... no, not antgravity!
So, for four days straight, my final gravity in my primary fermenter is at about 1.020. (taking samples with a sample thief.) I never took my original gravity reading, as this is my first batch, and in my rush to ferment and in my excitement, etc etc etc.
Per the kit, my OG was supposed to be 1.052, and my final gravity at 1.013.
I've done a few swirls of my primary... I am still getting bubbles every now and again in my airlock, but my stable gravity reading tells me that most likely fermentation is over. Or is it?
I am using Wyeast 1762, temperature has been stable at 68degF.
My only concern is my total volume... I know I didn't take into account boil-off, so I may have significantly less than 5 gallons. I have a 6.5 gal glass carboy as my primary fermenter; it is a total of 22 inches tall from the bottom of the carboy to the top of the spout - my total beer volume is 10 inches tall. Given a 12 inch diameter of the carboy, (and using volume of a cylinder equation) I estimate a pi(r^2) x height to give me 1131 cu in, or just about 4.89 gallons. Which means I'm about 12 ounces shy of the full 5 gallons.
My intent is, once primary is finished, to rack into a 5gal glass carboy for secondary for two weeks.
My thought is, perhaps I need to add more water to the system? 12 oz seems like a small amount to lower my gravity by 0.007. But I also don't want to blow bottles! Let me know if you need any more information.
