So, I bottled my first beer last night. I have a bad habit of being hasty in all things, and it carried over into this endeavor. I made a BB RIS, and the target FG was 1.020 but my FG was 1.033 (OG was right on target at 1.082). There had been no activity in the airlock for about 60 hours, but I read today that it is a bad idea to use the airlock as a gauge of when fermentation is complete. I was concerned abou contaminating my beer if I opened it up every day to take a hydrometer reading, but I think I'm going to have to start doing that.
Furthermore, I didn't stir the mixture after siphoning into the bottling bucket (onto the priming sugar solution) because I couldn't remember if I was supposed to and the two homebrew books I had made no mentino of stirring, even though it seemed to me that I should. Later I found the recipe sheet that came with my BB kit, and it recommends stirring for one minute to mix in the priming sugar.
Lastly, two questions about yeast. I pitched dry yeast, and am wondering how much, and what sort of difference it would make if I made a yeast starter in the future. Also, I have a vial of yeast in my refrigerator for a Belgian Wit that I want to make, and I'm wondering how long it will keep before I shouldn't use it anymore.
