Brew Tip - Preheat Wort Chiller

When sticking your immersion wort chiller into your brew pot does it kill your boil? Try preheating your wort chiller by setting it above your brew pot for about five minutes. The steam coming off the boil will warm up the coils. I will also crank the heat all the way up right before I put in the chiller. No more dead boils. Happy brewing!


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.

Old Small Wort Chiller

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.

Immersion Wort Chiller Hose Clamps

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.
