Product Details

Our favorite sanitizer! Star San is an acid-based no-rinse sanitizer that is effective and easy to use.

  • Made from food-grade phosphoric acid, safe for people and the environment.
  • Star San is self-foaming, which helps it to penetrate cracks and crevices.
  • Odorless and flavorless, no need to worry about tainting your beer or wine.
  • Does not require rinsing when used at the recommended dilution.
  • Use only 1 oz Star San per 5 gallons of water and just 1 to 2 minutes of contact time.
  • Used as a soaking solution, it can also be applied by hand (wear gloves) or with a spray bottle.
  • Reusable: a solution of Star San will remain effective for up to three to four weeks in a sealed container; it is effective as long as the pH is 3 or lower.

Always love ordering from Widwest supplies.
This time my liquid Wyeast pack was swollen when delivered.
Can't brew for 10 days, not sure if the yeast will still be good.
Give me some feedback on it.

Great product, easy to use

This was my first time using Star San, which I purchased for sanitizing equipment for wine and cider. The product comes in a container that makes it simple to measure out the correct amount for five gallons. I have also started using this in a spray bottle for wiping down appliances and counters in the kitchen. It has no noticeable odor and is pleasant to use.
