Five Star Star San is a fast-acting, self-foaming, no-rinse acid-based sanitizer. It's easy to use and non-toxic. It's a mix of phosphoric acid and dodecyl benzene sulphonic acid and will not affect the smell or taste of your fermented beverage. After sanitizing you may notice suds left over from the Star San, but fear not, those bubbles mean the sanitizer has been hard at work and will not effect your beer.
*Usage: 1 ounce per 5 gallons = 300 ppm and is the recommended dosage. Allow 1-2 minutes contact time.
