From the product description, check product page for current description, price and availability:

  • Self-foaming acid sanitizer ideal for brewing, dairy and other food and beverage equipment
  • Extremely effective bactericide and fungicide and is not affected by excessive organic soils
  • Reduces water spotting and can be used without rinsing under the proper concentrations
  • Volume: 8 fluid ounces

Star San is my sanitizer of choice.  It is effective, food safe and no-rinse.  It is also very cost effective if you use the spray bottle method.

My Favorite Size and Why: Considering the shelf life of Star San concentrate is 1 to 2 years, If you’re using the Spray Bottle Method [See: Tip: Star San Tips, Tricks and Guidelines – Using Star San In a Spray Bottle], I generally recommend purchasing the 8 ounce size.  8 ounces of concentrate yields about 39 gallons of mixed solution.  The spray bottle method is very efficient, so you don’t end up using much sanitizer per batch.  Let’s say you use 1/4 gallon (which I personally think is high) for each batch, the 8 ounces size yields enough mixed solution for around 157 batches.  That figures to about 13 batches per month over a 1 year period.  If you use 1/8 gallon (which I think is more realistic) that equates to about 26 batches per month over a 1 year period.  The larger 16 and 32 ounces sizes may be a lower cost per ounce, but if you’re unable to use it within Star San’s shelf life, you’ll just be throwing sanitizer away or using less effective past date sanitizer.  Getting a smaller bottle more often means your Star San is fresher.
