Star San: An Effective and Safe Sanitizing Solution for Beer and Wine Makers
Posted by Matteo Lahm on 27th Jul 2023
As a beer or winemaker, you are always fretting about the importance of sanitation, quality and safety. Star San is an ideal sanitizing solution for your beer and wine because it is composed of a safe blend of chemicals that effectively eliminates bacteria, unwanted yeast and other microorganisms without leaving any residue.
Star San is a blend of phosphoric acid and dodecylbenzenesulfonic acid. The effectiveness of this synergistic combination leaves equipment in an acid state that eliminates water spotting, mineral build-up, and corrosion. It is a no-rinse sanitizer that utilizes a foam to sanitize equipment and surfaces. As a self-foaming acid anionic detergent, it clings to surfaces and hard-to-reach places, providing you with a more effective sanitizing action than liquid sanitizers that do not foam. Believe it or not, the foam is actually good for your yeast because it contains DDBSA and Phosphoric Acid. When pH increases, these compounds break down and act as a nutrient.
If you want to limit the foam, it is best to pour it gingerly or siphon it in and out of your vessels. This is especially important with carboys and demijohns. The bubbling that happens when they are emptied agitates it, which increase the amount of foam. You do not need excessive amounts to get the job done. If it does foam up too much, you can just let your containers rest for a bit and it will diminish on its own in just a few minutes.
Preparing Star San is easy. Mix two ounces with four gallons of water and allow contact with your tools and vessels for two minutes. Do not rinse after use because that will cause recontamination.
For all its benefits, there are some safety precautions to be taken when using Star San. Wear gloves as it can irritate your skin and avoid getting it in your eyes. It is also not recommended for use on soft metals because of the acid nature of this product. That said, the only metal you should be using anyway for beer and winemaking is stainless steel or copper, which is perfectly suited for Star San. Lastly do not mix Star San with any chlorinated cleaners or it will produce chlorine gas. Stick to the recommended formula of just Star San and Water.
In addition to its sanitizing properties, Star San has low toxicity and minimal odor. For beer and winemakers, Star San offers you an effective and safe sanitizing method that will not interfere with the flavor of your wine and beer.
