Infection (I'm assuming)

[Donoroto]

I've left iodophor overnight in vinyl beer line tubing and it's permanently stained

Vinyl is far more porous than PET. Silicone will stain too. PET is pretty hard-surfaced.

I think I need to make an experiment!

That, good sir, is a pellicle and you indeed have an infected batch. Break everything down, clean it with bleach solution (1:10), rinse it and hope you get whatever bug caused it.

I use milton here in the UK. Its a sanitiser for baby feeding equipment. It's super cheap and works a charm! Not had an infection since

That's no rinse?there is steam too

 

[The Brew Mentor]

Steam or any temperature over 140° will melt or distort PET, so you'll need to use a chemical.

True yes sorry ignore me !
Bloody PET gotta be careful...

Never heard of this before, looks really good. Plus it's no rinse to boot. I resort to bleach when sanitizing plastic, but this looks better.

Yeah it's available in Australia.
I actually got given some for brewing from mum in law but I ditched it in favour for phosphoric Acid sanitiser.

I'll add its pretty hard at the homebrew level to sterilise
I think that's possible with autoclave but hey we're hombrewers .

 

[Kgbow]

Honestly never had a problem with it. I let my bottles soak in it for 15 mins. All fermentors and buckets and anything that is to come in contact with beer will soak in it! Works a charm. I even load it in my sprayer for quick jobs

good reason to go with stainless. I know it costs more. but you can pour in boiling water and then drop an immersion heater and keep it hot for an hour.

 

[Zambi]

Even we got Milton
Got a bottle somewhere. I'll check when I find it, but I recall it is just chlorine?

 

[BarbarianBrewer]

Milton's website says it contains 2% Sodium Hypochlorite and from the Clorox site it says it contains between 6% and 7.5% (concentrated version) of Sodium Hypochlorite. So, same thing but Milton's lower amount of NaClO makes it safer. Also why you need to soak for 15 minutes. So using @Nosybear's 10:1 ratio would bring the stronger bleach products down into a safe range.

In addition to sodium hypochlorite it contains @ 15% sodium chloride. I guess the combo is the difference.

 

[Nosybear]

The salt won't do much (sodium chloride). Rinse well - 3x in hot water is what's used for lab glass, should take care of the bleach residue on brewery parts.

 

[Zambi]

Mine is South African and contains 1 % sodium hypochlorite & 16.5 % sodium chloride.
Goes to show to always check the label. One Milton may not be the other Milton

This is good to know. I was leaning towards dumping based on other responses but this pretty much seals the deal for me. I don't need more headaches. Win most, lose some I guess. Just heartbreaking dumping any beer.

Definitely heartbreaking! Especially Oktoberfest. Sorry for your loss.

 

[naDinMN]

Sorry for your loss mate.
You've got a better win loss infection rate than I do.

Don't dump it! That looks like a Pediococcus infection, which is one of the beneficial ones. Pedio is what you need for belgian sours., for example. If it were me, and it was last fall with a Dunkleweizen, I'd save it and see what you get. Let the pelical finish forming and then wait for it to drop. You'll have a sour'd Marzen.

A good rule of thumb... White and off-white pelicals are good. Brown and black are bad. If you don't absolutely need the carboy it can be really fun to see what you get.

It is a persistent myth that these "infections" are hard or even impossible to kill. Modern science and testing has shown us that this is simply not true. I imagine, without proof, that the unkillable infection myth comes from the old days when we weren't using the best plastics when fermenting. The brew buckets and PET fermenters we have today a made of THE BEST food grade plastics. So, yes, Iodine sanitizer will easily kill off the infection.

 

[naDinMN]

So I took a small sample and tasted it and it does not taste sour. I can only assume it's done fermenting, so is there such a thing as racking it off the pellicle and then maybe bring it to a boil for a short period of time to kill the bugs and then putting it back into a carboy and then cold crashing it? Just throwing out ideas here in hopes of saving it.

It will take 6 months to a year for it to sour.
