I've just completed my first ever brew and everything seems to have gone ok apart from fermentation which seems to have stopped very quickly.
I used Safale SO4 which I know is a fast fermenter, but I pitched around 15:00 on Saturday (17th) and this morning (Mon 19th) there's no airlock activity. In between I had good fermentation and a healthy kreusen (sp?) was formed which has since dropped back into the beer.
The SG was 1.051 and this morning I had a reading of 1.016, which is very nearly in range of the recipe FG, but it just seems to have happened extremely quickly.
I made a starter out of 11.5 gs of yeast (this is for a 5 gallon brew) and also sprinkled a few more grams on dry to compensate for loss during a wee explosion in the starter bottle

When I took the gravity reading this morning I decided to sup the sample instead of chucking and it alteady tasted absolutley wonderful (very similar to Black Sheep). So I'm guessing everything is ok, but as a noob I'm just a bit concerned as to how fast everything has happened. Should I leave it in the FV for a while longer or just go ahead and keg?
Cheers for any advice
