Post your infection

no pellicule, just this weird alien lifeform on my Kveik last night pre-bottle. Tastes fine

That looks like mold. Should not be that powdery blue/green. I personally wouldn’t drink it as mold produce toxins.

As @Dgallo said, that bluish green powder surely looks like mold. That's never good!
(Well, maybe OK in certain cheeses).
Any clue how that could have developed? Did you add something to your beer while fermenting?

What are those yellowish looking kernels? Looks like corn...

is this still the main thread for posting potential infections or do you just make your own thread now? I've been away for a few years

This is more of a "showcase" thread, showing (beautiful) pictures of pellicles and infections.
Yours a good example of a mold infection.

You could start your own thread if you want more in detail discussion about it.

I just remember back in the day (10 years ago when I was active) there was like a yes/no infection thread instead of everyone creating their own, but I can't find it. Makes things more tidy doesn't it? If not, I can take this discussion elsewhere

No idea. They were squishy. There were a few more instaces of blue/green mold among the krausen but I still don't think all of the beer got infected, just whatever this was? Maybe a foreign body got into the beer before adding the yeast.

Nope, just pitched the yeast and let it ride for two weeks

Well, normally the thinking is that nothing that can hurt you can live in beer. I would not chance it though!

Did you scrape/ladle, pick those green mold patches off the top?
It's possible to remove them completely if they're floating on top, although the green dust may disperse somewhat. Maybe you can scoop that off too.

If that beer is done fermenting, you can probably package it by racking the clear/clean beer carefully from underneath the surface, while leaving the surface mostly undisturbed, and the trub on the bottom.

Give the beer a taste, maybe it's just fine. Just don't serve to others without first informing them mold grew on there, showing the picture above, and the potential health risk of consuming products contaminated with mold.

Something was or got into your fermenter or beer at some point, resulting in the green mold patches. Mold needs moisture and oxygen to grow, indicating the headspace CO2 was compromised. So review your cleaning and sanitation regimen. A dirty siphon or racking hose left damp can harbor mold, spores, and bacteria that get transferred, then grow under the right conditions, and voilà!

We racked to bottle bucket carefully without transferring any of the mold as it was floating on the top and we drained from the bottom tap. Beer tasted fine, and it will be only myself and my gf who drink it.

As for cleaning/sanitising, we're using Mangrove Jack's cold water detergent, rinse out and then Star San (no rinse). We pour directly from kettle into fermenter, no transfer tubing or siphoning.

I've never had issues like this in the past, the only thing I can't eliminate is the fermenter - it's a stainless steel one but it could be cheap quality? We also got a metallic staining around the krausen ring which I've not had in the past.

That was my thought too... corn.

Could be a aflatoxin. That's bad. Could be penicillium, that's okay. Could be a number of other molds that come in that color. Some bad some benign.

But I wouldn't be risking it. I'd have tossed if if that was in my FV.

If your fermenter is stainless then you should be fine. Use starSan at double the concentration and with 140*f water (wear gloves when it’s doubled) let it sit for 20 minutes. That should take care of it. Mold spores are airborne and only can live in o2 rich environments, meaning you definitely had o2 present in your headspace.

And your fv has to be open to the air when you add hot liquid, otherwise it can vacuum

Needless to say, but thoroughly re-check and re-clean everything that touches your wort (and beer). Then sanitize.

Perhaps a valve or port (treads!) wasn't quite clean, then the residue stayed damp and got moldy.
Gaskets/seals are also notorious for growing mold, tight spaces that stay damp.

Cleaners clean, sanitizers sanitize. There's no single treatment that does both in one and the same step.

Somehow after bottling I lay the bottle down for some reason I can no longer remember, when I go to check it after a few days I found something stick to the inside wall of the bottle and does not seems to be going anywhere. Are these infections as well?

That’s the yeast slurry/trub in your bottle. All yeast/trub with drip to the bottom of your bottles when bottle conditioning. Since you laid yours sideways, it collected on the side.

Now to say it’s infected or not, this picture wouldn’t be able to help you there because all microbes from the beer would drop out and be in this sediment, brewers yeast, wild microbes, and all

 

[Luxy]

Repeated by mistake. Message is one above Dgallo's reply. Thanks Dgallo & IslandLizard!

That's not an infection. It's sedimented (settled out) yeast, and other solids (trub) that were suspended in your beer when bottling. They always end up on the "bottom," which in your case is along the side now. They may slowly sink/slide down over time.

Although the trub/yeast is drinkable, and harmless, most find it unappealing.

To give you clear, transparent beer in your glass when pouring, avoid getting the trub in your glass. For that keep the side where the "trub" is on top, and pour gently, in a steady stream, without "glugging" or tilting back, until the bottle is nearly empty. Then as soon as you see trub appearing in the neck, tilt the bottle back quickly.

Third or fourth pull of a beer I kegged two weeks ago. Haven’t brewed in a year. Is this normal sediment or bad sediment I shouldn’t be drinking? They’re more like strings. It’s a dry hopped mosaic ipa. Very of putting to see but tastes good.

That looks like a pellicle, and a thick one at that. "Stringiness" often goes along with that.
Are you using a floating dip tube perhaps?

Most sediment (yeast and fine trub) will mix in with the beer when poured, and make your beer cloudy, sometimes with a little precipitation on the bottom. I've never seen it "float" like foam.

Thanks for the response. No floating dip tube. I’ve never seen anything like that either which is why I’m so thrown off on what it could be lol.

Are you bottom drawing with a tradition dip tube or do you have a floating? At cold serving temps I can’t imagine a pellicle growing that Quickly and if your bottom draw I can’t imagine your drawing any pellicle up as it only forms on the surface.

Bottom draw with traditional dip tube. Have it set at 38F. Maybe I’ll pull a few more pints and see if it continues.

Yeast?
Going by your picture, it does have the color of yeast... fluffed up with tiny CO2 bubbles. Just puzzling why it floats like that.
