About a month ago I brewed a Russian Imperial Stout OG 1.096 I used MR Malty to figure out the correct size starter and fermented it in the mid-upper 60s. Beersmith predicted my FG to be 1.022 but it has been stuck at 1.028 for at least 2 weeks now. Is 6 points alot to worry about? I know relax and have a homebrew but I just dont want any bottle bombs when I bottle this. Thanks in advance.
