I think one of my fermenters has picked up a nasty infection which I can't seem to get rid of.

I was using this fermenter to store some other brewing bits and pieces after brewing. I cleaned it out, filled it with water and napisan, and threw my spoon, airlock, racking hose etc in there. I honestly can't remember how long I left it sit there with that gear in it, except for the hose the rest wasn't being used. I'd say it sat for at least 2mths.

I finally went to use the fermenter again, I wanted to make a batch of ginger beer for the kids, I opened the lid up and went to pour everything out into the laundry sink, there was a whiteish film on top, and it appeared a bit like jelly suspended all through the water. I emptied it, gave it a good wash and left it to dry. When I went to sanitise it for my brew, I noticed it had a bit of a funny smell, I sanitised as normal with Idophor anyway, and then left it to dry afterwards. I could still smell that funny smell, so I decided to use some bleach, a little over a cupfull and filled the fermenter to the top leaving it to soak for about 3 days. I couldn't smell it anymore, so I made up the ginger beer for the kids.

The GB has been bottled for nearly 2 weeks, and they all seemed nice and firm(plastic bottles) so I decided to pop a couple in the fridge to test carbonation. Pouring a glass tonight, as soon as it hit the glass there was a huge smell, you couldn't get within arms length of the glass without smelling it. The GB also looked MUCH lighter in colour than I expected, it was almost clear, unlike previous batches I have made.

In the bottom of the bottle, there were some soft chunks that floated to the top after pouring, big chunks the size of a 10c piece, nothing like I have ever seen before with any of my other beers. I opened another bottle to confirm, and it also smells that way, and as soon as I opened it, I could see the bits start to float up off the bottom.

So, what have I got, and how can I get rid of it... After trying both Idophor and bleach, I'm thinking that I might be needing a new fermenter.

I've also got another brew in that fermenter going at the moment, it's an APA which has gone down from 1054 to 1030 in 2days and still tastes ok so far... I think.

Warm 1% Caustic solution or a new fermenter. That's the only way.

Did you rinse well after the bleach treatment?

Also, bust your taps apart - open them half way, stick the end of a wooden spoon down inside them and crack the other end of the wooden spoon on a hard surface while holding the tap output, then soak your taps in iodophor or bleach or caustic, or just buy some new taps for $1.50 each at Bunnings...
 
I am sure I rinsed the bleach out well enough, and I did sanitise with Idophor after that too.

Where can I get the caustic?

In the aisle at woolies - standard caustic soda. Watch out when using it, nasty stuff. Make sure you add the caustic TO water, not the other way round. Wear some rubber gloves too - make sure you get pink ones to impress the wife ;)
 
This is probably a good reason to store your gear DRY (after you've cleaned and sanitised of course ;-)
Germs hate dryness, but they love moisture.

Also, I like to give my fermenter a good sunning outside in full sun for a few hours after cleaning up - I find it helps dry it out and also removes any remaining smells. Upside down.

:beer:
 
Two months in napisan? That could be your problem. Or it could be an infection.

Napisan can leave a residual smell if not rinsed thoroughly with hot water. A two month soak means that smell is in the plastic. I don't think a soak with bleach is going to remove the smell quickly. Try filling with plain water and changing it every few days.

If it is an infection, a caustic wash should/may cure it. There are no gaurantees. Read all the safety precautions and follow them. Caustic is nasty stuff, a splash in the eye and no more eye.

Next time, soak everything in napisan, wash off and rinse thoroughly, air dry and store everything dry. Before you use the gear, use iodophor.

My turn to ask questions :)

Last night I peered into a fermenter and saw a distinct "whiteness" on top of the highest parts of some of the hops floating on the surface of the almost fermented wort.

Obviously this is some sort of infection.

The layer of hops is really quite thick as I dry hopped it with around 40g worth of plugs and as stated above I can only see very small white patches at the very top of the protruding hop flowers.

If it tastes ok from the tap (it currently smells ok) do you reckon I should just keg it, refrigerate immediately then carb and drink ASAP?

Also, it's for my birthday BBQ........what are the chances it'll make my guests sick? Any more sick than they usually get drinking my swill that is :lol:

It may not be an infection. Bubbles will naturally form on the nearest convenient place, this being the hops. If it tastes fine, it probably is fine.

However if it is infected, refrigerating it will impede the bacteria. Even if it is infected, it won't make anyone sick. An infected beer is more acidic than normal, sort of like vinegar. Vinegar won't make you sick (in small quantities of course :lol: ) It should be fine, don't worry.
 
If it's white and has a stirated or geometric formation and forms a film then its an acetobacter (vinegar).
 
I just took a closer look and it's not really white, more of a cream/tan colour like yeast.

I did use a top cropping ale yeast, so maybe that's all it is...just some yeast stuck to the hops and unable to floc out...here's hoping :huh:

I have a couple of beers that had a late infection thru racking, but it did not detract from the beer at all, rather it added an interesting flavour that can be benificial, especially in darker beers.. B)


Bleach or high does of Hydrogen Peroxide should help your problem..let the H2O2 sit for a few hours in the ferm..
 
I'm with the it'll be fine crowd. Are the hops flowers or plugs, fb?
 
Hey Stuster,

They were plugs, but obviously now heaps of rehydrated flowers floating on the top :)

Why do you ask?

PZ.
 
Thought it must have been plugs/flowers. The last (and first) time I dry hopped with flowers I got exactly the same thing. The beer is now two months old and no sign of infection so I'm sure you'll be fine. :super:
 
Sounds good Stuster,

I'm a big fan of plugs and only buy pellets if plugs of the required variety are not available, but I've only recently switched to Glad Wrap instead of lids on my fermenters...so maybe this has been happening all along and I just never had a clear enough view to see it? <_<

I just got an infection myself. I Found some small white worms in my racking tube after racking to a keg (50L). So there went my pilsner. Tasted horrible. So once i removed this from the setup, i cleaned the keg like mad and racked the last two esb australian draught kits available. All was fine until a couple of days after carbonating the taste had returned. Stupidly i had forgotten to clean the beer line and the infection had made its way into the keg.... What a waste of 70L of beer down the tap. Oh well learnt my lesson. My haste at trying to show off my new kegging setup to my mates kind of backfired. Lucky i have 2 lines :)
 
Worms? OMFG! :blink:

I'm assuming they were larvae...but from what?

PZ.
 
no idea. HBS guy knew what they were, some really long word ive never heard of. They were only about 2 or 3 mm long. Im now worried that the brewferm wheatbeer i have in the fermenter is going to pick it up as well.
