Five Star Star San No-Rinse Sanitizer for Brewing, Winemaking & Beverage Equipment

Star San is a high-foaming, acid-based, no-rinse sanitizer trusted by homebrewers, winemakers, and other beverage makers for fast, reliable sanitation. It is designed to help sanitize fermenters, kegs, bottles, tubing, transfer equipment, and other brewing surfaces without adding a rinse step to your process.

Its self-foaming action helps the solution reach cracks, crevices, and other hard-to-clean areas, while the no-rinse formula keeps brew day moving. When used as directed, Star San is odorless, flavorless, biodegradable, and safe for use on plastic, glass, and stainless steel.

Why Brewers Choose Star San

• No-rinse convenience: Sanitize equipment and move straight into brewing, bottling, or kegging.
• High-foaming coverage: Foam helps reach into seams, valves, tubing, and other small spaces.
• Fast working solution: Use at 1 oz per 5 gallons of water with a 1 minute contact time.
• Broad brewing compatibility: Suitable for plastic, glass, and stainless steel equipment when used as directed.
• Easy measuring on larger bottles: 16 oz and 32 oz sizes include an integrated measuring and dispensing chamber.

How to Use Star San

• Mix: Dilute 1 oz of Star San per 5 gallons of water.
• Apply: Spray, soak, or circulate so all surfaces stay fully wet.
• Wait: Allow at least 1 minute of contact time.
• Drain: Let excess solution drain. No rinse is needed when used correctly.

Helpful Use Notes

• Available sizes: 8 oz, 16 oz, and 32 oz.
• Water quality matters: Distilled or RO water can help mixed solution stay clearer longer than hard tap water.
• Cloudiness note: If a mixed solution turns cloudy, hard water minerals may be the cause.
• Material caution: Because Star San is acidic, minimize contact with soft metals.

If you want a proven brewery sanitizer that is easy to mix, easy to use, and trusted across home and professional beverage making, Five Star Star San remains one of the best go-to options for keeping equipment ready for the next batch.
