So I decided to brew my second batch and had a few complications along the way. I'm using a 8 gallon brew pot and filled it up to the 5 gallon mark(figuring after adding LME, hops, etc. a little would boil out, enough to come to 5 gallons in the end). Well, my wort chiller connection broke and after I finally figure out that I only had about a pound of ice, I ran to the store to get some more. After an hour and a half of my beer sitting around (including time chilling in a sink of ice and water), there was about 4 1/2 gallons of the chilled wort, about 70 degrees F. I added a little bit of cold water, and I then proceeded to take the OG. 1.032. About .012 from what I was shooting for.
Just wondering if possibly, after adding the extra water to the wort in the fermentor, if the OG could be off because I pulled from the watered down wort? I'm going to try and ferment at around 68 degrees in a bin of water, that I will be doing the old "frozen water bottle switch-aroo."
Thanks, I would greatly appreciate advice on bettering my homebrewing.
