Star San is an acid-based sanitizer that is quick, odorless, tasteless and safe for most materials except softer metals. As a high foamer, Star San's foaming action insures coverage and contact time in larger vessels and better penetration into nooks and crannys. Star San and is perfectly safe and non-toxic: any foam that is left over in your vessels or on your equipment will not harm your wine or you. Star San will not impart any flavors or odors.
Star San is easy on the environment as well: Despite being a very effective acid-based sanitizer at its prescribed concentration, raising the pH well above 3.5 (using simple baking soda or any waste PBW) renders Star San inactive as a sanitizer and the raw ingredients actually feed the aerobic bacteria found in septic systems or wastewater treatment facilities!
Use of 1 oz per 5 gallons of water and a contact time of 1 minute makes Star San very economical and convenient.
If you plan on making some up for spray applications it is best to use distilled or RO water to maximize the life of the unused portion (minerals in tap water reduce the shelf life of Star San once in solution). If a lower foaming alternative is preferred for bottling, filtering, or a final acid rinse, check out Saniclean
