Porter FG 1.02

(1/2) > >>

Hi All - I brewed a True Brew Porter over 2 weeks ago. "Visible" fermentation lasted about 4 days. After that I saw no activity in the air lock but decided to leave it in the fermenter for a total of 2 weeks. After 2 weeks I took an FG reading and it was 1.02. Seeing as how the instructions said to expect an FG of 1.014, I decided to wait it out a few more days and took 3 more reading (each reading 1 day apart). All of the readings were 1.02. Convinced it was done fermenting I decided to bottle, especially because porters are known to come out a little higher in the end. Well, I opened one up after 3 days and of course it was a gusher. This happened with my first batch, but after the bottles had time to condition they properly carbed up. Even though, I still can't help but feel like maybe I had a stuck fermentation on my hands and didn't realize it. My main question is this - is 6 points off on the FG a big deal?? Could I potentially have exploding bottles on my hands??? Thanks!

With 2 weeks in the fermenter and a consistent gravity reading after that, I'd _guess_ it was done.  But I don't know how to explain your gushers.  Were the bottles cold when you opened them?  How much priming sugar did you use?

hmbrewing:
Hi Denny - thanks for the reply. The beers were warm and I used all the sugar that came with the kit. So I don't think it was a case of too much sugar.

denny:
Try chilling one.  CO2 comes out of solution much more readily in warm liquids than cold.  If you chill them, you may find you don't have gushers.

hmbrewing:
I'll give that a shot. Thanks again!
