Hello, that FG seems high, however, it would be helpful to know more about the exact recipe you followed. For instance, if you used a lot of maltodextrins, I don't think those are very fermentable and will increase your FG.

Hit all my volumes and OG numbers pre/post boil. Was withing +/- 1.5 degrees on mash temps. I saw a previous post someone was stuck on 1.030as well but didn't see how that turned out.
