Honestly there isn't much chance anything can get into your blow off tube during active fermentation because there is so much coming out the tube. Before fermentation begins and after it ends you are at risk, but it's still pretty small. Things tend to fall down, not up. The spore would have to travel up into your tube and then back down into your beer, it's just not likely. Still best to use some water/starsan to be on the safe side.

That's what I was thinking. For sure here on out I will remember the sanitation in the blow off. I'm going to make the same batch and taste the two an see If there is a difference.

Hmmm. I'm glad I read this thread. It's been my understanding that sanitation is absolutely necessary n that without it my beer would become contaminated. Then again I am extremely new to home brewing. I love HBT!!

I use water in my blow off jug with a splash of Starsan. No infections yet.

It's a matter of linguistics. Take the following sentence:

"Wearing a bike helmet is absolutely necessary and if you don't wear one you will get a head injury"

What does it mean and is it true?

A question on Blow off bucket/bottles:

Should the carboy and BOB be on the same level (i.e., both sitting on the floor?) or should they be at different levels (one elevated on, say, an overturned milk crate or plastic bucket?)

Gracias.

I have the blow off jug sitting right next to the fermenter. But it's smaller/shorter than the fermenter,& it's water level is lower than the level of the beer in the fermenter.

If you get a chance, google Pasteur flask. That is essentially what you re making with a blowoff tube. Going in the air is ok, under water is better. With the right size tube it's no big deal either way. I have hundreds of gallons under my belt and so it's just MHO. Some sanitizer is prob. better, but one time without is fine.

A while back I brewed a porter in a bucket. My bucket is 7 gallons, but I didn't get the boil off I was hoping. So I put 6 gallons of liquid goodness in he bucket, pitched and sealed, and woke up to a bulging bucket. The CO2 could not leave the bucket quick enough. I tried a blowoff tube but my bucket system has a small airlock. So, I took off h lid and did "open bucket fermentation" for a day or so. Long enough to allow the pressure to subside but short enough so that there was still positive pressure when I put the lid back on.

It was a great brew. And I think it had nothing to do with that method

Good luck
