I think my wine is in the MLF stage but I am not sure. I checked my gravity a couple days ago (a bit under 1.000) and racked off the lees and im still seeing tiny bubbles floating to the top of my carboy. air lock is bubbling ever so slightly. How do I know for sure that this is MLF and not some spoilage bacteria. Should I let it go till it stops or sulfite it now? I did taste the wine when I racked and it was hot with alittle haze but tasted pretty good. thanks people
