It has been 15 days since I brewed this Belgian IPA and for 2 days now I have gotten the same gravity reading of 1.021. The recipe says a final gravity reading of 1.010-1.015 should be expected but 5 days ago I got a reading of 1.030 so it has gone down since and seeming to level out. Any suggestions would be helpful. Just don't wanna have exploding bottles. Lol
