Simple DIY Wort Chiller, (Under $30)

The Parts and The Tools.

Part 2 of my DIY Brewing Equipment Project: The Cheapie Wort Chiller.

     I'll admit to growing weary of working the sink bath of ice and cold water every time I cool down my wort... It is not the most convenient method, even if it only costs the price of a Big Bag of Ice and the water necessary to fill a sink basin. So I decided to make a Wort Chiller, like many other homebrewers looking to save some money.

     This project cost less than $30, which was a great price compared to what is available for purchase elsewhere. If you have read my DIY Mash/Lauter Tun post, you are already aware of the experience I have with helping other homebrewers put this type of apparatus together (I sell plumbing supplies for a living). This is the result of much pondering over the most efficient method of making my own immersion-style chiller... which can easily be converted into a pass-through chiller as well, but I'll play with that idea later when I have converted the spigot on my lauter tun. Like the mash/lauter tun all these supplies came from one major retail chain.

     This parts list is also relatively short and simple:

          (1) 3/8 Soft refrigeration Copper Coil, 10'          $13.48
          (1) 1/2" O.D., 3/8" I.D. vinyl tubing, 10'             $4.38
               (the roll pictured is 20', but only 10' is needed for this project.)
          (1) Brass 3/4" FHT x 3/8" Barb adapter             $7.65
          (3) 5/8" Stainless Steel Hose Clamps                 $2.55 ($0.85ea)
                                                                                   $28.06 Total

      If you don't have access to a tube bender, you can use any solid cylindrical object to aid you in bending the copper. Reminder: Please use Caution to avoid kinking the tubing, because copper is rather soft and recklessness can ruin your material. I made some of my bends around the base of this jar of beans, just to illustrate this point.

Copper Sculpture can be Pretty!

     The trickiest bends will be the inlet and outlet positions. Just use a smaller cylinder if necessary to make these tight bends. It is OK to bend past the angle you need and then back it up a bit.
    
     The next part is easy... just cut how much length you need to discharge where you will be brewing or just use half your vinyl tubing. Secure it to the discharge end of your coiled sculpture with a stainless steel hose clamp. tighten it down just enough to be very snug... but do not over-tighten, remember how soft that copper is.

     Do the same for your inlet end; this is the tube that will connect to your faucet after you add the last part. that hose adapter barb will fit right into the other end of this tubing and a hose clamp will keep it secure. If you do not have a hose thread connection to hook up to (like on a standard kitchen faucet) you can easily pick up an adapter at any hardware store. I already had one for use with my bottle washer.

     And that is it! You can use a 20' coil if you would like to increase the amount of area that will be available to contact the wort for expediency, just double the price expectation of the copper.

     I still intend to immerse my brewpot into a bath of ice water... however I expect the Wort Chiller to significantly reduce the time it takes to cool my wort down, and the amount of refilling and draining necessary to provide constant cold temperature to an ice bath alone. That is, to me, worth the cost of making the device and it is a lot of fun to make your own equipment. I like the idea of not only brewing my own Beer, but hand-crafting the implements to do so! I intend to improve and update these builds in the future and I will link to the new posts from these older ones.

The Final Contraption.

     If you have read this and found it useful, I am glad to have been some help. If you are only reading this because you actually like me or were too bored to do anything else, well, "Thank's for noticin' me." (You know who Eeyore is, don't front like you don't get it!)
