I am still confounded by the "star san is expensive" argument.

I mix up a 2 1/2 gallon batch about every 2 months. At the rate I am going my container of star san will outlive me, so if it is adding $.05 a batch I would be shocked.
 
I agree Star San is not really expensive if you save and reuse it. It does last a long time.

I think many of us who don't like the foam are not fearful of it; we just find it unaesthetic. I'm aware that the foam doesn't hurt my beer and I won't be able to taste it. I don't fear it, but I still find it unappealing. That's why I use Iodophor for all situations where foam might result if using Star San. I reserve my use of Star San for spray-on applications.
 
I use starsan and have used idophor before

I prefer starsan and use it now because of the short contact, no-rinse, no stain and i actually find the foam beneficial in sanitizing.

+ i talked to a few guys in the industry at the last beer show and they recommended starsan.
 
I use generic Betadine available at any local pharmacy.

Same disinfectant performance (1% titrated iodine) as Iodophor with better stability in solution. Plus, it's cheap. :)
 
I'd like to recast my vote to Iodaphor. I realized a very important reason why it's tits:

If you use it in a bucket, it will tell you where you need to scrub. Good old high school biology, reminding me that iodine changes sugars to a bluish color. You can quickly see where you need to wipe your bucket with a soft rag to remove the crud.

Take that, "Star San".

Star-San is both a cleaner and sanitizer. So there :D.

I really wouldnt fancy racking something I intend on drinking onto the residual foam of a sanitising [sic] solution.

Star-San actually becomes yeast food. Don't fear it!
 
I bought a 34 oz. bottle of StarSan 3 years ago when I started brewing and I still have 26 ozs. left. I have a bucket dedicated to StarSan and keep about 2 gallons stored for about three months.

When I go to sanitize things, the buckets and carboys get spritzed with a sprayer and swirled around for about thirty seconds.
All hoses stirrers etc. get dropped right in the bucket of Star San for a minute or two while I'm spritzing the other stuff.
Never an infection or aftertaste.

Leaves NO foam in the buckets or carboys and folks, it can't possibly get any cheaper. Even boiling water would be more expensive than how I do it.

You'll never convince me Iodophor is the way to go on this.
 
Star san doesn't stain my equipment, the foam can be a PIA sometimes, but I don't usually worry about it.

Cost on sanitizer is negligible, if you want clean/sanitized equipment you will pay for it, as for keeping Star-San around for months, unless you are testing the Ph, which requires an additional cost in Ph strips or meters, a 32 oz bottle will make 160 gallons of sanitizer, who cares about 15 bucks or so.

If you brewed 5 gallons a day and used 5 gallons of Star san per day it would last over a month!

+1 to spray bottles of the stuff too! I can pretty much sanitize all of my equipment with a spray bottle!:rockin:
 
Both work; when I started brewing, nearly two years ago, I began by using acidified bleach. When its shortcomings became apparent, I compared Star San and Iodophor, and there was no contest. I went with Star San, and no regrets, dozens of batches later.
 
I have been keeping a 1 quart spray bottle of starsan that I make with Distilled water. It is so convenient to keep on hand and very handy to just be able to spray anything with it. I can't really vouch as to whether one is more effective than the other though.
 
I saved a batch of Star-San made with distilled water, and each time I use it, I dribble a few more drops of concentrate into the solution to keep it acidic. Not sure if my chemistry is correct, but it seems logical to me...
 
I have both and have gone back and forth.

Now, star san 100% for when I'm bottling.

Star san for most other tasks.

Iodophor when I want to bulk clean something. Mix up a big five gallon batch, and soak all my equipment, run tons of other stuff through, etc.
 
I use iodophor once in a while, but every time I do, I wish I had gone with Star-San because it won't stain everything yellow. Once I run out of iodophor, I don't plan on buying any more.
 
I have been using idophor with good results, no infections. I have read that some people prefer starsan so I ponied up the 17 dollars just to try it. Give me some time and this new brewer will give an unbiased opinion on both. And, I have never stained a bucket or tubing using a syringe to measure my idophor. Fingers, yes....plastic no. In addition, I love the smell, it reminds me of being in the hospital where everything has to be clean. I do like the idea of starsan being able to be stored for future brews. We will see and I will post my experiences.
 
Does anyone have any input on the Five Star IO Star Iodine Sanitizer? It's an iodine sanitizer made by the StarSan people (my local brew shop doesn't carry Iodophor).
 
neither.

it's pretty silly to buy star san OR iodophor, when a tablespoon of bleach plus a tablespoon of vinegar works equally well, and it's no-rinse necessary at that density...
 
Just a side note....My wife is in the medical field, and I brought up this particular question with her. From her professional opinion, do you really need the extra iodine in your system? Even if the Idophor (or whichever iodine based sanitizer you use) is in trace amounts, and does not affect taste at all, it still puts trace amounts of iodine into the beer that we are going to be consuming. Since there is salt in almost everything, and that salt is generally speaking already iodized, do you really want to be adding even more iodine to your system?
 
neither.

Ha....Got anything else you'd like to sell me? Perhaps, a US Senate seat? :rolleyes:
 
neither.

Are you sure that's no-rinse? And if so, are you sure it's still a sanitizer at that concentration? Vinegar is only pH 2.4, so in a 5 gallon solution...

log (1 / (1 / (10^2.4) / (5 gallons * 256 tbsp/gallon))) = 5.5

I don't know that the acidity of your acidulated bleach solution is low enough to kill anything.

Plus, the sanitizing concentration for bleach is 1 part bleach in 10 parts water, so 1 tbsp bleach in 1280 tbsp (5 gallons) of water is no where near enough.

I'm not a chemist, though, so correct me if I got that wrong.
 
do you really want to be adding even more iodine to your system?

Sure...At a particularly innocuous concentration (parts per million), pick your poison:

  • iodine - readily sublimes (vaporizes)
  • phosphoric acid - readily breaks down in the presence of organic compounds
  • ammonia (quat) - readily breaks down in the presence of organic compounds
  • chlorine - oxides everything in its path! :mad:
  • ...

The only compound on the list I regularly avoid is chlorine. :)

Not all salt is iodized. I use kosher salt for almost all of my cooking, and it is definitely *not* iodized.

Thank you, Hegh. I have corrected the original post.

Fair enough. I thought I'd toss it out there. Between the information I've been collecting here, as well as bouncing it off of my wife, I've been getting quite an education.

But if the amounts are so innocuous, wouldn't the minimal amounts of chlorine also be subsequently forced to bond with the ions in the beer, thus stopping the oxidation process?
 
neither.

I would bet ya that stored star san is still cheaper, oh and I use star san to bottle because I like the idea of the yeasties eating it and only leaving beer. I'm not looking for vinegary-bleachy beer anytime in my near future.

For less than 25 cents a batch, I'll stick with my star san. Silly? Please; it's silly to try and save a quarter and end up not even sanitizing your bottles, not getting the job done, and hence just ingesting bleach for fun. THAT seems silly to me.
