Greetings fellow homebrewers!

I brewed a batch of ESB last week and used my new carboy for the very first time. I used StarSan to clean the carboy. I shook the solution all around in the carboy then poured it all out. There were tons of large bubbles in the carboy. I tried to shake the bubbles out, turn it upside, all kinds of stuff but I couldn't get the bubbles out. Not knowing what to do, I rinsed it out with just a tiny bit of water. I know, I know, I shouldn't have but....

Anyways, is it okay to put the wort in there with the StarSan bubbles or should I let it air dry completely to try to get the bubbles to go away?

Thanks everybody!

Don't fear the foam.

I tinhk my fellow compatriates are so tired of re-answering this question, that they are only giving you a piece of the answer.

First off, no rinse, wet contact sanitizers like starsan and iodophor, are just that no rinse, wet contact santizers.

Meaning you do not rinse them and you rack you beer right on top of the foam or remnants of the sanitizer....if you rinse the stuff off, first you run the risk of contaminating what you just sanitized with the water....and if you drain or let the sanitizer dry you also reduce it's efficacy greatly..because although the next micro organism that comes in contact with the sanitized object MAY be killed, the object may more than likely now be vunerable to the next organism...or may no longer be sanitized at all.

Next in the case of the starsan foam, it actually is neutralized by the beer and becomes food for the yeasties. it actually helps in fermentation (an is even good for the bugs in septic fields)

You will find more info and links to the podcast from charles talley the inventor of starsan here...

Also, as you can see, when you rack ONTO the foam, most of it is lifted out of the carboy or the bottle that had it in the bottom.

And it looks pretty cool.

If it's not too late, I would go back and resanitize wit the starsan and rack on top of it...but if not, DO that next time...what's the point of spending money and time on the sanitizer, if you do not use it properly to begin with.

Thanks a lot Revvy. That's all I wanted to know. Next time I'll do it right. I have been keeping an eye on the carboy for the past week and everything looks fine. Nothing weird floating on top of the beer...just yeast. It smells fine too. I was just curious. Thanks a lot.

I figured out how to get the foam out. Use your thief to capture some star san. Press the nozzle against the neck like normal and deposit the star san into the carboy. Since it's not splashing it won't bubble up, but you will notice that it rinses away the foam in the bottom so it can be poured out. Repeat until no foam remains.

I don't fear the foam, but I don't like a lot of it because of the mess you see in Revvy's picture above. I keep my starsan in a bucket and siphon a gallon into my carboy when I want to sanitize it. Then I put a plug on the carboy and gently roll it around to get all the surfaces wet without making a lot of foam. Then I carefully pour it back into the bucket not letting it just glug out of the carboy. I usually get very few bubbles if I'm careful.
