Erlenmeyer flask rinsed in StarSan

For the first time I'm making a starter in my Erlenmeyer flask.

I soaked, emptied, and drained the flask pretty good save the foam that is normal. The funnel, bung and blowoff tube were also soaked.

I pitched the yeast in a DME solution at 11-12 brix.

Pretty standard stuff.

Is there any risk I'm going to kill my yeast starter considering any residual StarSan present in the flask.

With StarSan (really, with any no-rinse sanitizer), as long as you're using it at the prescribed dosage and draining your vessel well, there's absolutely no danger to your yeast. There would need to be a lot of sanitizer (like dumping your yeast straight into the sanitizing solution) to have an effect on it. Even that probably wouldn't kill it, though it would taste nasty.

So basically, you're fine. Just watch it bubble away.
