I brewed up a porter a couple weeks ago, and though I was estimating an OG of 1.049, I got crazy efficiency and wound up with 1.062. I was using Irish Ale Yeast.
It's been fermenting since Oct. 26, but I noticed right away that the airlock wasn't going very strong. It had one day of mild visible activity, and since then, nothing.
Today was the day I was thinking about kegging it. I took an FG and got 1.021, not the estimated 1.013.
What do you think I should do at this point? I tasted it and it isn't bad. I could just keg it now. My hunch is that it won't ferment any more if I leave it be for another week, but am I mistaken? Or should I pitch another yeast pack?
