Homemade Wort Chiller (With “How To” Video)

When I started brewing beer, I was working with limited equipment for two main reasons: I didn’t want to spend a ton of money up front and I didn’t really know what all of the “extra” equipment was. Some of this “extra” equipment can sound complicated to the beginning brewer, and if it’s not absolutely necessary then who needs it, right?

Well once I got the hang of my very primitive brewing process, I began to get more curious about how I could improve my brew days. I realized that one of the most tedious parts of my brew day was chilling my wort from boiling temperature to fermenting temperature. After a little bit of research, I decided that I could improve my beer (and my brew days) by getting an immersion wort chiller. Let me tell you, I will never go back to brewing without one!

Rather than waiting nearly an hour to cool my wort, I can now chill my wort in less than 20 minutes! If you haven’t started using a wort chiller yet, then I highly recommend that you check out my video below where I tell you the benefits of a wort chiller and how you can make your own at a relatively low cost.

Please note that copper will oxidize if left sitting for extended periods of time. This oxidation will appear green/blue in color and is toxic if not properly cleaned off before brewing. Cleaning is simple, and I do this by soaking my chiller in a vinegar solution for about 15 minutes to an hour, depending on the amount of oxidation.

What you need:

  • 3/8″ OD copper tubing (I suggest at least a 20′ coil)
  • About 5′ 3/8″ OD of tubing (I used vinyl, but silicone is another popular option, this will not come into contact with your beer)
  • 3 tube clamps (and a screw driver to tighten them)
  • A hose or faucet adapter
  • A spring-type tube bending tool (optional)
  • Scissors
  • Brew kettle (for reference)


If I left any questions unanswered, I would love to hear from you! If you don’t think you’re up for making a wort chiller yourself, then send me a message and I can make one for you.

Thanks for stopping by today, and I look forward to hearing all about how your new homemade wort chiller turns out; cheers!
