Please review and comment...I know this has been hashed out many times and I've searched and read many threads on this issue...
My OG was 1.054. My FG is sitting at 1.027 after 7 days in the fermenter...I know this is a somewhat early reading, but airlock activity has ceased. I know things continue, but I can't see it dropping 10 points to get near where its supposed to be.
First things first. I use a couple thermometers, with my gold standard for calibration being a glass lab thermometer. These are supposed to be the fairly accurate, although come to think of it I have never tested it with boiling water and/or ice bath. Should I do this. Everything I've read indicates they are the best to use, so I guess I never have. This could of course solve all my problems if it's out of whack.
So I nailed my mash temp and it held during the mash. Would dropping the temp a few degrees make a *huge* difference (i.e. the 10 points I'm lacking) in the gravity? I know lower temps make more fermentable wort.
For the yeast, I made a 2.5qt starter for the London ESB and it was nice and active when I pitched 24 hours later. I rehydrated and pitched the Notty at the same time. Fermentation temps were around 70 degrees.
Wort was aerated thoroughly with pure O2 for at least one minute.
I have always had a problem getting my FG to be spot on, but seems to be that I'm stuck in a rut with higher than what my type A personality deems acceptable. Don't get me wrong, all my beers have been drinkable beers with only one being overly sweet.
So I guess I'm looking for suggestions on what I might be doing wrong or need to tweak in my process. I might start making half batches until I can get this under control. In addition, if my FG doesn't move much more, what can be done. I have another packet of dry yeast. Should I make a small starter with it and get it going good and dump it in?
Many thanks in advance...
