How to Aerate Wort

Introducing oxygen into your wort before fermenting is an easy, effective way to improve the quality of your home brew.


  • Step 1: Sanitize equipment Sanitize everything that will come in contact with the wort using sodium percarbonate and then rinse thoroughly.
  • TIP: Use a bleach solution. Add two capfuls of bleach per five gallons of water.
  • Step 2: Cool the wort Cool the wort to between 60 and 75 degrees Fahrenheit before introducing air into it. Transfer the cooled wort to the fermenting bucket.
  • TIP: Leave room inside the bucket, as the wort expands during aeration.
  • Step 3: Aerate Attach the paint mixer to the power drill. Stand directly over the bucket, submerge the mixer, and turn the drill on.
  • Step 4: Mix Mix until the desired level of air is incorporated into the wort; a few minutes are usually sufficient. Be careful of spills.
  • Step 5: Let settle Give the foam enough time to settle before topping off with the desired amount of water.
  • FACT: There were 1,525 breweries operating in the U.S. in 2009.
