Hey Guys,

I woke up this morning to a nice surprise. My airlock was full of yeast! I know this is a good thing, and I attached the airlock. Due to my inexperience however, I only placed the other half into a pot, without water. I think I can put the airlock in again, as things have calmed down a bit, but the fermentation is still active.

My question is how worried should I be about contamination since the other end of the blowoff tube was not in water?

If your fermentation was violent enough to require a blow-off, that means a decent amount of CO2 was being generated ad pushed OUT of the hose. It would be hard for microbes to travel against that gas flow and make it into your beer.

You should be fine, but if the activity has died off now, put the airlock back in.
