Product Details
Our favorite sanitizer! Star San is an acid-based no-rinse sanitizer that is effective and easy to use.

  • Made from food-grade phosphoric acid, safe for people and the environment.
  • Star San is self-foaming, which helps it to penetrate cracks and crevices.
  • Odorless and flavorless, no need to worry about tainting your beer or wine.
  • Does not require rinsing when used at the recommended dilution.
  • Use only 1 oz Star San per 5 gallons of water and just 1 to 2 minutes of contact time.
  • Used as a soaking solution, it can also be applied by hand (wear gloves) or with a spray bottle.
  • Reusable: a solution of Star San will remain effective for up to three to four weeks in a sealed container; it is effective as long as the pH is 3 or lower.
It is safe for use on all surfaces, but use caution since it is an acid; contact with soft metals, rubber, and plastic should be kept to a minimum. Star San is environmentally friendly, biodegradable, and will not harm septic systems.

Please note, we cannot ship this product by air.

Perfect every time
7 years of cleansing and brewing with StarSan, and not a single spoiled batch due to infection. Easy to use, tasteless, not dangerous. Why would you use anything else?

fantastic no rinse cleaner
A little goes a long way on this product. I keep some of the solution in spray bottles and in gallon jugs for when I need it. Not much else to say, sanitation is the most important step in brewing.

Will never go back
I used One Step and Iodophor for years and they worked fine, but i will never go back after trying star san. The biggest benefit it has over other sanitizers is they way it coats the surface of my equipment, this saved more time than i ever expected. I will never go back to those other sanitizers.

Works great, one warning
Works great as a sanitizer, and a little bit goes a long way. One warning with this stuff- be mindful that you are using an acid, albeit a mild one. After using it for the first time while bottling, I didn't clean up all the little water spots around the counters in my kitchen, and found the next day that the finish had been etched off of the counter tops a bit. I'd suggest avoiding this if you don't want an unhappy wife.

Stings a bit
Works great, but burns my hands like crazy (even diluted). May just be sensitive to it.

star San
Great product
November 8, 2015
Buy it.
This stuff is great. I'll never use another product again. Oh, ya and ignore the foam. The foam is what makes this stuff so great really. It gives you a barrier between open air and your beer while transferring to secondary. No rush to get your bubbler back on either. Great product, buy it.
December 20, 2010
This stuff is so simple to use! I used to use the pink powdered stuff but you need to rinse it off after possibly infecting what you just sanitized. This stuff you sanitize and go on with your brew day.

Works Well
After brewing two batches, I haven't had any issues with contamination, so the Star San sanitizer seems to work well and do its job. Plus the price and volume is a good deal here. And just a little bit does the trick.
September 18, 2013
Excellent product
As a new / just starting brewer, the threat of contamination was something that really made me paranoid. Out of all the possible products available, I liked what I read about StarSan - in particular that it can be used without rinsing first, and directly in the fermentor, bottles, etc. I have used it since, starting with my first batch, and it's a wonderful product.

I know star San is a no rinse solution, but when I pour out the solution, quite a bit of foam remains in the bottle. Is this normal or did I not mix to the proper ratio?
A shopper on Feb 27, 2017
BEST ANSWER: This is totally normal. "Don't fear the foam" as they say. The foam doubles as a yeast nutrient. Get a 5 gallon bucket, mark off 1 1/4 and 2 1/2 gallon water level marks on the side with a black Sharpie marker. Fill Star San to the 1/4 oz mark for 1 1/4 gallon and to the 1/2 oz line for the 2 1/2 gallon mark. Correct ratio every time. Happy Brewing
Can i use this product in aluminium?
A shopper on Feb 23, 2017
BEST ANSWER: I have used this with aluminium for many years without any trouble. I don't leave it in long because I don't want to depassivate the metal but I honestly can't say how long that would take. Since the required contact time for non porous surfaces is less than a minute, I generally pour it in, leave it for a minute and pour it out.
In the description it says this can be stored for reuse for a couple of weeks. What kind of container is best for storing the rinse? I originally was thinking a 5 gallon plastic food grade bucket but then I saw you need to limit plastics exposure to the rinse.
S P on Feb 23, 2016
BEST ANSWER: The type of plastic that is used in your bottling bucket is resilient to Star San. So, a 5 gallon plastic food grade bucket will work great.
How many gallons does one bottle sanitize?
A shopper on Mar 5, 2017
BEST ANSWER: You mix 1/2 oz of sanitizer in 2-1/2 gallons of water so an 8oz bottle makes 40 gallons.
How safe is it on my skin?
A shopper on Feb 12, 2017
BEST ANSWER: Have had no issues at all and I have pretty dry skin in the winter. The fact is, when you're brewing you have you hands in water a lot. This by itself dry your skin. That said this stuff does not make it any worse, at it hasn't for me.
Why not rinse after using this project? Directions say not to. I don' know about you; but I don't want any thing in my wine except yeast, water, sugar, and fruit juice.
H I on Feb 28, 2016

Star San is indeed a no rinse solution. It is an acid sanitizer and at the proper dilution is safe to touch/consume in the very small amounts that would be left on your equipment.
Whats the rate for only a gallon?
S K on Jan 14, 2016
BEST ANSWER: You add about 1 ounce for 5 gallons so 1/5 of an ounce. Cheers!
It says to limit contact with plastics but I have the big mouth bubbler carbouys. Will this damage/discolor them?
J A on Dec 31, 2015
BEST ANSWER: Have used with plastic carboys. Plasic taps with no problem. I use with plastic tubing but I do rinse the tubing because it does feel a little tacky after soaking.
Can you send this product in Ukraine?
B Y on Dec 13, 2015
BEST ANSWER: Anatoliy,

I am sorry. We are only able to ship to addresses in the United States. There are a few forwarding companies out there though, that provide you with a U.S. address and we can ship to that. From there, they will be responsible for the package and any necessary documents required for shipping it to you. An online search should give you some options, if that is something you would like to pursue.
Can deluted Starsan remain in keg tubbing between kegs? 3 weeks would be the max
W A on Sep 8, 2016
BEST ANSWER: It might cause some discoloration but that shouldn't cause any issues otherwise. Ideally, I would flush it out and not leave it sit.
I made up a gal of the solution (1 tablespoon/gal) and noticed the gallon is cloudy. Does this affect the sanitizing property of the product?
Steve C on Aug 3, 2016
BEST ANSWER: Cloudiness is a sign that the sanitizer is not buffered correctly and so may not remain effective for very long, maybe just a few days or weeks. You can check pH to see if you are under 3, try adding a little extra to push the acidity high enough, consider making the solution in distilled or RO water, or just use it all soon enough. Recommended dosage is in ounces per gallon, 1 ounce per 5 gallons.
Q: will it damage granet counter tops ?
W H on Apr 18, 2016
BEST ANSWER: If your counter tops are solid granite, the acidity of Star San will not affect the counter top. Make sure that your counter tops are properly polished and sealed so like any liquid, nothing soaks into the stone. Also, ensure that your counter tops are indeed granite, there have been claims of marble being sold as granite in some areas, and Star San could possibly damage marble as there is a fair amount of calcium in its composition. I hope that this helps!
If I use Star San for sanitizing my wine-making equipment, rather than the potassium metabisulfite included with my kit, do I have to add sulfites to prevent oxidation?
Bjorn S on Mar 29, 2016
BEST ANSWER: Using Star San or metabisulfite to sanitize your equipment does not affect the oxidation of your wine. Regardless of the method of sanitization you choose, it will still be necessary to add sulfite to your wine when preparing it for bottling.
Could this sanitizer be used to clean out glass bottles used for water as well if used with the Vinator Bottle Rinser?
N G on Aug 31, 2015
BEST ANSWER: It is a very effective sanitizer and will work fine for water bottles. However, you will want to use an actual cleanser of some sort to remove any soil first. One of the powdered cleansers would work well. Simply rinse the cleanser out before using the sanitizer.
