Star San is a flavorless, odorless, no-rinse food grade sanitizer. When used according to directions, Star San will completely eliminate all microorganisms that it comes into contact with by lowering the pH to a level that will destroy them quickly (5 minutes), and foams to sanitize cracks, crevices and other 'impossible' places in your equipment. Once fresh wort/must is added to your fermenter the pH will quickly rise to a level that is not only safe for yeast, but sometimes beneficial, making Star-san a true no-rinse sanitizer.
