I'm brewing my first batch - a chocolate milk stout. All activity had ceased after two weeks in the secondary fermentor so I added the cocao nib/vodka mixture. The fermentation became active again and now, two weeks later, there is one bubble/minute coming through the air lock. My instructions imply that by this time I should be bottling.
Is it common for some fermentation to be going after all this time? Is one bubble/minute too much activity to bottle?
