OK, I'm on my 4th all-grain brew and I thought I did everything correctly on this one but my Pre-Boil gravity came out really low. It was a very hot day here in sunny Texas, probably not the best brew day but you might have to wait a couple of months to brew in Texas to get down to the 80's.
Big question, are the temperature corrections for gravity accurate at high temps., otherwise I'm going to wind up with some lightly colored mouthwash!
It was an Amarillo Pale Ale with 9.66lbs of grain and wound up with 6.75gals of wort. I ended the sparge at 1.010.
Pre-boil OG was 1.018 @ 156*f which came out to a temp corrected gravity of 1.039 vs. the recipe's 1.042.
My question is if these temperature corrections are accurate at these high wort temps, because otherwise my pre-boil gravity was even lower.
I ended up boiling the wort for 30 extra minutes to try and get the gravity up a bit and wound up with a post-boil gravity of 1.035 @ 124*f(corrected for temp = 1.046) which was close to the recipe's 1.047.
Am I just being paranoid or did I screw up the batch.
