Default Why you should take off the blowoff when primary is done

Welp, just learned this the hard way. I made a tripel about 3 weeks ago and needed to use a blowoff (big one in a glass carboy.) We had a pretty good freeze in the last week and my brew room dropped to around 45 degrees and the temp change sucked back the nasty yeast/sanitizer/lord knows what water in the overflow bottle. . . I use a big honey jar and it sucked back probably 1/2 gallon of it. Needless to say, I don't think there is much hope for this tripel. Learn from my mistake. . .

I don't use blow offs. I use a large bucket and fermcap and never had a blow off that way. I also pour my airlock liquid out before cold crashing a bucket because of what you dealt with. Blow offs should only be on there until the krausen drops back down imo.

I use a blowoff on every batch and generally don't remove it til fermentation is finished.

Don't pitch it! I would see it through. Give it time to work itself out.

I use starsan and it was the second round. I generally dump the blowoff bucket after it starts to get a good layer of yeast. I suppose the extra volume would help dry it out some more!

How much starsan got in?? I betting not a whole lot....your probably fine. Think about it this way, it's okay to bottle onto starsan foam, it's okay to rack to kegs on starsan foam, its okay to rack from kettle onto starsan in your fermenter. I wouldn't dump it.

I always wonder why people put so much Starsan in the blowoff container. You only need enough to keep the end of the tube submerged.

I also say - don't dump it. If it was Starsan it probably only diluted the beer slightly.
