I screwed up.
I was worried about getting oxidizing my beer during the transfer to my keg so I kept the lid on my stainless steel fermenter and I left the blowoff tube connected and in about a 1/2 gallon of star san and water solution. Well I just opened up the spigot and let the beer drain not noticing that the 1/2 gallon of star san solution was sucked into the feremented beer draining into my keg! Crap.
I kegged it anyway (5 Gal) but has anyone ever done this?
If so, how did it turn out? Was it overly acidic or normal?

Any input would be helpful.
 
Half a gallon may make your beer somewhat more watery, but I doubt you could taste it, unless it's a very light beer in every sense of the word "light."

I've had a pint suck back once, and with another beer I racked on top of a quart of leftover Starsan in a keg. I never could taste any of it.
Similar situations as yours have been reported with no perceivable effects.

Sure if you put 2 glasses next to each other, one with a proportional amount of Starsan added and the other without, you should be able to tell the difference. Maybe not.

Lesson learned: Do not leave a blow off system connected when racking. Or cold crashing.
 
Been there. Done that. I had a pumpkin beer in my fermenter with a blow off tube stuck in about a quart of Star San. I cold crashed and woke up to an empty pitcher.

The beer was fine. But I’m probably never brewing that recipe again for unrelated reasons.

Homebrewed Pumpkin Ales can be really good!
I used 5 14oz cans of pumpkin puree (toasted for an hour or so!) in a 5 gallon batch and very little spice. It was pretty tasty and had a great color. Next time I'll double the pumpkin load.
