Racked to soon?

I brewed a California Common over Thanksgiving weekend. It was my second batch (and the first full boil). I clearly learned A LOT while doing my first batch, as this one went much more smoothly, and I feel it's going to be a much better beer as well.

Here's the scoop. I let the primary fermentation go for a little over a week. It had slowed way down to the point that the airlock was bubbling once or twice a minute. I racked to my secondary (which went according to plan), and left very little head space. Now, two days later, I've got a small layer of foam on top of the beer in my secondary. I know the main reason for racking is to get your beer off the trub layer at the bottom, which I did.

But:
Did I rack a little too soon? Or am I just being paranoid?

Paranoid! It will be fine...... unless that foam is the "canadian beer death foaming pond scum" If it is whiteish you have a 97% chance that your brew will become acidic to the point that it will eat through your carboy. Oh! sorry, I forgot that you were already paranoid. It will be fine.....(I hope!)

I wouldn't have racked it if I still had airlock activity, but your brew will be fine. Stop being paranoid.

You just roused your yeast a bit, and not it's finishing its job. No problem there.


TL

Yes, you racked too soon.

No, it won't damage the beer. Just slow down the finish.

So, you didn't use a hydrometer, and just hoped that the airlock wasn't lying to you?

you probably did rack a little early. use a hydrometer, so you know that your fermentation is complete.
granted, you can 'get a feel' for when fermentation is done, but its still an educated guess, versus a scientific measurement.
