1.050. Should I worry of RDWHAHB??:confused:

Your boiling water out there for your gravity rises..
What was your final boil volume?

I wound up with a touch over 5 gallons

Looks right to me if you boiled down from 7 gallons.. might be a mash effencey problem but it will come out just fine.. :mug:

Started with 6 gallons.

If you didn't cool the wort sample, your hydrometer reading will be off. If you were testing sparged wort, you could be looking at 160dg+, and I think hyrdrometers are calibrated for 60.

If that's the case, you pre-boil gravity was in the ballpark

1.050@5gal=1.042@6gal so your temperature would have been 100deg for the correction to be true at 1.036.. thats way under sparging temps.. something else must be wrong..
