Secondary Bubbles

[DaksBrew]

I fermented a LHBS "Dark American Lager" 2 weeks ago. I did it as an ale with California ale dry yeast. It spent one week in primary before I switched it to secondary. It had no bubbles in the airlock or on top of the beer when I switched and was calm until just now.

Now it has bubbles on top of the beer and I saw the airlock bubble. It seems to be fermenting more.

Is this okay? Is it normal?

It's fine. More than likely you racked too soon and it's somewhat active again. Nothing to worry about.

This is why you use gravity readings, not bubbles in the airlock, to gauge fermentation completion.

The bubbles may simply be more co2 gassing out as the room warms up 5 degrees on a sunny afternoon.

But without a gravity reading, who knows!?

I used gravity readings and they were stable before I transferred. The bubbles started like a week to 9 days after being in secondary

Unless you take another grav reading now you won't know for certain BUT an airlock bubbles for various reasons, change in atmospheric pressure, change in temp, the cat brushing against the fermenter, it doesn't mean anything whatsoever, just like airlocks not bubbling mean nothing. It's a vent, a valve to release excess co2. Change in temp means that more than likely the gas in the headspace has expanded, like gasses to often do when heated, or the change in temp is causing some of the co2 to come out of solution. That's why it's not a good idea to equate a bubbling airlock with fermentation, because they can bubble independently of fermentation, or not bubble DESPITE fermentation

Oh okay. That's makes sense. Thanks for the help!
