You put in 099? That definitely it. I made a low gravity DFH120 clone and it came from 1.120 to 1.010 over 10 days. It stayed at 1.010 for at least a week as far as I know, then when I checked it before doing the dry hopping I got this.
Yeah I had to get my gravity down from 1.045. This was MONTHS ago though and I thought it would have stopped by now. So since the last time I checked it it was about a month. I'll let it go another month and see where it is. If it's the same then I'll bottle.
