For my first brew I picked up a Brewers Best American Amber Ale. I followed the instructions and ended up with an OG of 1.050 which is right where the OG should be according to the paper that came with the kit. The problem is it does not have a FG number. It just says fermentation is complete when there is no bubbling in the air lock for 48 hours. Then it says to bottle. Well it seemed to soon to bottle and I took a reading and it was 1.020ish. So I let it sit another 3 weeks or so and the gravity has been hovering around 1.015 or so. This gives me a abv of 4.25 but, the recipe sheet says that I should end up with 4.75 abv. To get this I should have a FG of 1.012 or so and I am wondering after 3 weeks of the same reading is fermentation all done?
