Brewday Essential #1
The Industry Standard No-Rinse Brewing Sanitizer
4.998/100
Five Star Star San High-Foaming Acid Sanitizer (32 oz)
$27.99Ask 100 experienced craft brewers what equipment is most vital to making good beer, and 99 will say sanitation. Five Star Star San is a high-foaming, acid-anionic no-rinse sanitizer. Its self-measuring dose bottle dispenses 1 oz per 5 gallons of water. The persistent foam penetrates microscopic crevices in plastic fermenters, ball valves, and vinyl tubing that liquid rinses miss. As long as the solution stays below pH 3.5, it remains active indefinitely.
✓ No-rinse formulation eliminates contamination risks from municipal tap water after sanitizing
⚠ Do not use on soft metals (copper, aluminum) for prolonged contact due to low pH acidity
