I Think...
I had an oatmeal stout with an OG of 1.060 then racked after a few readings of 1.026. Within a few days I had some yeast colonies on the surface and now there's a thin layer of foam on the surface (picture below). There is also some bubbles coming from the bottom that you can see on the side if you look closely (CO2 bubbles?) and there is plenty of airlock activity.
This is supposed to be a relatively low gravity stout but I still think the 1.026 that I had for a few days may have been a little high, which is why I think the fermentation is active again now after the yeast got moved around a bit.
Question is, how long should I wait before bottling? I'm relatively new to this an have mostly been sticking to the 1-2-3 routine and am worried about keeping the yeast around for too long. Should I wait for airlock activity to settle down before taking a gravity reading, or should I take one before? Also, is there anything that could cause the airlock activity other than fermentation?
