1st batch ready to bottle and.....MOLD

[unionrdr]

Well,since mold/yeast spores float in the air,usually settling downward,it seemed logical that they can't navigate their way through an airlock into the fermenter under normal circumstances. But with suckback,some force is being applied,so I can see where they might get in that way. But with no suckback,I rather doubt it,since spores have no cylia to move about on their own,like an anamacule does.

Ditto, Ditto, Ditto... taste and check.... I mean for mold to get going this fast I would think it was really infected prior... Posting a picture would be good....

Well, think of it this way. If you have a jar of olives, and you open them, take one out, and put the lid back on and then stick them in the fridge and forget about it, it will have mold on it eventually.

The lid is on the jar, so the mold didn't do any ninja moves. Just the unsealing of the jar, and exposure to air, is enough. It takes longer in the fridge, but it does happen.

Air exposure is a problem once fermentation slows- not just due to oxidation, but due to contamination issues from mold and bacteria (like aceterobacter or lactobacillus). That's why winemakers are very careful to always sanitize and to top up the wine in a carboy, and airlock it.

It does make me question how long the spores can servive in a co2 laden environment till enough air gets in to allow them to propogate?

The photographic evidence in this thread is overwhelming

Looks like it's cleared. Temp was up a bit and dropped the temp down pretty hard by putting it outside. It's gone.....My friend took a photo of before and after that i'm trying to get from him to post. I'm bottling this weekend.....Thanks for all the feedback.....i'm thinking this wasn't mold because not sure cooling it would kill it that quick.

yeah, my buddy swears by bleach and water in the airlock but now i'm thinking......if you get a vacuum, that batch is dead. I'm going to start doing the vodka for sure.

Why not star san? It's not going to pick up anything and if it does, it kills it, but it's safe to drink if you do get a vacuum in the airlock.

Vodka would work, but there are sugars in there and it will get nasty over time.

Yeast rafts/ left over krausen/ hop debris.

If a cold crash made it drop, it probably wasn't mold.

Agreed! I am glad it worked out for you!

Not if plain,unflavored vodka is used. I read up on distilling recently,& found out that the low ABV stuff is closer to first runnings. It gets more potent,as well as cleaner,with further distillings.
So plain,cheap vodka is fine for airlock usage. I've used it for quite some time now,as suggested by Gary from Home Brewer TV. He as a PHD,so I figure he knew what he was talking about. And it has def worked well for me so far. Never an infection in this regard. The cell walls of microbes can't stand up to the alcohol for long.

I too use star San in my air lock...

I quit using starsan in airlocks because as the airlock bubbles,the starsan foams up & goes out the lil holes in the airlock cap. It is then lost,& must be topped up frequently. The vodka,not nearly as much.

Another "I think I ruined my beer" thread put to rest. haha

Also I use vodka in my airlock.

Because of all the photos in this forum showing infections I have started to fill my secondary right up into the neck when I rack the beer. I am a big time believer that headspace is a bad thing.

I use starsan for all my sanitizing. The foam left behind after my violent shaking of the carboy (or even kegs) completely fills any deadspace I may have once it is filled up with wort or beer. This works for going from kettle to primary to secondary (although I don't do secondaries), to keg. Now if you are using the 7 gallon buckets for fermenting, it does remove some of the space but not all of it.

Another concern with the whole dry airlock deal is in the cooling of the wort. I am in Florida. The water coming out of the pops is 80 degrees much of the year. Even with my pre chiller on my wort chiller, I typically can't get my beer down to pitching temps. So it goes into the fermenter, and then into the fermentation chamber, with the airlock inserted. Of course, as the wort chills, the volume in the carboy contracts, and can completely suck the airlock dry. I just make sure I am checking my newborns every day to make sure their airlocks are wet.
