Okay so I brewed a cream ale last saturday, a week and a half... 1.040 OG very weak because I ended up with 6.2 gallons after the boil. It is now at 1.012 and has been bubbling for hmm 8-9 days.... longest between bubbles was 15 seconds. I just took a reading and after disturbing it, its bubbling every 5 seconds. Ok, i put my sample in the freezer for a few min and tasted it, its kinda sour and still a tad bit sweet, it does not look infected at all... so im not sure why its a bit sour. I will wait for it to drop to 1.008 as it should, its still bubbling. and that's the estimated FG for 1.040 for this kit. Would anyone be worried at this point? I have brewed mostly very bitter hoppy IIPA's so this is the first BMC type of ale i brewed for BMC drinkers. I know I cant judge from this point but a tad sweet is one thing, but should it be sour at all? And will that mellow after 3 weeks bottle conditioning? Kinda scared.
