Do It Yourself Immersion Wort Chiller

Chill out man!

Immersion Wort Chiller

I had a ¼”” outside diameter 15’ wort chiller that I would use for my partial boils. This wort chiller combined with a sink ice bath would usually get me to yeast pitching temp in a feasible time. Now that I have switched to all grain I am boiling at least 5 gallons of water. This can take a significant amount of time to chill down to yeast pitching temperature. I also use a keggle, so immersing that in a tub of ice water isn’t really practical.

I decided it was time to build a proper immersion wort chiller. I bought 50’ of ½” copper tubing. I was going to solder on connections but I decided to just fit hose over the ends with hose clamps, it was much cheaper.

I tried to use hose benders, those spring looking things, but they didn’t seem to work on the sharp bends. Oh well, I could always cut those off and reform the copper.

I made sure the output hose on my work chiller was long enough to reach the washing machine. I drain the hot water from the wort chiller into the washing machine and then run a load of laundry.

The input on the wort chiller hooks up to a garden hose so it didn’t really matter how long this was.

Input for Immersion Wort Chiller

I didn’t have a corney keg to wrap the copper around so I use a large pot strainer. It was a good diameter but it is a little too skinny for my 15 gallon keggle. The top 4 coils are out of the wort.
