Met target SG - beer still fermenting

[Brewdogbrew]

Hello,

For latest batch (APA) I have reached target SG within 4 days (from 1.052 to 1.012). I still see active fermentation via regular release of Co2 through blow off tube.

What option is best:

1.) Let it continue to ferment until no signs of CO2 releasing resulting in a lower than expected Final SG?
2.) Cold crash it to stop fermentation?
3.) Any other suggestion?

Thanks!
Rich

Let it keep going and see if the gravity still drops. Do not attempt to stop it either way. You may not be seeing fermentation anyway. Bubbling only tells you there's a higher pressure inside the fermenter than outside. It doesn't intrinsically tell you fermentation is happening. Vibrations nucleating CO2, changes in barometric pressure, and especially temp changes can cause bubbling without actual fermentation.

As said above you don't really know if it's actually still fermenting or not, could be CO2 release. I'd leave it for another 6-10 days and check again.

Thank you both for the information. I appreciate it!
