So today is day 8 in the primary. I'm brewing a hefe and since my bubbling had came to a stop I would do a hydro sample to see if I'm done. I have never had any issues do samples on my last batch but this one I could not get a good accurate reading. Sometimes it would look like 1.020 and if I took out the hydrometer and put it back in the theif I would get around 1.015ish. I must have bad technique or something.
Most importantly I put the lid back on with the airlock so I could wash my secondary so I could rack it and when I came back down I noticed it started bubbling again?!?! I thought maybe it was a fluke bubble or something but I sat in a chair and watched for 3 minutes straight and got about 5 bubbles during that timeframe. So, I'm stumped a little. I'm going to let it stay in the primary fermenter for another 3 days or so and then I will take another sample to see if it had dropped any.
So basically I'm confused on what is going on. It had stopped fermenting, I go to check for FG and prepare to rack to secondary, when I come back and it has bubble activity in the airlock.
