I brewed a PG IPA kit from Brewer's Best and had a great time with it. My O.G. after cooling to approxamately 75F was only 1.042 but I had a tough time reading it in the bucket. I followed the recipie exactly, and the wort tasted darn good once chilled! I also used city tap water for my make-up water which I don't think I should have done. It was very well aireated coming out of the faucet. Could the water / aireation have contributed to my low O.G.?
I'd really like a wort chiller, and a sight glass for my hydrometer. Wish me luck!
If it is an extract kit & you used the correct amount of water, the only possibility is poor mixing. Since all of the extract is actually in the fermenter, you'll get the correct ABV.
