1 Quart of Star San in 3 wk Fermentor

Noobie Screw up! I had a quart of star san mixture back flow into a carboy that had been fermenting for three weeks. I know, I can't believe I did it either. What should I do. wait and see if the yeasties will eat it? I was planning on bottling it tomorrow. Please Advise! Thanks!

 

If it was properly mixed, then all you've done is dillute your beer a bit. I'd be more worried if you sucked air back into the beer.

 

I would let it sit a while longer, maybe a week. I don't know if that will do anything better for the starsan incident, but I always try to leave my brews in the fermenter for 4 weeks if I can.

I would imagine that the starsan would dilute fully into the entire batch. Was this 5 gallons? If the starsan was correctly proportioned, its probably not enough to cause any flavors or problems.

 

More like four gallons, thats part of the reason for the backflow. Warning: put blow off tube and starsan below the level of the beer in fermentor especially when useing a plastic better bottle with ac unit ferm chamber.

 

tough lesson to learn but nothing bad will come of it.

 

Once your starsan came in contact with your yeast it pretty much ceased to be star san, and became yeast food. It breaks down into things that the yeast like.

 

Thats a relief, I'll give it another week or so and see how she taste. I made it purposely strong so i don't think dilution will be much of a problem.

 

Bottled it yesterday, tasted great. Pollen Pale Ale-OG:1.060 FG:1.008
