Oh S&%# - 1 gal of iodophor solution in the fermenter!

[alcibiades]

drink it in small amounts to see what happens, if nothing happens, drink it in large amounts

 

[nebben]

I keep trying to figure out what kind of color addition I can expect from 3ml iodophor ... Beersmith doesn't have an SRM listed for it... ideas?

 

[jensch]

I just did the same thing! Decided to pitch it and see what happens because the yeast would have gone to waste anyways, though I'll probably come to my senses and dump it tomorrow. I'm just still in shock and not ready to let go of my batch

If you had 1 gallon of 15 ppm, you now have 5 gallons of 3 ppm. The lethal dose of Iodine is 2-4 grams, and you've got 55 mg total in the whole 5 gallon batch.

I wouldn't be afraid to drink a pint or two as long as it tastes good. You're going to get approximately 1 milligram of iodine per pint.

 

[AggieChemDoc]

By the way, the body needs 12 or so mg of iodine per day. The only thing I'd be concerned about is what else is in iodophor. If it's PVP or some other stabilizer, you're probably still ok as that stuff just passes through.

 

[TXCrash]

I'd let it ferment and drink it if it doesn't taste too nasty.

I've sipped iodophor mixed at proper rates (curiosity) - it's nasty but wouldn't be so bad diluted 4x and with it's flavor covered up by beer. My prediction is that you'll have a medicinal flavor to your beer but that it'll be drinkable...

 

[jensch]

Well, my batch is 3 gallons of jamil wit and my first attempt at all-grain. It's fermenting away right now. I'll post the results when it's ready and I've tried it.

 

[Dynachrome]

...anything yet, or is it too early?

 

[cockybitz]

I bet it is fine. The stuff goes inert rather quickly. Then consider all of the CO2 produced in the fermentation and that further facilitates removing the Iodine gas from the solution. I say drink it.

When hikers use iodine to treat drinking water, the targeted concentration of iodine in the treated water is 4 - 5 ppm. So it sounds like you're within the acceptable range. Water treated like that tends to smell and taste a bit like when you open a box of bandaids - but it's not overwhelming. I dunno if it would be strong enough to be detected in your beer.

Some sporting goods stores sell iodine/neutralizers with their iodine water purification tabs... as a BSA leader I've had questionable creek water purified with iodine, it sucks... but after the taste neutralizer tabs it's not bad.... tastes a bit like chemicals.... but not bad. I probably wouldn't drink it but a neutralizer may help. maybe do an iodine test strip figure out if it's in the "safe range" and the neutralizer needed.... and then give it to your worst enemy... or my ex's new husband... to see if it's "safe" lol.

 

[jensch]

OK, I tried it. It's drinkable. Not amazing, has a slight bitter aftertaste on the middle of the tongue, but overall it still resembles a wit. Not sure if it's due to iodophor or the fact that it's my first all-grain attempt. Wouldn't make a night of it but a couple of glasses are OK. Hasn't made me feel ill at all.

So there you have it.

 

[Dynachrome]

Cool!

 

[devilishprune]

Check in tomorrow so we know you aren't dead

 

[Airborneguy]

wow... a little attention to detail really goes a LOOOOONG way in this hobby...

Iodine Toxicity

Chronic toxicity may develop when intake is > 1.1 mg/day. Most people who ingest excess amounts of iodine remain euthyroid. Some people who ingest excess amounts of iodine, particularly those who were previously deficient, develop hyperthyroidism (Jod-Basedow phenomenon). Paradoxically, excess uptake of iodine by the thyroid may inhibit thyroid hormone synthesis (called Wolff-Chaikoff effect). Thus, iodine toxicity can eventually cause iodide goiter, hypothyroidism, or myxedema. Very large amounts of iodide may cause a brassy taste in the mouth, increased salivation, GI irritation, and acneiform skin lesions. Patients exposed to frequent large amounts of radiographic contrast dyes or the drug amiodarone Some Trade Names

also need to have their thyroid function monitored.

Diagnosis is usually based on thyroid function and imaging test findings (see Thyroid Disorders: Laboratory Testing of Thyroid Function), which are correlated with clinical data. Iodine excretion may be more specific but is not usually measured. Treatment consists of correcting thyroid abnormalities and, if intake is excessive, dietary modification

 

[cockybitz]

We know that Iodine is a gas and that gases have a tendency to move out of solution.... especially when being carried out by continual gas production and expulsion of CO2 in fermentation. I already stated this. So if you started at XXX mg of iodine per ml, you can rest assured that that value is MUCH lower now.

Honestly, it probably isn't that big of deal. You said you had a gallon of 15ppm iodophor. So that's:

(1 gallon distilled water = 3.63kg.... 1 gallon of milk is 3.90kg, so I'll make the mass of the wort 3.75kg per gallon)

15 ppm = [(grams of iodophor in original solution) / (grams of total solution)] x 10^6

grams of iodophor = [15ppm(grams of total solution)] / 10^6
grams of iodophor = 15(3630**) / 10^6
= 0.05445g

** assuming the mass of iodophor <<<< mass of total solution


Now to find ppm of the final solution (assuming 6 gallons):

ppm = [0.05445g / (3750g x 6)] x 10^6
ppm = 2.42

The iodophor MSDS states the oral LD50*** is 14000 mg/Kg, which is equal to 14000ppm. You'll be fine

*** LD50: the dose required to kill 50% of a test population

...anybody watch "House"? On next weeks episode.....

What is the patient hiding?

Gregscsu, Have you ever been up to the Vine Park Brewery? I have not, but it's on my "Bucket List".

Hello everyone! I'm not dead.
However, that bitter after taste makes me not want to drink more than one glass. I may end up dumping a bunch just because it's not too pleasant.
I am still pretty new to brewing, though, so I can't be sure that the after taste is even the result of the iodophor.

 

[scruzgeek]

Just did something similar - it was dark, and I was going to re-sanitize the carboy because a b#$% slug had climbed up and was on the neck, and I didn't know if he'd been inside! I dumped a 1/2 cap into the carboy then remembered I couldn't fill it because the hoses were connected to the wort chiller.

Fast forward to wort temp 75 degrees, and I don't notice in the dark that there's some in the bottom... at least I'm pretty sure there is. It was hour 10 of two back-to-back 10gal brews. So I pour around 5 gallons of Brown Porter wort onto ~ 1/8 tsp of Iodophor.

Following this discussion, if 1/2 tsp / 5gal is ~ 12.5 ppm, that should put this at ~3ppm which should be tolerable. I pitched anyway, and if it doesn't take I can pitch again when the other carboy of 5 gal takes off using a sample of that and some DME to make a starter. Maybe I'll use this contaminated batch for the Lambic blend contamination experiment.

lesson learned, use starsan.

to the above poster, I think that small amount of iodine is fine.
