I brewed a batch last night and put it in the fermenting vessel and put the airlock in at around 10:30pm. This morning I checked it at around 10:30am and the airlock has slowly started bubbling but I noticed that I didn't snap on the entire top of it. It's a 3-piece. When I noticed it I snapped it back on. I'm assuming this won't cause me any huge problems as it started bubbling but I just wanted to check on here to be sure. Anything I should worry about?
You should be fine. It sounds like the airlock was partially on so it's doing its job. You just want the bottom of the bell shaped piece to be submerged in your sanitizing solution. Even if it wasn't for a little bit you're still probably fine. This early in fermentation extra oxygen is not a bad thing and any sanitizing solution that got in there won't hurt anything either.
Primary: Pecan Sandy Porter
Barrel: a ton of brett
Tap 1: Belgian Saison
Tap 2: American Porter
in general you shouldn't worry, if fermentation kicked off as usual, chances are that nothing nasty got in your beer. keep in mind that there's professional breweries around the world that still ferment ales in open vessels. rdwhahb
Cool. The bubbling actually started faster than it normally does for me. Usually it takes closer to 24 hours for the airlock to bubble. This time I checked it 12 hours after pitching and it had started.
I think you'll be fine. I brewed 10 gallons the day after Thanksgiving and couldn't find one of my lids so just covered the bucket with a 10g round rubber maid cooler lid. Definitely not airtight. Took gravity readings from both beers last night and tasted each. They were both the same.. delicious.
