Star San is the sanitizer par excellence for pro brewers and hobbyists alike. It’s safe, it’s convenient, and it’s effective. It’s so ubiquitous, though, that even longtime brewers may not pay it a second thought. But paying a second thought isn’t a bad idea when the quality of your beer is at stake. Here are a few Star San dos and don’ts to help you get the most out of everyone’s favorite wonder foam.
DO follow the recommended dilution instructions. Just 1 ounce (30 ml) of Star San in 5 gallons (19 liters) of water is enough to effectively sanitize all of your gear.
DO use the Star San bottle’s handy dosing feature to measure out the amount you need. Ensure that the cap over the main reservoir is closed, and slightly loosen the cap over the smaller dosing cavity. Then just squeeze the bottle until Star San fills the dosing cavity to the level you want. Remove the cap, and pour out your measured dose.
