Star San® Acidic Sanitizer

If you’ve ever brewed beer, crafted cocktails, or served beverages through a draft system, you know how critical sanitation is. One missed spot can turn your carefully crafted drinks into a breeding ground for bacteria and off-flavors. That’s where Star San by Five Star Chemicals steps in—trusted by professionals and homebrewers alike. Star San is a no-rinse, acid-based sanitizer designed to keep brewing and beverage equipment clean and microbe-free. Its fast-acting formula kills bacteria, mold, and yeast in just one to two minutes of contact time. Because it’s a no-rinse sanitizer, it’s convenient for quick turnarounds, leaving behind a flavorless, food-safe residue that won’t affect your beverages. Brewers often say, “Don’t fear the foam,” since the foaming action helps reach hard-to-clean spots.
