Plug fell off Carboy

I brewed a batch Friday night. On Saturday my wife knocked off the plug on the carboy. It was probably off for a few hours, sitting on the floor.

I had to fill it again and then popped it back on. Its bubbling away, but I was curious if having it off for extended time then adding it back on is a no no?Obviously, it increases the risk of contamination. But I should be fine, right?

 

You should be fine. as long as nothing fell inside the carboy and you have good strong fermentation.

A lot of people (myself included) deliberately leave the carboy open for the first day or two of active fermentation, I usually cover opening with sanitized foil, and only then place airlock. For many saison strains people do open fermentation to prevent yeast stalling.

 

Thanks so much 55x11. Good to know!

 

I had a batch that blew the bung off three times! Beer is wonderful!
